Is there a smartwatch the checks all of these boxes? Must haves: Android 2.0 HR sensor ~13mm or less thick Highly desirable: Standalone gps Non proprietary straps, interchangeable Battery life: as long as a full days use I'm fine The LG sport watch has the features I want, but it is thick and the watch straps make it a one trick pony. I'm giving the 360 sport a trial run but I would like more updated hardware. I also tried the gear sport. Great hardware but the software is sub par. Perfect watch would be the gear sport running Android, does that exist?
