Hi, Am planning on trying out a trial on G6. Please forgive my potentially silly questions Can you start a G6 from any Android phone using just xDrip+ and no other device? Can you just not bother then with having to use the DexCom app at all? Do you need to do anything other than go into settings in xDrip & pair with G6 & then just let your sensor & transmitter continue on their own until they run out? Do you get more life out of sensors and transmitters with xDrip generally? Warm thanks
