Smart Scale Sync is a services developed by Patrick Renschler from Renschler Labs LLC. I hope this Smar Scale Sync will help me to get the weight from the Renpho Smart Scale to Polar Flow (which I use in combination with the Polar Vantage M).
It is an online service that allows you to sync weight metrics from three supported sources Garmin, Fitbit and Withings to support destinations Garmin Connect, TrainerRoad, Strava, Concept2, Peloton, Zwift, MyFitnessPal, Fitbit, Polar Flow and Withings.
The Wahoo Tickr X is a heart rate sensor that was used by team Sky in the recent Tour de France 2016 stages (in the Pyrenees, the jerseys are wide open).
The Tickr X is Wahoo’s flagship heart rate monitor featuring dual band ANT+ and Bluetooth 4.0 wireless capabilities. The build-in memory can record up to 16 hours of training. The Wahoo Tickr X can be connected to almost every iPhone or Android smartphone, but also a wide range of tablets and ANT+ enabled devices like for example cycling computers.
Personally I use the Wahoo Tickr X in combination with my Pioneer Pedaling Monitor System (SGX-CA 500 computer and SGY-910HL power meter).
