Ratings and reviews

EDIT 2024/1/3: Nice calculator. (1) Pressing 1/x should immediately return the value of 1/current answer or 1/current input, without any further input from the user. (2) The +/- button should always change the sign of whatever value is currently displayed, whether that value is the result of a calculation or user input. Pressing +/- should not trigger the start of a new line and a completely new calculation that starts with zero. These issues have not actually been addressed.

What can I say? A scientific calculator that works well. Buttons are responsive. Most used functions are visible, and those that aren't, can be easily accessed. The layout is also easy on the eyes and keys are easy to read. The history feature is nice to see, eapecially if you need to look at old calculations you've done. Also, I like how you can adjust the haptic feedback in small amounts. This sure beats Googles ugly, clunky and bare bones calculator app. Oh man that thing's an eyesore.

An incredible amount of thought must have gone into this. The layout and feature set is fantastic. Multiple values can be saved to memory. The running ticker allow you to click on previous values and add them to your current equation. If all you want is a basic calculator, the basic mode hass all if the features I wanted in one calculator but couldn't find. The memory and ticker (tape) add a ton of value to the basic calculator too.

What's new

- Improved overall error handling.
- Added specific error types including undefined, infinite, etc.
- Equation errors are now highlighted in various ways depending on their type.
- Other minor improvements and fixes.
