Love this app! It deserves to be at the top of the search. Slick UI, lovely design and features you never thought you need until you realise you do. 5 Stars. Wonderful. 👏 🎉

Best calculator app for most calculations. Has everything you need really unless you are doing PhD in combined mathematics and biochemistry then maybe you might need a more complex calculator but for most calculations it's all you need.

★★★★★ — Alvin Mugambi

Amazing app for a calculation nerd like me. I mostly use it for percentages and currencies and it makes these tasks a breeze. Totally worth full purchase price to go ad free and support the developers. A++ 11/10.

In a world of oversimplified and useless apps, this one has every tool you can ever need. Been using this app for a few years now. And it's fantastic. It's a calculator complete with more advanced functions, conversion tools, and so much more. It's fantastic. Please don't change it in any way to remove any of it's functions or usefulness.
