Earn Screen Time

Move first. Scroll later. Earnit helps you interrupt automatic scrolling by earning your screen time. Choose distracting apps, earn minutes through effort, then decide when to use them. YOUR MINUTES, YOUR CHOICE 1. Choose the apps you want to block. 2. Earn minutes with walking steps from Apple Health. 3. Start a 5, 10 or 15 minute access session when you're ready. Earning minutes builds your balance. You choose when to unlock. A session is a window of clock time, even if you switch apps or lock your phone. Restrictions are reapplied when the session ends, subject to iOS timing. MORE WAYS TO EARN WITH PRO Do push-ups, squats, jumping jacks or lunges counted by your iPhone camera, or scan study material and answer a comprehension question. Study needs an internet connection; it rewards understanding rather than time on a study timer. Push-up video is not recorded or uploaded. START WITH ONE EARNED UNLOCK A DAY Try the daily earned unlock without a subscription. Pro adds more access sessions, custom earning rates, study and advanced progress views. Build a balance before opening your usual distractions. Start with a walk, then choose your next session. KEEP GOING WITH FRIENDS Add friends by invite code, create or join a squad and compare weekly goal progress. Send nudges and cheers to support each other. Choose whether to share missed goals. Friends shares steps, earned minutes and streaks; your selected apps and app usage stay private. โ€”โ€”โ€” Unlock Earnit Pro with a monthly subscription or a one-time Lifetime purchase. The monthly plan includes a 3-day free trial for eligible new subscribers. Lifetime has no free trial or automatic renewal. Subscriptions renew automatically unless cancelled at least 24 hours before the end of the current period. Manage or cancel anytime in your Apple Account settings.
