Features
8.5

This is where Readwise Reader really shines. The features are genuinely impressive - not just marketing fluff, but stuff that actually makes reading online better.

What we love:

  • Everything Actually Works Together: Throw in web articles, newsletters, PDFs, ebooks, even Twitter threads - it all just works in one app
  • Highlighting That Doesn't Disappear: Highlight on your phone, it's there on your laptop. Highlight images, text, whatever. It remembers everything
  • AI That's Actually Helpful: Ask questions about what you're reading, get definitions, simplify confusing passages. It's like having a smart friend reading with you
  • Text-to-Speech That Doesn't Sound Like a Robot: Seriously, this is good enough that you'll actually use it during commutes
  • Notes Go Where They Should: Your highlights automatically show up in Obsidian, Notion, wherever you keep notes. No more copy-pasting
  • Sync That Just Works: Start reading on your phone, continue on your laptop. It knows where you left off

The rough spots? Search is surprisingly bad for such a polished app. Some stuff doesn't work great on e-readers. We hit bugs that shouldn't exist in a paid app. But the core features solve real problems and do it well.

7.5

Thunder VPN delivers a solid foundation of core VPN features that meet the basic needs of most users. The app's feature set is straightforward and focused on simplicity rather than advanced functionality, which aligns well with its target audience of casual VPN users.

Key features we found most valuable include:

  • Unlimited Bandwidth: Unlike many free VPNs that impose data caps, Thunder VPN offers truly unlimited data usage, making it suitable for streaming and heavy browsing
  • One-Tap Connection: The interface is designed for simplicity with a prominent connect button that automatically selects the best server
  • Global Server Network: Access to servers worldwide for bypassing geo-restrictions and accessing blocked content
  • No Registration Required: Users can start using the VPN immediately without creating accounts or providing personal information
  • Manual Server Selection: Choose specific server locations for optimal performance
  • Minimal Advertising: Much less intrusive ads compared to other free VPNs

However, Thunder VPN lacks many advanced features that users expect from premium VPN services. There's no kill switch to protect against connection drops, no split tunneling to route specific apps through the VPN, and no specialized servers for streaming or torrenting. The server selection is limited compared to premium alternatives.

While the core features work well for basic privacy and geo-unblocking needs, power users will find the feature set limiting. For users who need advanced features like kill switches, split tunneling, or specialized servers, alternatives like Proton VPN offer more comprehensive free tiers, while NordVPN provides extensive advanced features for premium users.

We rate features at 7.5 out of 10—good for basic VPN needs with better user experience than most free alternatives, but lacking the depth that serious users require.

Performance
7.0

Performance presents a tale of two experiences - the core reading functionality works smoothly and reliably, but recent updates have introduced stability issues that affect the overall user experience.

The strong points are evident during daily use. Reading feels responsive with smooth scrolling and quick page navigation. Content synchronization across devices works consistently, and importing articles, PDFs, and RSS feeds processes efficiently. The basic reading, highlighting, and annotation functions that form the app's foundation operate reliably.

Recent developments tell a different story though. The significant drop from a 4.3 overall rating to 3.78 for recent reviews signals genuine stability problems with newer versions. Android users report more issues than their iOS counterparts, including navigation problems and functionality regressions. Some users have experienced critical issues like being unable to add new content after updates, while others consistently note that search performance remains poor.

Device compatibility also varies, with particular issues reported on e-ink devices and certain Android configurations. While active development appears to be addressing these concerns, the reliability issues prevent the app from achieving the stability users expect from a paid service.

6.5

Thunder VPN's performance presents a mixed picture that reflects the challenges of maintaining a free VPN service. While the app can deliver fast connections when working properly, reliability issues significantly impact the overall performance experience.

Performance strengths include:

  • Fast Connection Speeds: When connected, users report good speeds for browsing and streaming
  • Quick Connection Times: The app connects to servers relatively quickly when the connection is stable
  • Global Server Network: Access to servers worldwide provides good coverage for geo-unblocking
  • Lightweight App: The app itself is relatively small and doesn't consume excessive system resources
  • Minimal Advertising: Much less intrusive than competitors, improving perceived performance

However, significant performance issues undermine the user experience:

  • Frequent Connection Drops: Users consistently report that connections drop frequently, requiring reconnection
  • Inconsistent Reliability: Connection quality varies significantly between sessions and servers
  • Must Keep App Open: Users must keep the app window open to maintain connections, which can be inconvenient
  • Connection Instability: Many users report that the VPN disconnects after a few minutes of use
  • Slow Loading Times: Some users report occasional slow loading times

User reviews reveal a pattern of performance issues, with many users praising the app's speed when it works but complaining about frequent disconnections. The app's focus on user experience over aggressive monetization may be impacting server quality and maintenance.

For users seeking reliable performance, alternatives like Proton VPN offer more consistent free performance with better server maintenance, while NordVPN provides premium performance with dedicated servers and better reliability guarantees.

We rate performance at 6.5 out of 10—good speeds when working but undermined by frequent connection drops and stability issues that create an inconsistent user experience.

Design
7.5

The design philosophy centers on creating a distraction-free reading environment, and it largely succeeds. Users consistently describe the app as "gorgeous," and the overall aesthetic genuinely supports focused reading with clean typography and thoughtful spacing.

Design strengths that impressed us:

  • Clean Reading Interface: Minimal distractions with focus on content consumption
  • Consistent Visual Language: Cohesive design across different content types (articles, PDFs, ebooks)
  • Customizable Reading Experience: Good control over fonts, spacing, and display preferences
  • Intuitive Navigation: Logical information architecture for managing large content libraries

The cross-platform execution reveals some inconsistencies though. The app clearly prioritizes iOS, and this shows in the Android experience. Navigation elements don't always follow Android design conventions, and gesture interactions occasionally feel foreign to the platform. While the core reading experience remains visually appealing, the iOS-first approach creates noticeable polish differences that affect the overall experience on Android devices.

8.0

Thunder VPN's design philosophy centers on simplicity and user experience, which works exceptionally well for its target audience. The interface is clean, intuitive, and focuses on functionality rather than flashy design elements.

Design strengths we observed include:

  • Clean Interface: The main screen features a simple, intuitive layout with the connect button as the focal point
  • Clear Visual Feedback: Connection status is clearly indicated with color-coded states (connected/disconnected)
  • Minimalist Approach: The app avoids overwhelming users with complex settings or technical jargon
  • Consistent Branding: The visual design maintains consistency across different screens
  • Accessible Design: Large buttons and clear text make it usable for users of all technical levels
  • Minimal Advertising: The app's focus on user experience means less intrusive advertising

The design experience is significantly better than competitors like Turbo VPN and Now VPN, with much less advertising interruption. Users consistently praise the app's clean interface and ease of use, making it one of the most user-friendly free VPNs available.

While the core interface design is solid, some users report that the app requires keeping the window open to maintain connections, which can be inconvenient. However, this is a minor issue compared to the overall design quality.

For users who value a clean, uninterrupted interface, Thunder VPN offers one of the best free experiences available. Alternatives like Proton VPN offer similar design quality with better privacy protection, while Windscribe VPN provides a comparable free experience with fewer restrictions.

We rate design at 8.0 out of 10—excellent design principles with minimal advertising that creates a genuinely user-friendly experience.

Value for Money
7.5

The value proposition is complex and heavily depends on your reading habits and tolerance for subscription models. The subscription approach generates polarized reactions - some users find it completely worthwhile while others strongly prefer one-time purchases.

For power users, the comprehensive feature set justifies the cost. AI assistance, advanced highlighting, deep integrations, and reliable infrastructure create genuine productivity benefits. The 30-day trial period (with no credit card required) provides ample time to evaluate whether the app fits your workflow, and active development means you're paying for ongoing improvements.

The subscription model does create barriers though. Unlike competitors, there's no permanently free tier with basic features, and the recurring cost adds up over time. Some users feel the subscription requirement should be more prominently displayed upfront, and occasional bugs or missing features (like robust search) can impact the perceived value when you're paying monthly.

For serious readers who can utilize the full feature set and don't mind subscription costs, the value proposition is solid. Casual users or those preferring one-time purchases will likely find better alternatives elsewhere.

8.0

Thunder VPN's value proposition is significantly better than most free VPNs, offering a genuinely useful free service with minimal advertising and good performance. The app provides excellent value for users who can tolerate occasional connection issues.

Value strengths include:

  • Truly Free Core Service: Unlimited bandwidth and server access without time limits or data caps
  • No Upfront Costs: Users can start using the VPN immediately without payment or registration
  • Unlimited Usage: Unlike many free VPNs, there are no daily or monthly data limits
  • Global Server Access: Free access to servers worldwide for geo-unblocking
  • No Registration Required: Start using the service immediately without providing personal information
  • Minimal Advertising: Much less intrusive than competitors like Turbo VPN and Now VPN

The free tier's value is significantly better than most free VPNs, with minimal advertising and good performance. However, some limitations affect the overall value:

  • Connection Stability: Frequent connection drops require reconnection
  • Must Keep App Open: Users must keep the app window open to maintain connections
  • Limited Advanced Features: No kill switch, split tunneling, or specialized servers

The premium pricing is reasonable ($1.99-$59.99), but the connection stability issues may not justify the upgrade for many users. Premium VPN services like NordVPN and Surfshark VPN offer more comprehensive features and better reliability for similar or lower costs.

For users seeking genuine value, Thunder VPN offers one of the best free experiences available. Alternatives like Proton VPN offer a more generous free tier with better privacy protection, while Windscribe VPN provides a more reliable free experience with fewer restrictions.

We rate value for money at 8.0 out of 10—excellent value for a free VPN with minimal advertising and good performance, though connection stability issues limit the overall experience.

Ease of Use
7.0

The usability picture is mixed - while the core reading experience feels intuitive once you're up and running, several barriers can frustrate new users during the initial setup and exploration phases.

Where the app excels in usability:

  • Intuitive Reading Controls: Highlighting, bookmarking, and annotation tools are discoverable and easy to use
  • Smooth Content Import: Adding articles, PDFs, and connecting RSS feeds works reliably
  • Logical Organization: Content management and library organization follow expected patterns
  • Responsive Interface: Most interactions feel immediate and predictable

The friction points become apparent early on though. The mandatory account creation before even testing the app frustrates many potential users, and Android users face additional hurdles with gesture navigation that doesn't behave as expected. The wealth of features also means there's a genuine learning curve - power users eventually find everything intuitive, but newcomers need time to discover and understand all capabilities. These initial barriers prevent the app from being truly accessible to everyone, despite its strong foundation once you're familiar with it.

7.0

Thunder VPN excels in basic usability with its one-tap connection approach, making it one of the most accessible VPN apps for beginners. The core functionality is genuinely simple and requires no technical knowledge to operate effectively.

Usability strengths include:

  • One-Tap Connection: The primary action is as simple as tapping a single button—no configuration or technical setup required
  • No Registration: Users can start using the VPN immediately without creating accounts or providing personal information
  • Automatic Server Selection: The app handles server selection automatically, removing the complexity of choosing optimal servers
  • Clear Status Indicators: Connection status is immediately visible with clear visual feedback
  • Cross-Platform Consistency: The interface works similarly across Android and iOS devices
  • Minimal Advertising: Much less intrusive than competitors like Turbo VPN and Now VPN

However, the ease of use is somewhat undermined by connection stability issues. Users report that the app requires keeping the window open to maintain connections, which can be inconvenient. Additionally, frequent connection drops require reconnection, which interrupts the user experience.

While the core interface is genuinely easy to use, the connection stability issues compromise the overall user experience. For users seeking a truly hassle-free VPN experience, alternatives like Proton VPN offer a cleaner free tier with better connection stability, while Windscribe VPN provides a more reliable free experience.

We rate ease of use at 7.0 out of 10—excellent core usability with good interface design, but undermined by connection stability issues that require user intervention.

Security & Privacy
8.0

Readwise Reader handles security and privacy reasonably well for a cloud-based reading service, though the nature of the product requires some data collection and account management that privacy-conscious users should be aware of.

Privacy and security strengths:

  • Transparent Data Usage: Clear about what data is collected and how it's used for the reading experience
  • Secure Sync Infrastructure: Reliable cross-device synchronization without apparent data loss or corruption
  • Professional Service: Established company with clear business model (subscription-based, not ad-supported)
  • Data Portability: Users can export their highlights and annotations

Areas of privacy consideration:

  • Required Account: Mandatory sign-up means your reading habits and content are associated with your identity
  • Cloud Storage: All content and annotations are stored on Readwise servers rather than locally
  • Content Analysis: AI features like GhostReader require processing your reading content
  • Email Marketing: Some users mentioned receiving marketing emails, though unsubscribe options are available

For a service that fundamentally requires cloud sync and AI processing, Readwise Reader handles privacy appropriately. However, users seeking maximum privacy might prefer local-only solutions. We rate security and privacy at 8.0 out of 10.

6.0

Thunder VPN's security and privacy practices present a mixed picture that raises some concerns for privacy-conscious users. While the app claims to offer secure connections and privacy protection, several factors undermine confidence in its privacy commitments.

Security strengths include:

  • Encrypted Connections: The app provides encrypted tunnels for data transmission, protecting users on public WiFi networks
  • No Registration Required: Users can use the service without providing personal information or creating accounts
  • Basic Privacy Protection: IP address masking and location spoofing for basic privacy needs
  • Standard VPN Protocols: Uses established VPN protocols for secure connections
  • No-Logging Policy: Claims to maintain a strict no-logging policy

However, some privacy concerns emerge from user feedback and business practices:

  • US-Based Developer: The developer is located in the United States, which raises questions about data jurisdiction and potential government access
  • No Independent Audits: Unlike premium VPNs, Thunder VPN hasn't undergone third-party security audits to verify its privacy claims
  • Data Harvesting Concerns: Some users report concerns about data harvesting, though this isn't explicitly confirmed
  • No Transparency Reports: No public transparency reports about government requests or data handling practices
  • Free Service Concerns: The completely free model raises questions about how the service is monetized

User reviews reveal mixed experiences, with some users praising the app's privacy features while others express concerns about data collection. The lack of transparency about the service's data handling practices further undermines trust.

For users who prioritize privacy and security, alternatives like Proton VPN offer Swiss-based privacy protection with independent audits and transparency reports, while Windscribe VPN provides Canadian privacy protection with more transparent data handling practices.

We rate security and privacy at 6.0 out of 10—basic security features present but concerns about data handling, jurisdiction, and transparency that compromise trust in the service.

Conclusion

After weeks of actually using Readwise Reader, we're impressed. It's not perfect, but it genuinely solves the "reading stuff scattered everywhere" problem that drives us crazy. The highlighting works great, the AI assistant is actually useful (shocking!), and having everything sync to your notes automatically is pretty amazing.

The downsides are real though. The subscription model will annoy people, you can't try it without making an account first, and if you're on Android, it's going to feel a bit clunky. Plus, for a paid app, it crashes more than we'd like.

But here's the thing - if you read a lot online and you're tired of managing content across multiple apps, this might change how you work. The 30-day trial is long enough to really test it out. Just don't expect perfection, expect a really good tool that keeps getting better.

Thunder VPN represents one of the better free VPN options available, offering a genuinely useful service with minimal advertising and good performance. While the app delivers on its core promise of free, unlimited VPN access with simple one-tap connection, connection stability issues and the need to keep the app window open create some usability concerns.

The app's exceptional popularity (100M+ downloads, 4.8-star rating) reflects genuine demand for a user-friendly free VPN service, and many users do find value in its basic functionality. However, the frequent connection drops and stability issues suggest that the free model may be impacting server quality and maintenance. For users who can tolerate occasional connection issues, Thunder VPN provides a functional free VPN with minimal advertising.

For users seeking a more reliable free VPN experience, Proton VPN offers better privacy protection and connection stability, while Windscribe VPN provides a more reliable free tier with fewer restrictions. For those willing to pay for premium features, NordVPN and Surfshark VPN offer more comprehensive solutions with better reliability and privacy guarantees.
