Our story
Born on the court.
Rebel Lion Labs started out of frustration. We've played sport all our lives and tried just about every app, tracker and platform going, and none of them got it right. They never matched how much players care about their game.
Padel made the problem impossible to ignore. You finish a match, the score is on the whiteboard, and there's nowhere useful to put it: no rating to update, no leaderboard to climb, no way to find better opponents for next week. You book the court in one app, sort out the game on WhatsApp and keep the rankings in a spreadsheet. Then the result is gone.
We decided to build our own apps, for players and by people who play. Each app focuses on one sport and gets the details of that sport right.
“We were staring at a score that was about to be wiped off the whiteboard, thinking: why doesn't this exist?”
Why padel first

- Courts worldwide, with more opening every week
- 50,000+
Padel is growing fast all over the world, but the apps players use haven't kept up. Most people still track results in group chats, argue about who's a 3.5 and who's a 4.0, and struggle to find opponents at their level.
PADLR. is the app we needed every time we walked off court with a result and nowhere to put it. That made padel the obvious place to start.
How we build
The four principles we build by.
We wrote these down early on. They've guided every product decision since.
01
Transparency
You should always know why your rating moved. PADLR. explains every change in plain language, so a drop makes sense and a rise shows what earned it.
02
Fairness
Every competitive result goes to your opponents to confirm, so nobody can just claim a win. The maths allows for partner strength, and automatic checks look for anyone trying to game the system.
03
Community
Padel is social, and PADLR. is too. You can follow friends' matches, earn badges for milestones and find new players at your level.
04
Simplicity
Logging a match should take 30 seconds: add the players, enter the score, done. If logging feels like a chore, people stop doing it.
Our first app · Padel
PADLR. is an app for padel players. It gives you a skill rating on a 0–7 scale that updates after every confirmed competitive match and shows you why it moved. You can also log matches, find players near you, join open games and climb the leaderboards. The rating runs on OpenSkill, a Bayesian system built for team sports.

Our vision
One sport at a time.
PADLR. is our first app, and there will be more. We give each sport its own app instead of squeezing every sport into one.
After padel we'll take on other sports, one at a time. We also plan to make merch and apparel for the community.
