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.

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.

Great at first, now it doesn’t work.

I purchased this app a couple of years ago and thought it was so awesome! The different calculators, the ease-of-use, the customizability of the calculators was fantastic! Now for some reason when I go into the app it automatically closes. I go into the app again, and again, and it just closes. It will not allow me to use the app at all. Originally the rating would have been five stars, but now as I cannot use the app I am regretful to have to rate it a one star. I hope somehow my issue can be resolved. I really love this app and would love to continue to use it.
