Comments on Ultimate Calculator for Android

★★★★★ Lex Bolkesteijn PH2LB · May 26, 2019

Great tool for the serious ham radio operator or rf/electronics engineer. Would like to see a light theme though because environment light.

★★★★★ Irian MonBel · Feb 12, 2018

Awesome calculator. It has absolutely everything (and more!) a hobbyist electronic and Arduino user can need.

★★★★☆ Duane Matthes · Jan 19, 2026

Almost perfect. I would have given five stars if the calculator portion of the app had a little bit more functionality for mathematics. It needs a few more scientific functions to be truly useful for most engineering calculations. Why no radical key? Otherwise, the app is flawless, and should honestly cost a lot more than what I paid for it. Good stuff all around. Buy it!

★★★★☆ A Google user · Oct 3, 2018

Love the App, Great developer, just need more conversions support adding like weight's, fluids, etc., there's also a few niggley bugs about like formulation calculation interaction buttons appear to swap designations as you enter your sum choices, that then fail to reinstate themselves back to their correct default states after your finished sum when hit clear button. I've found these across different parts of the calculator overall, but I have not done a detailed itinerary of them.

★★☆☆☆ Andrew Tasidjawa · Jan 19, 2019

I'm using homophone, when I select search, favorite, DC circuit and reference the app is off/exit. Please fix it.
