I have a dozen Android calculators just from searching for the right one for me. There are two I use on a regular basis, depending on what I'm doing. I didn't think this one would be any different than the great masses of existing calculators, but I was pleasantly surprised! Though the UI could use a major facelift, some of the displays present results in a great and efficient way. I've added NT Calculator to my daily use calculator list.

This application is very good, because it calculates numbers. Not only it does calculate, but also provides you with a few converters. If you want to have more converters, use the NT converter app. Also, the dark mode is nice. But it has problems: 1. The date selection dialog is all black, leading to dates being unreadable (black on black) 2. When calculating very large numbers, it gives you values like 3.16129E15. Thanks for fixing bug #3!
