### 1/5 — Idea is good, execution not so much

*2021-09-08*

Two of the three main buttons calculate around the wrong way. Numbers are missing in the display message in one of the calculations. There is no in app alarm - instead it tells you what time to set your alarm. There are way too many ads - ie after every time you click on anything. And you can’t get help from within the app as the feedback function doesn’t work.

### 1/5 — This is bad

*2021-07-30*

This is bad because whatever my timer like 6:00 like app kick me out this is bad
