Dopamine Killer

YouTube Shorts, Reels, endless surfing... Suddenly 30 minutes are gone? Dopamine Killer is a focus-alert app that wins your time back from Shorts and social apps. It doesn't just beep on a timer — it detects the moment you open a distracting app, and if you keep going, it locks the app for you. ■ Key Features • Distraction detection — the moment you open YouTube, Instagram or any app you picked • App locking — go over your limit and the app is shielded (hold: instant to 60 min) • Force-quitting won't save you — kill the app and it locks right back • Trigger-only mode — silent all day, alerts only while you're on a distracting app • Grace time — up to 1-15 minutes of use before it says anything • Reminders every 1-30 minutes, on your own rhythm • Dynamic Island · live widget — elapsed time and interval at a glance • Comeback stats — honestly shows how many reminders you ignored and minutes you burned • Shortcuts automation — starts itself when a chosen app opens • Fully offline · No login · No data collection ■ Made for you if - One Short turns into 30 lost minutes - You open social apps mid-study without realizing - You need a system, not more willpower Available in English, Korean, Japanese and Simplified Chinese. Annoying, but not too much. That's Dopamine Killer.
