Meryus Features
Meryus is a free fitness challenge app built for small groups of friends who want something more fun, flexible, and inclusive than the challenge features buried inside Strava or Garmin. Here's everything it does.
Built Around the Challenge
Strava and Garmin bolt challenges onto a much bigger app. Meryus is the opposite: the whole product is the challenge. Clean UI, clear chart, fast to set up, fun to check on.
Any Metric You Want
Miles, kilometers, steps, sleep hours, HRV, resting heart rate, weight, reps, workouts, sober days, push-ups, anything custom. Not limited to distance like the native options.
Anyone Can Join
Strava users join. Garmin users join. Friends with no wearable at all join and log by hand. Nobody is locked out because they're on the wrong ecosystem.
Real-Time Charts That Are Actually Fun To Watch
Every challenge has a live, color-coded chart showing each member's pace and trajectory. Updates the moment anyone logs or syncs.
Multi-User By Default
Share an 8-character join code. Friends sign up with email or Google and join instantly. No app install, no friend requests, no follower graph.
Open-Ended or Goal-Based
Set a finish line (200 miles in 60 days) or run forever (7+ hours of sleep every night). Same flow either way.
Strava Auto-Sync (Optional)
Connect Strava once and activities flow in via webhook within seconds. Optional; challenges work great without it.
Garmin Auto-Sync (Optional)
Connect Garmin Connect for activities, steps, sleep, HRV, and stress. Optional; challenges work great without it.
Cross-Service Deduplication
If you have both Strava and Garmin connected, the same workout is counted once. Matched by timestamp and distance.
Manual Logging
No wearable? No problem. Log any value by hand in seconds. Mix and match: auto-sync runs, manually log steps.
Email Milestone Notifications
Optional emails at 25%, 50%, 75%, and 100% of a goal, plus weekly AI summaries of the challenge.
Public Sharing
Optionally publish a read-only view of any challenge at a public URL. Great for sharing progress.
Data Export
Download every challenge's full activity log as CSV at any time. Your data is yours.
Privacy by Default
Challenges are private to people with the join code. No public feed, no algorithm, no ads. Row-level security on every database table.
