I used my Mac the first time with the Tacx Flow to see differences between the different software versions.
iPad does record cadence, Mac doesn‘t. Anyone seeing this behavior?
then I wondered how can the tablet record cadence without the sensor?
So better to use a cadence sensor then?
Yes, it will make the measurements more accurate.
Is the Tacx app able to connect to that via Bluetooth?
Sorry, I can't give you a straight answer here. I use TTS4, and in the current TDA and TTA, something constantly breaks with each new update (as users report).
