Are you on winter or regular tyres? Either way it sounds less than ideal conditions. Cold weather a dash too much mechanical sympathy and 80kg (an adult male) extra weight. The weight wouldn't affect it massively. i'd say the cold and inaccuracy of the app are probably the biggest issues here.
Be interesting to see how mine fares when i get this OBD2 dongle.
