Very good

Just downloaded because the Calculators I had ether didn't have fraction and or square root. This app has BOTH. I recommend if you need a calculator with both fraction and square root capabilities

Some guy sleeping ,


Exactly what I need, does fractions and square roots. Highly recommend.

Not worth it.

Only gives answers in decimal format. Not enough button options. Not very user friendly. Does not rotate with phone. $$$ wasted.
