The app itself was pretty well done, besides being a little slow and crashing at times. It can be frustratingly slow to add data for good so basic that should be included automatically. But still, it was an OK app...
The update just erased my data, a months worth of painfully and patiently entered information.
Not a happy camper. If you are going to release an update do your homework before to make sure you are not going to mess with your early adepts!!!
