### 1/5 — Bought it then couldn’t use it

*2020-09-20, version 2.2.0*

Really liked it but wanted more options and no ads so figured I would buy it...when I did that the -,+ & = lines got pushed off the bottom of the app with no way to scroll down to use them or zoom out at all, the ads don’t seem to be gone and so it’s now unusable. If I could give negative stars I would.

### 1/5 — Craptastic

*2019-07-10, version 1.0.1*

If you want a big redirect to the App Store to download a game as soon as you try to test this app, this is the app for you.

### 2/5 — Can do BODMAS

*2017-07-14*

and that's the kind of thing I can say about it. User interface poorly laid out, you cannot use speech alone, ads are far too intrusive.

### 1/5 — Bad apps

*2017-06-06*

8^5 pronounce 8 cap 5 instead of proper 8 to the power of 5
Sin = Sine, not sinus, unless sinusoidal function
Simple trigonometry needs to get paid apps?
