The round and the time left stay on the Lock Screen and in the Dynamic Island, and the bell sounds anyway. Does it work offline? Yes, completely. No account and no sign-up either. Boxing only, or other sports too? Any round or interval work: boxing, MMA, Muay Thai, kickboxing, BJJ, HIIT, Tabata, EMOM, AMRAP, circuits. Can I set my own round and rest times? Yes, in five-second steps, along with the number of rounds and the warning before the end of the round. Does it need an Apple Watch? No. If you have one you can start, pause and skip from your wrist, but the app works on the iPhone by itself. Will it play over my music? Yes. The bell and the voice cues come in over whatever you are listening to. Terms of Use: https://ghapps1.wordpress.com/terms-condition/ Privacy Policy: https://ghapps1.wordpress.com/privacy-policy/
