Totally useless
I bought a sensor to use with the Fiit app. My experience so far: - has taken me about 30 mins each time to connect the sensor to my phone - the FAQs on the app takes you to non-existent pages so no help at all - when pairing it asks for the code shown in your sensor. There is no code - battery life is nowhere near what they claim Complete waste of money. I shall be returning mine for a refund
