Extremely useful

It’s a very useful calculator. It has more specific things than I probably use, but it could be used in the future. I only got it because a YouTuber was very adamant about this type of kind of calculator and I got it because it actually is full.

It keeps popping this stupid rating thing up

This app is fine, it has a lot of features I don’t use. but annoyingly it keeps asking me to rate it. So, two stars.
