Just vibes. ◆ WHAT MAKES HAZEL DIFFERENT Unlike other screen time apps that feel like punishment, Hazel makes it fun to stay focused: ◆ DAILY STREAKS - Build momentum, not guilt Watch your streak grow as you stick to your goals.

Every small win counts. ◆ FUN ANALYTICS - Actually understand your screen time Boring graphs? Not here. Our insights are designed to be engaging and easy to understand. Cool colors, simple numbers, real insights. You'll actually *want* to check them. ◆ THREE FLEXIBLE BLOCKS - Control your way • Schedules - Block apps during specific times (class, work, sleep) • Time Limits - Set daily caps on your worst apps • App Locks - Limit how many times you can open an app per day Pick what works for you. No judgement, no shame. You're in control. ◆ LIGHT, EASY UI - Built for your vibe No scary screens, no corporate energy. Hazel is designed to feel friendly and approachable. Our warm colors and cute design make taking control of your screen time actually pleasant. ◆ NO GUILT, NO SHAME We know you're not "addicted." You just want more focus.

Hazel is. ◆ MAKE IT FUN With daily streaks and rewards, staying focused becomes a game you actually want to play. Compete with friends (or yourself). Celebrate wins. Treat your phone like something you control, not something that controls you. ◆ YOUR DATA, YOUR CONTROL Your data stays on your phone. Always. We use Apple's own Screen Time technology—the same thing that powers Apple's built-in controls. You're in good hands. Your privacy? Sacred. ◆ DESIGNED WITH CARE Hazel is built with a warm, earthy color palette and a cute hedgehog mascot because staying focused should feel good, not scary. Every animation is smooth. Every button is thoughtful. This isn't corporate—this is made with love. ◆ START YOUR STREAK TODAY Download Hazel and join thousands of people who are taking control of their screen time—guilt-free.
