Trainer suggestion if: you have aluminum rims or brake surface that don't have a steel pin connecting them.
Result: Super quiet, no need to change tire, absolutely no wear on tire, made in Canada, awesome company, ownership, customer service, etc.

Original question: They will be coming out with a new app in the future that will be much prettier and have many more features. (They delivered kickstarter on time! so this is believable.) But for now the current version is a very basic app that displays power (instant, various averages, workout average) and cadence, speed, and diagnostics on two separate screens for use with their trainer via Bluetooth or ANT+ similar to a cycle computer - basic info that you'd want on your dash. Very functional.
