Works great as a timer for splitting sets etc

A great App, easy to navigate and set up, only issue i would say is it’s too quite so when you’ve got music on it doesn’t lower it to speak so sometimes I miss the finish of a set etc, hence the 3 stars but other than that I’ll keep using it.

Bait and bill

The underlying functionality is meh. Setting up a workout for the first time is a bit confusing and not super intuitive. But more than that the big problem I have is that it simply wouldn’t work past the first week (or about 3-4 workouts for me) without a subscription. This app wasn’t advertised as a “free trial”, but that’s what it is. I don’t have a problem with devs getting paid for their work, but an app that’s advertised as “free” should actually work for more than a couple days before a subscription is required. A basic interval timer shouldn’t require a recurring monthly invoice IMO. Will be deleting the app today.
