brilliant but insane. It works great, but once I've started the timer it's impossible to go back and adjust the interval times, there's no 'settings' button, nothing, this is driving me insane, I might have to find another timer. Edit - I've found a way, I have to kill the app, open the app, and then press back button. Would be much easier if there was a settings button.

suggest moving the green control bar from the top and putting it in the bottom of the main screen which has empty space. this would be easier to see and reach with thumbs. I can send you a screenshot if that helps.

It's a great app, but it doesn't let you start the timer on the watch. In my case, I like to leave my phone in the locker so I can't use it.

Costs like a wing of a plane while does nothing. Can not save a single timer without a subscription.

Great, until I tried to add more intervals to a workout. It let me do this and only when I went to save did it inform me that I had to pay $7 for the privilege. Now, I don't mind premium features being paywalled. Devs have to make money too! But if you're going to do it, be upfront about it. Don't let users waste their time. I've bought the premium versions of apps before, and if I'd known the limits going in, I might have purchased this one. Instead, I'm uninstalling and finding something else.
