Live Leaderboard

Watch rankings shift in real-time as your crew sends. Every boulder logged updates the leaderboard instantly. The pressure is real.

Fair Competition

V3 vs V8? Fair game. Our skill-based handicap system gives weaker climbers score multipliers so everyone has a real shot at winning.

Jump In Anytime

Running late? Join a session already in progress. The handicap system adjusts so you're not penalized for a late start.

Timed Sessions

Set a countdown and race the clock together. When time runs out, final scores lock in. Who climbed the hardest?

Every send tracked.
Every session scored.

Log boulders as you climb. Grade, attempts, send or no send. CompSesh handles the scoring so you can focus on pulling plastic.

  • Flash bonus — first-attempt sends earn 20% extra points
  • Multiple scoring modes — Top 5, Top 10, Top 15, or All boulders
  • Timed or casual — set a countdown or climb at your own pace
  • V-Scale, Font, or custom — your gym, your grading system
Solo Session
No signal? No problem. Log every boulder offline. CompSesh syncs automatically when you get signal back. Built for gyms with terrible reception.
