### 1/5 — Don't wast the money

*2017-03-06*

App works alright. The pre-loaded data base is so so. Fine for spherical, ball bearings, and tapered roller bearings. All the info in this app can be found online... for free. The skf app also has a bearing frequency fault calculator... for free! Works, but not worth 5 bucks.

### 1/5 — Very bad

*2017-02-04*

Vary bad application, not useful.

### 5/5 — Simple and handy

*2012-03-21*

great reference tool
