Customer Reviews

Great free option for a scientific calculator

This doesn't get super fancy, but it has nearly everything I want, and it's free. One can calculate log and ln, express numbers in scientific notation, calculate nth power, nth root in addition to square and cube roots.

I am a mere chemist so if you're an engineer, statistician or some heavy duty financial type, you may be better served by another app, most likely a paid one.

I would have given it 5 stars but for the ads that pop up. But you can get rid of them quickly so it's not so bad.

Idea for the Display

This is a fantastic all-in-one calculator. For me, who is right handed, trying to input data and see it on the white page is very difficult. My right hand covers the white page. My idea would place the white page on the left side of the screen. You could have a button for left-handed and right-hand users.

Use all the time!

This calculator app does it all, from simple arithmetic to metric conversions to trig & calculus. Mostly, I use it to balance my check book, but, every once in a while, there's orbital mechanics equations ...
