All my old Facebook contacts from over the years had been syncing into my contacts, and this saved so much time from going into each contact to delete their birthday. Makes my calendar look much more clean.

### 5/5 — Works!

### 1/5 — Useless. Rip off.

*2019-03-20*

I have a ton of birthday entries thx to Facebook. The app doesn’t even detect all of them. Do not buy this app.
