The alarm app that forces heavy sleepers to wake up
Challenge Alarm forces you to actually wake up — solve a math puzzle, scan a QR code in another room, beat a maze, shake your phone, or recall a memory sequence before it'll stop ringing. Stack multiple challenges if you're a hopeless snoozer. 14+ challenge types, step + water tracking, offline-first, no account needed, works in 15+ languages. Built for heavy sleepers who've beaten every "smart" alarm out there. 2,000+ installs, 50+ reviews since launching in March — all organic.
