I bought this so I could take notes in my notebook and it literally has like 60 formulas on it. There are so many more that they could add and it is not worth the $.99 there are different apps that cost the same amount and offer so many more formulas.

Great!

It serves my purpose of just wanting an app with consolidated Mathematical formulas for quick review when waiting around. The examples in how to apply each formula make it useful.

A handy reference.

This app is what I just needed and wanna thx the producer about inventing this app, it's the best and helps a lot

The formula examples are excellent for plug. And chug, but for spatial reasoning and understanding the concept for applying a formula could be done too. One of my favor tissue the story of the triangle.

Very easy to use

Good content but it needs to be patched. There's a bug where the screen won't turn and the side bar covers the notepad with the formulas... I can't see what I paid to see

Promising app has major problems which I attribute to lack of support for rez on older iPads. Virtually unreadable, unusable because of missing or overlapped text. Refuses to go into landscape mode, which might have fixed part of the problem. Wait for the fix before you buy on iPad 2. Can't speak for newer tablets.

I had a lot of trouble with using this on my iPad. It didn't rotate and half the screen was missing. There was no instruction and I couldn't get rid if the index. These rendered this almost worthless
