Your phone won't stop you. Your friends will. Doomlock locks the apps eating your time and only your crew can let you back in. Need five minutes back? Ask. Whoever answers first decides — how long, or not at all. Answer fast for your own crew and you earn Keys, redeemable for a no-questions-asked unlock the next time you're the one who's locked. No willpower required. No shame either — just people who actually care whether you get anything done today. How it works • Lock the apps wrecking your focus • Ask your crew for time back when you really need it • First to respond decides — approve, deny, or cut the ask down • Answer fast and earn Keys of your own • Watch the leaderboard — least scroll wins, fastest hands win What Doomlock never does Doomlock can't see which apps you use or how — your app selections never leave your phone. Your crew sees a request, never your history. Built for people who've tried the willpower thing solo and are done pretending it works.
