I enjoy using this app in theory. Really beautiful design, unique features, and while the UI could definitely be simplified, it's still a very good app. However, after a simple mistake while creating my account, I cannot get the oIS app to sync with my account, period. I've had numerous interactions with customer support, and followed their suggestions to a T, however this basic issue still has yet to be fixed by TrackingTime Support - rendering the iOS app completely useless. My last support request was over two weeks ago, and this particular issue has been a problem since day one (several months ago at this point) and when I contact them they inform me that they're STILL working on a fix. I've simply run out of patience, and faith that these guys actually know how to fix their own software. If somebody from TT is able to fix this issue, I'd gladly change my review. Till then, I'll keep waiting...but at this point I wouldn't recommend TrackingTime to anyone.
