Best aero bar mount for iPhone plus?

Got a cadence, mph sensor and heart rate monitor

I searched but didn’t find best way to mount iPhone plus to aero bars so I can use the app while riding
.

You probably have to botch something using a Quadlock case.

i would seriously recommend just getting a cheap cycle computer - especially if all you require is mph cadence and hr. iphone plus is a big weight - one big bump and you can kiss it goodbye
