Level-Matching Algorithms: How NTRP, DUPR and UTR Work
How does level matching work in racket sports apps? We explain the NTRP, DUPR and UTR scales, the logic behind Elo and Glicko, and how to find a balanced opponent.
Do tennis and padel partner apps really need a paid membership? What paid plans promise, locked inboxes, level systems, fake profiles and what to check before you pay.

After music, TV and cloud storage, sports apps have moved to monthly subscriptions too, and many people are tired of paying a separate monthly fee for every need. Partner-finding apps for racket sports run different business models: some sell a monthly or yearly premium membership, some take a service fee on court bookings, and some are free for players. Paid plans usually promise extras such as unlimited messages, more match requests, advanced filters, no ads or a boosted profile. Whether paying is worth it depends on what those features would change in your case.
No. A partner-finding app is worth as much as the number of people who play in your area at your hours, and premium does not add to that number. When basic communication costs money it can even work the other way: beginners and people who only want to try the app leave without paying, and fewer people are left to answer you. Use the free version first and look at the activity around you: how many people near you have picked your sport and level, and how quickly do they reply to invitations? If the answers are weak, a paid plan will not change the result.
The most common scenario in some apps goes like this: you see a player near you at your level, you want to invite them to a match, but sending a message requires an upgrade. On top of that you often cannot tell whether the profile is still active. Before you pay, check: does the free version limit messages or requests, can you see when the other player was last active, does the subscription renew automatically after the trial, and is it easy to cancel? Subscriptions bought through a store are cancelled from the subscriptions section of your App Store or Google Play account; deleting the app does not end them.
Tennis and padel take a budget: court hire, rackets, strings and balls are already regular costs. Paying a separate monthly fee on top just to talk to someone to play with makes the sport harder to keep up. If your budget is tight, it makes sense to put the court and equipment first and try the free options for finding a partner before paying.
| Topic | Common in paid plans | Racket Crush today |
|---|---|---|
| Messaging | A membership or credits may be needed to message or start a chat | Free; no message limit with your matches or in match chats |
| Discovery and match requests | There may be a weekly swipe or request limit | Free, no swipe limit |
| Publishing a match | The number of posts or boosting a post may cost money | Free; open a singles or doubles match |
| Level | Some apps use a rating updated by match results | Self-declared and not changed by matches; scores are confirmed by both sides |
| Payment | Auto-renewing monthly or yearly subscription | No in-app purchases, no card details asked |
Apps that require phone verification at sign-up make fake accounts harder to create. Being able to block and report a disruptive user is another basic safety measure. On Racket Crush sign-up uses SMS phone verification; you can block a user or report them from their profile, and the Racket Crush team reviews reports. Arranging your first match at a busy venue is a sensible precaution in any app.
WhatsApp groups work quickly within a circle you know, but their limits are clear: messages get lost as the group grows, there is no level or location filter, and if you have just moved to a new city there is no group to join. Apps put you in touch with players who have never met you but want to play at the same time, nearby and at a similar level. The two are not alternatives; many players use both.
Today every Racket Crush feature is free: building a profile, discovering players near you, matching, messaging, publishing a match and recording the score cost nothing, and there are no in-app purchases. The reason is simple: a partner app is worth as much as the number of players using it. A good match for you depends on enough people playing near you at your hours, so in this first stage our priority is growing the community. The app covers tennis, padel, squash, badminton and pickleball and is available on iOS (Turkish App Store) and Android. If you want lessons, the coach sets the price and payment currently happens outside the app.
Communication: do you have to pay to talk to someone you matched with, and does the free version limit messages or requests? Community: when you open the app, can you see active players near you who play your sport? Level: how is level set; is it only self-declared, is it updated by matches, can it be compared with a known scale such as NTRP? Safety: are there phone verification, blocking and reporting? Ease: can you publish a match and apply to existing ones in a few steps? Put your money into court time and equipment first, and try the free options before paying to find a partner.
