Pointless app- don't use it. Don't buy the device!
The One touch device takes it's measures in mg/dl (cannot be changed)but the app only accept readings in mmol/L. ONLY after you purchase this product and try to pair it with your phone do you find this out so you cannot use the app with the device. Complete waste of money as none of the additional functions can be used... And that's why you pay more for the unit. What a waste.
