I was curious what you all use and/or recommend as a mount to put your iPhone on the bars of your road bike?

I use my iphone's built in fitness tracker to track my rides. I wear an apple watch - and between the HR monitor and GPS in my phone - it seems to do a pretty good job of telling me mph, total distance, HR, etc.... right now I have to flip up my writst and look at my watch to get this data as I ride..and it's not idea to pull my hand of the bars...

i'd rather have my phone mounted to the stem or handlebars so I can just glance down and see the info as I ride.

I have seen several systems. one thatl ooked cool was called Studio Proper.. it is a magnetic system where you put their mount on yoru stem, use their iPhone case..and it just magnetized to the mount... although I saw a YouTube review that basically said it doesn't work and his phone fell off repeatedly... not sure if it was just a competitor posting to damage their reputation or a legit customer.. anyway.. curious if anyone here has tried it.

there is quadlock and rokform which look similar to the Proper mount - only they snap in with a twist mount.

is there any reason I am not aware of as to why a dedicated bike computer would be better than using my iPhone mounted to the bars? Is there something that I can measure with a bike computer I can't do with my iPhone? I am nsomewhat new to cycling... so far I only track my distance, speed, calories burned, HR, etc..

I know there are ways to measure cadence and watts...not sure if that is something most advanced riders are tracking real time as they ride and whether an iPhone can measure those too? do you need special meters on the bike frame/wheels to do those or can you just have the right app/software?

i'm not opposed to a dedicated bike computer..but the good ones look to be a few hundred bucks and if my ipone will do it all - why not just use that!

I would prefer a mount that is clean and sleek.. the mounts that attach tot he stem look nice..the quadlock seems a bit cheap looking as it mounts with rubber bands..but my bike light mounts that way and it works great..so maybe it's not so bad.

function is more important than form...but having it look sharp and sleek doesn't hurt either.

any photos, comments, or observations are appreciated!! thanks!
