Strava records the activity once it's done: time, distance, segments, and the feed where everyone gives kudos. A Strava club is that shared feed, a leaderboard between members and events people can say "I'm going" to. It does this very well, and Buddiz doesn't redo it.
What it lacks is the social piece before: finding who to run with when you don't have a group yet, setting a meet-up, knowing who's coming. Buddiz is that piece. It measures nothing, shows no times and leaves performance to Strava.
With Buddiz: the link to your Strava club appears on your page, a route exported as GPX can be imported on a session, and a session's route exports as GPX for your watch.
Everyone has it, and many groups live there: the jokes, the photos, the "who's up for tomorrow?". Buddiz doesn't ask anyone to leave it.
It's also where the time and place get lost among three hundred messages, where thumbs-up get recounted, where someone has to chase every week, and where a newcomer only gets in if they already know someone.
With Buddiz: each session has its page, its list of who's in and its reminder, and your WhatsApp group stays linked on your page.
A Facebook group can be found from Google and welcomes everyone, and a Facebook event can tell who's interested. Many hiking and cycling clubs still announce themselves there.
But what members see depends on the algorithm, the "interested" don't always show up, and part of the athletes aren't there any more.
With Buddiz: a published session is seen by everyone nearby, with no algorithm, and attendance is counted.
Buddiz starts where the others stop: finding who to move with and setting a meet-up. A club gets a public page, sessions with spots, sign-ups and a reminder, one chat per club and per session, and attendance counted.
It measures nothing, shows no times and charges the club nothing for its sessions. Performance stays on Strava; connection and regularity happen on Buddiz.
