CMF1_hacker It definitely connects to Strava via the Nothing X app. Very easy to set up. For me, works every time with every activity. I have synced hikes, and walks and cycling data. GPS is very close to what my Garmin Edge measures in miles on my bike, within a few 10ths over 50 miles of cycling. But when you get to an intersection or make sharp turns on the bike, the data definitely looks like a strait line and not a curve, but again, no big deal. When going slower while walking or running, the curves show up. But as of 8/31, the HR data does not sync to Strava. Let’s see if today’s firmware update or the next Nothing X app update fixes that. HR data is pretty comparable to my Garmin HR chest strap. Only thing I noticed is that over 3 hours with 50 miles of cycling and continuous HR monitoring the battery drained 20% or so.
