1. Even though it's packed with so many functions, you'll get used to it in no time! Best help document as well! I'm so happy and thankful! This is the only calculator you'll ever need.Equals doesn't repeat the last operator and operand as it does in many simple calculators.
2. It has an expression entry mode which is the opposite of normal calculator entry, this mode is required to use the complex number features and I found it very awkward and time wasting when the rest of the calculator is set for normal algebraic entry.This has it all! A simple calculator that shows the complete equation.
3. It does seem to update often which is annoying and it has some 'features' which you may find useless or annoying such as very high precision (100 digits) calculations which make it less responsive and are useless in a handheld calculator.
4. The demos scientific calculator doesn't have all the rounding functions, nor can it save, the graphing one can but not without an account.
5. Besides that minor complaint, if you're wondering which sci calc app to get, you won't go wrong with this one.This is a very nicely skinned calculator with a wide variety of functions.
6. There was also no obvious way to pay for the app to remove the ads - the full screen was a calculator and I didn't see any way to see how much it would cost to purchase the app or a method to do so once it was installed.Fantastic sci calculator.
7. Seems like a really basic thing to be able to repeat an operation on a previous answer in any number base.Like the calculator.
8. Most themes are unusable (the text and button labels are not visible), and the rest are very low contrast, either the results screen or the buttons are super hard to read.honestly a great app, probably the best in the app store.
9. Oh, let me mention the layout for tablets is an awesome full-blown calculator! The keyboard layout makes good sense.
10. A scientific calculator that allows many functions.
11. The graphing part of the calculator is okay, it would be nice if there were fields to set the camera position though.
