Unsupported App – Tabata! HD: 4 Minute Workout Challenge. Burn calories faster than ever! Review

An extremely well designed exercise app. Simple, fun to use. BUT the app is unsupported: one release in August 2014, no updates since then. The AUDIO DOES NOT WORK with iOS 8.3. Unhappily, sound cues are essential for an exercise app.
