A quick and easy race registration app

I am an active runner and has long wanted an app where I can quickly register information about the course, with a few simple clicks. An app that only register where the course took place, distance and the time I spent. As well as an opportunity for a short note or summary of the race, using keywords. This I want to quick post just after the finish and it must be searchable for later.

Some developers who would like to join in the development of this app?
