Can’t use while locked
UPDATE: developer says that no app can do this, but the other timer I’ve downloaded does it just fine. I’m sure there’s probably a legitimate thing that’s making it difficult to implement that but I will continue using my other timer since it does the job.
Waste of Money
Don’t waste your time or money
Use the timer in your phone it’s the same thing but free.
Response from developer
Hi Mack. In circuit training you add exercises by increasing the number of time intervals. In the app you can do that by tapping "Sets +" button on the settings screen. This is a core functionality of the app and is available for free. It is not possible to achieve this type of multiple interval countdown using built-in iOS timer app. If anything’s still unclear you can contact us via links in the Support and Feedback section on the app’s settings screen.
Simple and effective
The App name says it all
