## Most critical reviews (2 lowest-rated)

### 2/5 — Great idea and could be a diamond

*2014-09-15*

This is a decent app, but could be great. It's missing some decimal placement and there is no way to input radicals and keep radicals in the standard form. If this happens, it will be the best app for trig and pre-cal

### 3/5 — Ambiguous case fail

*2011-07-27*

This app doesn't properly deal with or explain the ambiguous case for finding angles that may be acute or obtuse.
