Gear alerts
My devices often run out of battery and the more I acquire the harder it is to track their charge. Many don't have screens or a way to report current charge. Could ST gear tracking be used to provide an easy and simple counter for time used since last reset? Notifications could then be configured by the user.
For example, I always use my scosche rhythm optical hr monitor. I could auto populate this in the gear section for all running activities. On the activity page, the device could be shown with a 'time used since reset' displayed, and a simple 'reset timer' button. On the gear page, I could set a threshold that generates a notification when the timer goes above a given value and I therefore get promoted to charge it.
This could be used for loads of devices - Bluetooth headphones, my runscribe pods etc etc
