### 1/5 — Waste of time

*2014-09-24*

Terrible, doesn't work, don't waste your time!

### 2/5 — What happened?!

*2013-07-24*

A revision or two ago this app stopped working on our iPad 1. One can enter data but no calculations take place (and no re-calc button appears to force same). The <return> key does not cause any re-calculation either. Not sure what happened but if not cured in a version or two it will deleted. Too bad. It was a 5-star IMHO.
