Tiny Coach - A tiny 3D coach for home workouts on iPhone and Apple Watch

Tiny Coach is a home workout app for short, equipment-free sessions on a mat. An animated 3D coach demonstrates every move while a voice coach calls out the cues, on iPhone or Apple Watch. 38 courses, 6–15 min each. Fully offline, no account needed.

AirAlarm - Wake at the end of your sleep cycle

AirAlarm turns your iPhone and AirPods into a gentler sleep alarm. Set a wake window, drift off with built-in sounds or your own media, and wake at the end of a 90-minute cycle. No Apple Watch, account, ads, analytics, or cloud sleep profile.
