This is the best calculator for the iPad and iPhone ever! Its compact and useful features make me less hassled to go online to check my solving or graphs. Must get the 4.99 upgrade! At first, the scientific calculator isn't that seemingly a strong lure, but they 4.99 upgrade makes thing thing shine and it's awesome! Strongly recommended for middle school, high school, college, or even real world scientists!!

It's ok but with a huge flaw

Maybe I haven't figured out how to work it fully, but...
I HATE that once I have found an answer, hitting the equals, I can't do an operation on the answer without clearing and retyping the answer. I know I could use the parentheses to do the order of operations from the beginning, but there are times I want to see each calculation as I go. As a math teacher, I have never seen a calculator that after I hit equal puts the new operations into the original calculation. Big flaw :/

My Go to Calculator

When I got my iPad, I was annoyed that it didn't come with a calculator so I tried a few different apps and found that I like this one the best. In fact, I like it so much that I now use it on my phone as well. It's a Great Calculator.
