Unreliable & Crashes

Just purchased this app for my MacBookAir. Manually added all my data from Period Tracker, an app I used on my iPhone but no longer have the iPhone. After hours of manually inputting data the app crashed and lost all my data. After a few more tries and backing up data periodically I finally got the data to remain. If yu want an app for iPhone go with Period Tracker, this app is not worth the money they charge.

ISSUES:
- Backup email can not be changed
- Icons can not be added to calendar
- App crashes periodically for no apparent reason
