From the the makers of nothing comes TRAIL GENIUS!!!!!1 This app is in an alpha stage so don't judge too much yet. I basically did this app to this point in a month. I am switching gears to start doing the cloud aspect of it. There will be a lot of new features coming once the cloud is up and working. A lot of the basic features like exporting to GPX and caching local tiles will be taken care of. This is mainly up on the market right so my tester can download it easily and also so I can show possible employers it because I am looking for a job. So hire me!
Key points about this app so far are:
Unlimited scalability in trail data. An absurd amount of visible trails will be able to be shown at the same time without bogging down the phone.
Collection that holds trail point data is all O(1) or O(N) for relational operations. Same collection will be used on cloud.
Intelligent algorithm for collecting trail data does not blow up your trail when the accuracy is not very good.
