Each app differs a bit in auto-pause/resume timing, which can lead to some differences in longer rides with lots of stops. But overall they're pretty similar.

Most will disregard rest breaks, while continuing to log total activity time. Some will resume recording if you walk with the bike, or carry the phone on your body while walking. So with some apps you may want to manually stop the app while on long rest breaks or walking around, then remember to resume later. It should pick up where you left off.

Cyclemeter's auto-pause/resume seems to favor faster actual moving times and records me as consistently faster. The auto-pause/resume isn't user adjustable, although it can be disabled. It seems to kick in almost immediate upon stopping or slowing below a certain speed, then resumes only after I'm back up to speed. So it usually records me as 0.5 mph faster than Strava on most rides.

Strava (free version), Wahoo Fitness (completely free) and a couple others I've tried offer auto-pause/resume as a standard feature. I've run them simultaneously while riding my bike or as a passenger in a vehicle, and they all differ slightly in auto-pause/resume timing. At least one of those apps had user adjustable auto-pause/resume, but I don't recall which.

I'm pretty sure Ride With GPS and Map My Ride have this feature as well, although I haven't tried those since last year.
