Chalarmy is an iPhone alarm that won't shut up until you finish a small task. Solve a few sums. Walk twenty steps. Scan the QR code you stuck on the fridge last night. The snooze button stops being an option, because it isn't there.
I built it because I kept turning my own alarm off in my sleep, then waking up at ten. The other apps that promised to fix this were full of ads, paywalls, and onboarding screens trying to sell me a sleep coach. So, this one.
Free includes the alarm and easy or medium math. A premium unlock adds the harder math, the rest of the challenges, and saved profiles. No ads in either.
