Phone mount/clamp/tripod for taking pics in the field?

As mentioned in another thread recently, my kids are at an age now where they are frequently hunting with me.

I like to document our time together and I'm looking for a mount to hold my phone and take pictures and videos during and after hunts.

I've looked at tripods with clamps, and somebody recently sent me a link to this mount. Looks a little sketchy to me.

Anybody here using anything similar or better?
