Your phone, but boring on purpose. Friction Frog puts one slow breath between you and the apps that waste your day, then turns the addicting ones black & white so they're less stimulating. The blocking and grayscale are free forever. -How it works- Breathe before you scroll: - Pick the apps you want to slow down (TikTok, Instagram, YouTube, etc.). Try to open one and Friction Frog asks you to pause for a short breathing exercise first. You get a few minutes, then it locks again. Just enough friction to break the autopilot. Grayscale, your way: Color is what makes the scroll so hard to put down. Friction Frog walks you through two setups: - Whole phone in grayscale, with color exceptions for the apps you need (Photos, Camera, Maps). - Or keep your phone in color and gray out only the addicting apps. No more triple-tapping the side button and forgetting to switch it back. Limits that fit you: - Set your own time window per app, one app's "quick check" might be 1 minute, another's 30. You decide. Why Friction Frog: - Truly free. Multi-app blocking and every grayscale feature are free forever. - Reliable. Built to just work, every time. No mystery failures, no easy bypasses. - On your side. No ads, no exploitation. The business isn't built on keeping you hooked. Built for: - People trying to get better Made by one person who had the same problem and used this system to fix it for himself (Hi. That's me, Will.). Download the app, take a breath, and get a little of your day back.

Block the apps you can't put down. Justop is a screen time app blocker that hides the apps, categories and websites you choose, either during the hours you set or once you've used them enough for the day. Once a block starts, there's no snoozing it. HOW IT WORKS • Set a schedule (days + time window) or a daily time limit (an amount of time per day). • Choose the apps, categories or websites to block. • A schedule shields them for the window you set. A time limit shields them once you hit your daily amount, until the next day. NO EASY WAY OUT A running block can't be edited, turned off or deleted. If you really need back in early, the unlock session takes four hours and you have to stay on the unlock screen the whole time. Leave the app and the timer starts over. VACATION MODE Taking a real break? Vacation mode lifts every block for 24 hours, up to three times a month. It can't be ended early. PRIVATE BY DESIGN No account, no analytics, no ads, no third-party SDKs. Justop makes no network requests. iOS hands it opaque tokens, so it never learns which apps you picked. PRICING Free for 2 days. After that, a one-time purchase unlocks Justop for good. No subscription. Justop uses Apple's Screen Time frameworks. iOS always lets you turn off its Screen Time access in Settings or delete the app, which lifts every block. Requires iOS 16 or later. Justop: the app blocker, screen time limiter and focus app for people who are done negotiating with themselves.
