The Time Tracker IQ app requires internet connection to function. That means you must keep active the Bluetooth link between your phone and your watch.
The connection status icon provides information about the connectivity.
There are four possible status:
Invalid key (orange icon): That means the Bluetooth connection is active but you must link your app.
Sincronizing (blinking blue icon): the app is sending and receiving data.
Standby (green icon): the app is waiting for the next synchronization cycle.
The app syncs with the website every 10 minutes, but it will be immediate
when you start the app, after you save a time entry, or when you force it using the "online sync" menu option (the force option is not available on Fitbit and Garmin Forerunner devices).
