MENDOU — Friction App Blocker

"Just one more time" — and suddenly it's been 30 minutes. MENDOU puts one small, annoying task in front of the apps you open without thinking. Solve some arithmetic, trace a kanji, tap numbers in order. It takes only a few seconds — but that friction is exactly what stops the mindless opens. ■ Why "just wait" stops working "Wait a few seconds" blockers stop working within weeks — your finger just pushes through. MENDOU doesn't make you wait. It gives you a different task each time, with the button in a different place each time, so your finger can't memorize its way past on autopilot. ■ What it does - Shows a task before a tempting app (open, or change your mind) - 4 task types + kanji tracing. You can't pick which appears — that's the point - Gets harder the more you open it that day - Set the interval until the next task per app (every time to 60 min) - See how often you changed your mind ■ Privacy Everything runs on your device. No ads, no account, no subscription. Your data never leaves your phone. ■ Pricing Restrict one app for free. A single one-time purchase unlocks unlimited apps. It's not a subscription. A little friction, right at the moment you reach for your phone. ■ About the Accessibility Service ▎ MENDOU uses Android's Accessibility Service. It is used only to detect the moment you open an app you have chosen to restrict, so it can show a task screen. It reads only which app is in the foreground — it never reads the content shown on your screen, such as text. It does not store or transmit any of this information; everything stays on your device. You enable the service yourself and can turn it off at any time.
