Sometimes unreliable

When it works, it works fine, but it’s sometimes unreliable. There seem to be some programming issues. For example, sometimes it starts the music when I start the warmup and sometimes it doesn’t. I’ve had it crash mid-run; this is really annoying when you’re waiting for it to tell you to stop running (or start running)! And, for the love of Pete, don’t lock the device while this is running! (It won’t tell you anything.) It’s basically a good app, it just needs some updated programming.
