Arc cosine calculator

The steps make the equation way easy. I'm a bit upset that we can't openly see steps, however it's okay. Even though the camera function doesnt work, this app has really help me with my math problems.

Simplicity is key. My favorite feature is scanning the problem, super easy to use and great quality, but the problem is you just need to buy a premium or to log in there app just to know the "solution" of how did they get the answer :(.

I use it all the time to do my math homework in college, the only critique I would make is that the explanations aren't free. Right when I'm getting frustrated this app helps me to find the answers im looking for. It is fun and easy to use the camera is a little blurry when you first scan it but then it auto focuses.
