DunDun is a focused squat counter built around motion sensors. It works with Apple Watch, iPhone, or even AirPods — using real-time motion data to detect squats without manual tapping or camera tracking. Designed for quick home or gym workouts, the interface stays minimal and distraction-free. No ads, no complicated setup — just open and start training. Built by the developer behind YaoYao, with years of experience designing for watchOS.

Tooboo is an outdoor navigation app built primarily for Apple Watch. While most route apps rely on the phone, Tooboo runs independently on the watch with a lightweight vector map engine. Hikers and cyclists can navigate without constantly pulling out their phone. Designed around small-screen clarity, battery balance, and deep HealthKit integration. No ads. No unnecessary data collection. Built by the developer behind YaoYao, featured 90+ times on the App Store.
