Then you could have pace clock on one side and workout on the other side. That would make it perfect me. ### 5/5 — Does it work with Apple TV?? *2022-01-26, version 1.1.0* Does the app work with Apple TV?? Does not appear when searching. ### 1/5 — 止める事が出来ない *2021-06-01* 秒針を止める事が出来ないので、他の時計と合わせる事が出来ない。 **Developer response:** レビューいただき、誠にありがとうございます。現状の仕様では、分針/秒針は端末の時刻に一致させていることから、一時停止や任意の時刻での設定ができません。ご期待に沿えず申し訳ございません。今後の改修の参考とさせていただきます。 ### 4/5 — Simple, works well *2019-11-08, version 1.0.0* I put my phone in a dry bag/ case and hang it from block. This is very simple to use, works well enough and could be great with some tweaks like: - digital clock is hard to see. More contrast or allow changing the appearance - add a beep for start - use whole screen - make the interval marker bigger some way - or something like the clock app uses for timer display ## Frequently asked questions about Pool Clock ### What is Pool Clock used for?
