User reviews

Doesn’t work

GPS distance does not work, when editing and saving workouts it does not do the edits it stays stuck on what was there before

So much flexibility in configuration - Great support

There is so much flexibility and customization that you can build into your timers. Support is very responsive too.

Great! Constant updates

I would be happy enough with this as a phone app, but it’s the watch integration that makes it one of my all-time favourite apps, period. Use it every day for exercises as well as any time I need a stop watch – much more flexible and nicer UI than the built-in versions.

Indispensable

I’ve been using this app for at least seven years and it’s indispensable for training and other timing purposes. The customer support is also very good.

Good app

This app is getting better and better
