Nost or Die. Pit random images pulled from nostr against each other and vote. Adding Zaps soon (tm) https://nostr-or-die.replit.app/

forerunner 935 watch but i recently upgraded to an edge 840 on my road bike

Garmin thought my vo2 was 53 at the time I did the real test so it was a pretty good estimate. Garmin has a lot of workout data from me though that has heart rate and power so that must help accuracy

55 with a real test in 2021, garmin says 62 now

Nostr Or Die now at https://nostrordie.com ! - proper domain - implemented zaps via SDK so that my lightning node sends a 21 sat zap to the winner of each battle - sort by "most zapped" to get more popular content or roll the dice with "random mode" to get battles with random images
