One rival. Zero spectators.
Private 1v1 challenges and a real global Top-50 XP leaderboard. Scoring is privacy-preserving by design: your rival sees the score — never your data.
Pick a rival. Pick a metric.
A challenge is one person, one metric, one fixed window. You both start together, you both finish together, and the score settles the argument.
Workouts
Sessions completed inside the challenge window.
Minutes
Total training minutes logged, rep by rep.
Nutrition days
Days you logged your nutrition and kept the picture honest.
Check-ins
Days you showed up — the quietest metric, and the hardest one.
A fixed window, for both of you
No moving finish lines. The challenge runs its window and ends when it ends — for you and your rival alike.
The score travels. Your data never does.
Your rival sees a single number per metric — never your workouts, your food log or your check-ins. Compete on effort, not exposure.
Leaderboard · Top 50
Standings shown as bars — the live board is in the app.
Top 50, worldwide.
The leaderboard is real: a global Top 50 ranked by XP — the XP you earn one completed session at a time. Flip the friends filter to race the people you actually know.
Earned, never bought
XP comes from finished sessions and consistent weeks. There is exactly one way up this board: do the work.
Global or friends
See where the work puts you against the world — or narrow the board to your own circle with the friends filter.
Badges don't lie.
88 achievement badges run from Entry tier to Burnix Legend. Every one is earned in the log — sessions finished, streaks held, targets hit. That is the only social proof Burnix deals in.







No feed. No followers. Just the work.
Burnix community is competition, stripped to what matters: one rival when you want heat, one leaderboard when you want scale, and a badge case that only fills up one honest way.
