Hello, I'm teaching myself the "Ionic" framework for fun and wrote an app to calculate the coding time for a problem in a Topcoder contest, based on points scored. There used to be some great websites for Topcoder utilities like this, but anyway, here is my small offering:
Ionic is intended for mobile apps, so it will look best on a phone.
There is one bug which may amuse this audience to find: for a certain input, it shows a correct but wrongly formatted coding time. I'm sure there's more, so all suggestions and bug reports are appreciated.
Note, the app is of course free, but I plan to monetize it using the Reverse Knuth Model, meaning the first person to submit a bug report owes me $1, then the second owes me $2, the third owes me $4, and so on doubling each time.
I expect to retire soon!
