Calculess Free is a calculator for iPad. It can process nested expressions.
See the whole expression as you type it. View your previous calculations and results above the current expression.
The free version includes information about my other apps.
A history view lets you look back over recent calculations.
Tap any previous calculation to substitute it into the current expression.
If you need to send yourself any results you can: easily export anything by email.
A 2nd key flips some buttons over to expose even more functions.
Evaluate complex expressions. Use parentheses liberally. The app will give you hints if you type something incorrect.
Designed to feel similar to a TI-82 or TI-86 calculator.
There is some extra room for more functions. Please contact me with things you'd find most useful.
