Bluetooth and compatible with Android for an analogue trainer
Cheap is good 😀
Wahoo?
Just pony up for the Wahoo sensors! They've both been flawless for me, the cadence can sit on your crank or on the shoe which is handy if you have multiple bikes.
The speed sensor just wraps around the rear hub with an elastic band.
I had Garmin equivalents but they were glitchy and unreliable.
I use this one most days on the turbo for a cadence sensor and also sometimes use it on the MTB as a speed sensor connected to my garmin. No issues and nice and cheap!

I’ve got that CooSpo one on my turbo (and therefore sadly, most used) bike. Been faultless over the last year or so

We've got 3 of the CooSpo things, although they are branded slightly differently.
Work well enough but don't like cheap batteries (eat them quickly).
Used Duracell last time and so far seem to be lasting well.
