### 1/5 — Crashing

*2023-04-15*

Constantly crashes a few seconds after launching.

### 1/5 — Won’t even stay open!

*2020-02-29, version 1.1.0*

I don’t even know if it works since the app won’t even stay open long enough.

### 2/5 — It doesn’t work as best as I had hoped.....

*2018-11-28, version 1.1.0*

I like the idea of this app a lot! It is really easy to use but my school provides notebooks for us to use for math and they have graphing paper inside of them and when I use this calculator(even if I make the writing as dark as I can) all it reads is tons of 1s so it won’t work for me.....but it works ok on regular paper with no lines but sometimes it has a hard time reading my work and I try to right as neatly as possible and with as much light as I can but still it sometimes doesn’t work! Great idea but needs some fixes.
