### 3/5 — It's OK.

*2016-08-25*

I have a cm100 (from the eighties) and its a fantastic calculator for programmers. Mine still worked perfectly until the other day when the "A" key fell off. I was hoping this would be a good replacement. Its just OK. One of the most annoying things is that when you push the HEX, BIN, OCT keys it doesn't put populate the display with the leading zeros. For some reason that really bugs me. I also enjoy emulators that go the extra mile. For instance, the cm100 puts a little +,-,* etc on the right hand side of the screen when using those. This doesn't, it has a really annoying text box at the top which looks awful and ruins the whole feel of the app.

### 5/5 — Amazing Calculator

### 5/5 — An awesome app for CM-100 calculator fans!

*2019-11-19*

Brilliant to have this app available. The CM-100 is an excellent and unique computer math calculator ideal for assembly programmers and retro computer enthusiasts, and this app means anyone with an iPhone can enjoy having one readily available for use in their work or just to play around. 5 stars!

### 5/5 — Does not work with IOS 12
