Complicated, over cooked mobile exp. is a big letdown.
Id love to give this lock a little more love. The lock is sturdy. The Bluetooth sync works great.The problem is the UX. It is so complex. I spend 10 mins at the gym trying to make it lock. One time I thought it was locked, but it wasn't.How hard is it to have an app that has a locked image on it, you hit a button and it unlocks and shows that on the display.Too many features and different user paths, worrying about web based profiles and locker mode - they forgot the basic principle. I wish I'd bought another brand and currently force myself to use it over a traditional lock just coz I spent $$ on it.Design your app like Apple did the iPod. One button that clearly makes it lock and unlock. Forget the other stuff for now.
Thank you for your feedback
