Normally I'd have to learn how to use an electronic stopwatch and I'd have to do math to figure out the times of all the runners but this app makes it really simple with all the timers available. The additional features they have are also very convenient to use and I never would of thought of how useful they would be if I never had them.
Great business tool

I work from home, and often on several projects at a time. This is an amazing tool to help me track my time each day for billing.

Great but Tanks Battery
MrsFireMom
There’s no better option, but it absolutely tanks the battery in newer phones/iOS. Every release gets worse. I’ve used the app for years and wanted to find a better option for this season due to the fact that I can’t make it through a meet due to this app sucking the battery juice up. But nothing compares. Ugh.
