The best app there is for Interval / HIIT training, or even just training in general 🙌 Easy to use. Allows you to easily set rest between rounds, incorporate rest within the rounds (if doing HIIT, for example) and has options for warm-up and cool-down times. If you set it, it talks to you too, to let you know your next exercise. It's SO easy to use and does so much stuff that I'm honestly stumped that it hasn't yet been rated! I struggled to find an app that I liked using until this one! 🙂

Developer is pretty resposive to questions. Can stack exercises together to create own intervals, but can't edit those as easily as single set of exercises. But I don't know why last low impact set is cut off. Can also listen to music while app runs in background. App will lower music volume to let you know when sets change. But there's a bug at the end of workout that doesn't turn volume back up.
