Thank you!!!!


I have been waiting for an iOS5 compatible version. I was starting to think the app had been abandoned. If this app is as good as the first one, it deserves 5 stars!!! & you can't beat free!!

The best timer!

workout freak!!!

Finally a free timer that you can save your work outs on!!!!

So fare the best one out there!!!!



Just what I needed! Been looking for something like this to do a lot of circuits with many intervals in one go. Wonderful customization. Beats out any paid apps out there.
