I want to start measuring cadence; don’t care about anything else. I want to spend the least amount possible without sacrificing reasonable quality, so I thought to use my phone as the computer. The problem is I am a bit of a Luddite and do not understand anything about apps. My phone is a Samsung Model # SM-G550T1 Android Version 6.0.1.

If I turn on Bluetooth can I just get a sensor, such as the Wahoo offering, and go or is something else required?

Is using the phone as the computer a good idea?
