ConCalc Free Calculator

A free version of ConCalc (concurrent calculator). It does everything the paid version does except for saving your changes.

A very simple calculator that has a single unique feature over most others. It allows you to see multiple results simultaneously, even as you type a number. For example, you can use it to show unit conversions, sales commissions, multiple rate discounts, or any other concurrent calculation you're interested in.

Your own predefined calculations (which can be grouped in files) can include several functions (like sin, cos, min, max), and are automatically saved. Multiple calculator configurations/profiles including their related history list can be saved for quick reloading by name at a later time. The last calculator configuration loaded is remembered between program runs.

Press Menu/Help to get full details about how to use the app.

This app should work in most devices. However, if you encounter problems, first send me an email mentioning the specific device and Android version, and I should be able to fix it.

Thank you.
