Comments on TechCalc Scientific Calculator for Android
★★★★★Francois vzb· Dec 20, 2022
As an engineer and a scientist, this is the most amazing calculator app that I have ever seen or used; and it is all free of charge, with even an easy and free way to remove adds. This calculator is a transformer, that you can morph at will into a variety of many top-notch different specialized calculators, scientific, programmer's, financial, etc. with an embedded reference base of data, constants, formulas etc. in areas as diverse as e.g. mathematics, physics, chemistry, astronomy and finance.

I'm using this calculator very often.... Very nicely design. But if app has option to use USER DEFINED CONSTANTS or VARIABLES in QUICK FORMULA then it is more useful and user-friendly. Hope to see such implementation in the future.

I am an engineer and have used this calculator for years. I have tried others but come back to this one every time as its look, feel, and great extra features make it just #1!!!

I want a scientific calculator but not always scientific notation displayed
★☆☆☆☆Rae Cooke· Dec 6, 2025
I paid for this app as I rated it the best calculator for my requirements. Unfortunately after losing my phone and subsequent purchase of a new one, I lost the paid version of the app. As I no longer used the app as frequently I settled for using the free version. I was happy to put up with the ads as they were not too intrusive until now when they have started displaying pornographic images across the top of the screen. This is the second app that I have removed recently for the same issue.
