Comments on TechCalc Scientific Calculator for Android

★★★★★ Xuan Zheng · Aug 27, 2021

The only calc app you will ever be needed, For the past 10 years I have used various calc apps and finally settled on this, enough said how good this one is.

★★★★★ william kazungu · Jul 4, 2022

Thank you for the App, I have used it for many years. One bug or is it something to do with my phone Itel A16 Plus? The Submit button on creating Custom Formulas on the Quick Formula screen seems not to be working even after following all the instructions, i.e. one or two characters for the formula variable items and at least one an alphabet. I used to save well on my X-tigi A4 phone years ago and the resulting Formula could appear at the end of the pre-programmed Quick formula list. Updated.

★★★★★ Duncan Porter · Sep 25, 2022

Excellent calculator for any specialty application! Includes unit conversions and reference information. The most complete calculator I've ever used.

★★★★★ Tarekegn · Jun 7, 2021

Excellent: it performs almost all mathematical, physics, statistical, engineering and lots of other calculations as well. Great app!

★★★★★ Christopher Bell · Jul 5, 2024

This is a scientific calculator app not a graphic calculator! Does the task quite well.

★★★★★ Brian Biby · Dec 12, 2025

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!!!

★☆☆☆☆ Nitin Kumar Jain · Dec 19, 2025

Binary/ hex converter is not working after last update

★☆☆☆☆ David Judge · Apr 25, 2026

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.
