Better than Apple's "Screen Time" feature, VisionLock helps you understand why you scroll, and adds friction exactly where your thumb runs on autopilot. 4 hours. That's the average time people spend on their phone today, often without even realizing it. Most blockers just ask "which apps do you want to block?" in 30 seconds. VisionLock starts differently: a short diagnostic to identify your real trigger (boredom, anxiety, a nighttime habit, social comparison...), then builds your Vision: what you want to protect with the time you win back. How it works Instead of a hard wall, VisionLock adds friction before you open the apps that waste your time: a countdown that gets longer every time you reopen the app during the day. This friction actually works. A field study (Grüning et al., PNAS 2023) found that a few seconds of delay reduced compulsive app-opening attempts by 37% over 6 weeks. Your Vision, always in view Before you open a distracting app, VisionLock shows you your Vision: the photos and sentences that represent what you actually want. A quiet reminder, at the right moment, not guilt-tripping. Features • Session blocking with progressive friction on the apps you choose • Usage reminders at a custom interval • Compulsive reopening (relapse) detection, with a one-time extension option • Fully customizable Night / Work schedules (hours, days) • Website blocking by domain • Personal Vision board: photos and sentences shown before opening apps • Weekly Vision Report: the time you protected this week • An honest streak that tracks daily consistency • Emergency unlock with a written reason, limited per month • Native integration with iOS Screen Time Free forever Core blocking will never be paywalled: one session block, reminders, one scheduled block, one Vision, free, with no time limit. VisionLock Plus unlocks Website blocking, multiple schedules and rules running at once, unlimited apps per block, unlimited Visions. A subscription is required to access all features, including widgets, themes, reminders, and sharing. Subscription details and pricing are available within the app. Privacy policy: https://visionlock.vercel.app/privacy Terms of use: https://visionlock.vercel.app/terms EULA: https://apple.com/legal/internet-services/itunes/dev/stdeula
