They don't give you the correct answers ### 5/5 — Actually good ! *2013-11-11, version 1.0* This app is actually neat and well functioning despite the bad reviews. 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. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
