WARNING: DONT USE
Im writing this review after losing 3,000 contacts and the $2 for this terrible app. I started with the free version. When I lost my phone, thought I was saved. After reinstalling the app tried the back up ... and ohhh, it crashed during the contact import! Since I had over 3000 contacts I decided to pay for the "robust full version" and .... Ohhh!! Crashed again!! Even worse, the full paid app didnt recognize the backup files from TTY he light version. So it crashes. Bottom line: Screwed!! Stay away from this scam.
