Polar is another brand that has their own watch software. They tried Android in one model, but they too had problems with battery life. Unfortunately Suunto is moving to the app only direction too with the numbered sport watch series. Ambit and Spartan required an app for synchronization too but at least there was a desktop option. One thing that Garmin got right in their old models was that you could just plug the watch into computer and it would show up as USB drive with GPS tracks as files.
