Draining battery

Works as advertised for the unlocking tough if your Mac goes to login screen it does not work. The main problem - which is the opposite as what the app developer promises - : it drains your battery. If you are near the laptop it keeps a permanent BT connection which drains your battery faster than what they say... The geofencing would be it will try to connect if you are at home only. But if you spend most of your time in the fence it will drain quite fast. Over 1/2 day it drained 20% more than usual. Its a gadget nothing more. 4 usd wasted which with a trial version I would never have wasted.
