How Long? How Often?

Just a simple app to help calculate how long it will take you to complete something, or how often you will need to do it to complete on time.

For example, I want to watch all of the current Game of Thrones episodes before the new season starts. It will tell you how many a week you need to watch to be done in time.

Or, I'm working through an online course. It has a number of lectures, I've watched 20 so far in 4 weeks, there are 154 in total, how long will it take me at this pace?

All done in a aesthetically pleasing Material Design!
