Customer Reviews

Works really well

When I first bought this app it seemed a little quirky and I had a hard time understanding it, but this app really does work, and it’s super simple once you play around with it awhile. Highly recommended if you need to track hours on multiple projects!

Does Not Work

I tried to put entries into this program and it automatically changes them to an incorrect number. This program has bugs and does not work. It is garbage.
