Needed a free app. This app is beautiful, easy, and free. There’s some tweaks that could make things better, but I’ve been using it for yoga and calisthenics for the past week and it’s great! Thanks so much to the developer :)

Best interval app

This app is simple and easy to setup and use. I love that they update it, just received the update that the voice command gives you an encouraging half way update!
