Make your distracting apps boot up like heavy video games, so you don't accidentally start scrolling whenever you have a second to spare. When you tap TikTok, Instagram, Reddit, or any app you choose, Boot Up intercepts the launch and runs a boot sequence. A loading bar. Compile messages. A few seconds of nothing. Break the habit of opening addictive apps instantly. How it works: - Reaching for TikTok at breakfast You unlock your phone and tap the icon out of habit. Instead of an endless scroll, you get a 30 second Boot Up screen. What might've turned into an 15 minute accidental doomscroll is now a conscious decision to boot up your app. - Doomscrolling in bed You open Reddit at 11pm "just to check." Reddit starts booting up. You decide you are too tired before it finishes booting up. You lock the phone and go to sleep. - Actual break time You actually have a moment to scroll. You wait for Instagram to boot up and start your scroll. After 10 minutes your grace period is reached and Boot Up shuts down Instagram. You are always in control: - Pick exactly which apps to lock - Set the boot duration from 5 seconds to 5 minutes - Set the grace period, how long the app stays open after unlocking - Optional boot time and grace period per app What Boot Up is not: - Not a subscription. It is free, forever. No premium tier, no trial. - Not a tracker. Zero analytics. No network requests. Your app choices never leave your phone. - Not a guilt machine. No streaks. No shame. No motivational quotes. Just friction. - Not closed source. Source code is on GitHub. Instead of relying on willpower every time you pick up your phone, add a few seconds of friction so distraction becomes the harder choice. Set it up once. Tap the icon. Wait through the boot. Feel better about your scroll. github.com/eliguzz/BootUp
