The seven short vibrations to your Ringly are your Out of Range notifications.
Out of Range notifications can be turned on and off from the Settings page of your Ringly App. The out of range notifications will alert you when your Ringly and phone have gone out of range of each other. For instance, if you get up from your desk to get some lunch, or leave the apartment to head to work. We hope you use this feature to make sure you don't leave your phone behind!
Bluetooth range, however, can be affected by a number of environmental factors, and if you find this feature not useful, or it is going off too much for your liking during the course of a day, feel free to turn it off from the Settings page of your Ringly App.
