Very good calculator, all functions for Indian users specially commas after thousand & lakh 👍 only one import thing I'll suggest please display ANSWER WITHOUT clicking "is equal to" button e.g. If I type 5X3 it should automatically display 15 without having to click on = button, it's common in almost all other calc apps

Never liked the calculator that came with the phone. Found another app that I liked but it seems that updates over time began to make the app hang up as well as the phone. Stumbled on to this one by accident and I love it. It's smooth and the several different themes means there is one you will probably like. It is both a simple calculator and a trigonometry calculator. I couldn't ask for more.
