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.

The best feature is the "Ans" button which was missing from top calculators in the store. UI is better compared to many other high rated apps. App is light weight. ### 5/5 — Best calculator with history, but with suggestions *2013-05-03, version 1.0* Best calculator app with calculation history, even allowing you to copy/paste paste calculations for entering a new revised line, and allowing emailing of calculation history to yourself. However, would be better if result was show to right of equation for more compact history, like the "Math Sheet" app, and if could choose to Copy to Clipboard the equation or equation + result or history of all calculations (or select single term and adjust selection range) from long tap context menu, instead of only just tap to insert. Also, would be better if allowed inline editing and deleting of specific past calculation lines from history. ### 3/5 — Trig works *2012-06-24, version 1.0* You need to change settings to have angles it degrees from radians for trig to function as you expect. ### 4/5 — Good but... *2011-10-18, version 1.0* This calculator is great for everything except inverse trig functions.
