This is a unique calculator, you could call on it on many Apps without more switching, just in your input method.

Based on four fundamental operations, I add more functions, including exponential, logarithm, trigonometry, constant, random number etc., which could cater to almost all your requires.

This is an independent calculator and I developed it in my spare time, let me know if you have have any advices at [email protected]
