Frequently Asked Questions

Built-in Screen Time shows you how much you're using your phone, but it can't actually block you from using apps. Hazel goes further with real-time blocking, friction layers (delays before access), and intelligent habit tracking. While Screen Time provides basic insights, Hazel adds actionable tools to help you change your behavior.

Hazel uses iOS Shortcuts and ScreenTime APIs to create friction, not complete unbreakable locks. This is by design—research shows that forcing complete blocks often backfires. Adding friction (like a 30-second delay) is more effective for long-term habit change. You can always override, but the delay makes you pause and reconsider.

Currently, Hazel is available exclusively on iOS. An Android version is planned for Q2 2026. For now, Android users can explore alternatives like AppBlock or StayFree, though Hazel's unique approach with friction layers and habit insights is iOS-specific.

Freedom's biggest strength is cross-device blocking—it works on Mac, Windows, iOS, and Android. If you need to block distracting websites and apps across all your devices, Freedom is great. One Sec focuses on friction layers (delays) but doesn't offer real-time blocking or detailed analytics. I'm iOS-only but offer integrated habit tracking, detailed analytics (both easy tidbits and nerdy analytics), and different types of blocks—from soft to hard—that help you actually change your behavior.

No. Hazel uses iOS's built-in Screen Time APIs and Shortcuts, which are designed to be battery-efficient. The app runs in the background using system-level APIs rather than constantly monitoring, so battery impact is minimal. Most users report no noticeable battery drain.

Yes. All screen time data stays on your device. Hazel uses iOS Screen Time APIs that Apple designed to keep data local and private. We don't collect, store, or transmit your usage data to any servers. Your privacy is protected by Apple's system-level security.

Yes. Hazel allows you to set personalized daily limits by individual app or by category. You can create custom schedules that work for your week, setting stricter limits during work hours and more flexibility during designated free time. This granular control helps you build healthier habits without feeling overly restricted.

Time tracking shows you minutes wasted. Habit tracking shows you behavior change. Hazel tracks how many times you successfully resisted opening a blocked app, which times of day you struggle most, and how your discipline improves week-over-week. These metrics predict real habit change better than total screen time. Traditional apps tell you the problem. Hazel shows you the progress.

Research shows that hard blocking creates willpower battles that people eventually lose, leading to binges when they break through. Friction layers—like a 5-second or 30-second delay—interrupt the automatic habit loop without creating a punishment scenario. This psychological approach is more effective for long-term habit formation because it breaks the cycle at the moment of impulse, not through force.

No. Hazel uses private streaks, badges, and milestones that are visible only to you. Research shows that private motivation through personal progress tracking is more sustainable than competitive leaderboards. We focus on individual growth, not social pressure. Your progress, your way—no competition, just growth.
