Inspired by Project Euler, Factorial Calculator can calculate 10000! and above in very short time. This app uses completely difference algorithm (logic) to find the factorial compared to usual algorithm used to calculate small factorials.

It also shows the number of digits in the factorial along with the sum of individual digits.On More page, the number of individual digits can also be viewed. Uses latest Android components to deliver seamless experience.

It was fun to implement and learn about Jetpack and parallelism. Don't forget to rate the app. :)
