Panecal is a scientific calculator app that allows you to display and modify formulas. It allows you to enter formulas while checking them, which prevents you from typing incorrectly or making calculation errors. It is also possible to reuse past formulas and use variable memory to change only certain values to calculate them.
 The display shows the cursor, and you can tap or press the arrow keys to quickly navigate to where you want to edit. It has a powerful, flexible and intuitive user interface with support for swiping to scroll through formulas and long-tap to copy and paste.
- Re-calculation by using past formula
- Easy editing by using a cursor operation and swipe the screen
- Copy and paste formulas text

Bugs seem to get fixed

I like this calculator, does what I need with a straightforward interface. Haven’t bought pro yet but I think I will.

I was reading in the pro version about bugs with 172! And 0^0=1

The former seems now fixed and the latter I don’t believe is a bug. The limit of x^x as x tends to 0 would seem correct as 1.

The behavior with reduced precision mentioned by another reviewer is annoying as it compounds numerical error. I would agree that if you set 2 decimal places the expectation is a display option NOT a calculation accuracy option. The non displayed precision should be available for subsequent calculations.

But overall so far I really like it hence 5 stars.

Efficient and easy to use

I appreciate the large and easy to read and use layout. It is so wonderful to have all calculations and functions visible, and awesome to be able to edit for corrections!

Thank you!
