How it works
How Open Tennis League works
From an account to your first confirmed result in four steps - and what happens in the app along the way.
How it works
From sign-up to your first match in four steps
No club membership required, no fee to open an account. A league fee, when there is one, is set by its organiser.
Create an accountStep 1: Create an account
E-mail, a short level questionnaire and you are in. Free for players; no club membership required.
Step 2: Find or start a league
Browse leagues in your town and sign up – or set up your own, public or private, in a few minutes.
Step 3: Mark when you play
Tick your free hours. The app pairs you with an opponent from your division and proposes a time and a court.
Step 4: Play and enter the score
After the match one of you enters the result, the other confirms it. The table and your rating update on the spot.
What is in the app
Everything a league needs, in one place
Every feature below exists because somebody used to do it by hand - in a spreadsheet, a group chat or at the club reception.
The table updates itself
One player enters the score, the other confirms it. Points, positions, promotions and relegations follow at once – nobody keeps a spreadsheet, nobody chases anyone.
Fixtures from your calendar
Mark the hours you can play. The app finds an opponent from your division with a matching slot and proposes a time – instead of a chain of “so when?” messages.
OTL rating and levels
A short self-assessment sets your starting level; confirmed results move it from there. Divisions are drawn from the rating, so you meet opponents who make you work.
Challenges and friendly matches
Between league rounds, challenge anyone at your level in the community. Friendly results count towards your rating, so the off-season is never dead time.
Court booking in the same app
The club schedule online: free hours, the price list and a booking in three taps. Match proposed, court booked, done – no phone call to reception.
The table on your club website
Every league ships with an embed snippet. Paste it into any page and the live table, fixtures and results appear there, updated automatically.
Reply from your inbox
Requests for a date, a challenge or a result confirmation arrive by e-mail with a one-tap answer. You confirm without logging in; scores themselves go in through the app.
Private or public leagues
A private league joins by link only – perfect for a club ladder. A public one is listed for the whole town after a quick moderation. Switch at any time.
Club directory by region
Clubs listed by voivodeship with surfaces, hours and prices. Claim an existing listing or add a new one; a moderator checks it and the club goes live.
Entry fees and settlements
Set an entry fee, see who has paid, export the season’s settlement. Venues get the same for bookings, monthly and per court.
Pick your surface
Every court has its own colour
Switch the look of this site to the surface you play on. The choice stays in your browser - the ball stays green on all three.
FAQ
Questions before the first serve
Does it cost anything to join?
Creating an account and playing friendly matches is free. Some leagues charge an entry fee set by their organiser – you see it before you sign up.
How does the app know my level?
At the start you answer five quick questions (how long you have played, how often, serve, rallies, matches) and get a suggested level on the 1.5–5.5+ scale. You can correct it. From the first confirmed result the OTL rating takes over.
I am not a member of any club. Can I still play?
Yes. Leagues are open to anyone at the right level. You need a court for the match – booked through the app at a listed club, or anywhere you and your opponent agree.
What if my opponent enters a wrong score?
Nothing changes until you confirm. Reject the result and the organiser gets a dispute to settle. Until then the table stays as it was.
How much time does a season take?
A typical division has 6–8 players and one match per round; rounds are usually two weeks long. Count on one match every two weeks, at a time you chose yourself.
How long does it take to set up a league?
Ten minutes: name, town, format (groups, points, promotion rules), visibility and an optional fee. Players sign up by themselves; the draw happens when you close entries.
