Nobrainrot is a focus app blocker for people who open Instagram without deciding to. Pick the apps that eat your day, tap once, and they stay locked until your session ends. People who keep a mode running for two weeks or more get back 2h 13m a day on average (Nobrainrot in-app data). HOW IT WORKS Choose the apps to block: social media, short video, games, anything that pulls you in. Start a session with one tap or put it on a schedule. Open a blocked app and you get a quiet block screen instead of the feed. PICK HOW STRICT YOU WANT IT Easy: stop any time, or take a break of up to 15 minutes and come back. Hardcore: no way out until the timer ends. Not even the emergency unlock can end it. Shift: use the Shift device, a small NFC puck sold separately. Your apps stay blocked until you tap your iPhone on it. Leave it in another room and doomscrolling turns into a walk. The Shift device is optional. The app works on its own. SCHEDULES THAT RUN THEMSELVES Block social media every weekday from 10:30 to 19:30, before bed or during study time. Set it once. STRICT MODE While a block is running you can't change the mode or delete the app. Future you will try. This stops them. STATS AND STREAKS See how much time you shifted today, set a daily goal and keep your streak alive. Share your offline time as a card, not your feed. FREE AND PRO The free plan includes 3 modes and 1 schedule. Nobrainrot Pro lifts those limits and adds the allow list. Nobrainrot Pro is an auto-renewable subscription, billed monthly or yearly to your Apple ID. It renews automatically unless cancelled at least 24 hours before the end of the current period. Manage or cancel any time in your App Store account settings.
