Simple. Elegant. Useful.

Buckle is an amazing piece of hardware for classic watches. Love the concept and have backed it on Kickstarter. Really simple addition to all the watches and convert it to fitness tracker. UI for the app is simple, intuative and completely made "not to waste time" on meaningless features. Great product all around.
