Why CourtSauce exists

The frustration that became CourtSauce started on a pickleball court in Oakville, Ontario. It was a Tuesday evening league night — the kind where four adults who’ve been meaning to get back into a sport finally do — and nobody could remember the score.

It’s a universal experience for pickleball players. Pickleball’s serve rotation is famously confusing. Two servers per side in doubles, sides switch at 11 in rally scoring, server numbers reset, which side are we on now? Everyone has had the conversation. A lot of players have started using apps.

The apps were mostly terrible.

Not technically terrible — some of them were polished, well-designed pieces of software. Terrible in the sense that they solved the wrong problems. Most scoring apps were built as add-ons to social ladder systems, ranking platforms, or general fitness trackers. Scoring was never the main event; it was the feature you needed to unlock the social graph, the ratings, the ads. To record a point, you stopped play, dug your phone out of your pocket, opened the app, found the right button, tapped it. By the time you finished, the next point was already underway.

There’s an Apple Watch on my wrist. It’s literally designed for this exact problem.

The watch-first idea

Apple Watch was designed for moments when you need to glance, not stop. It’s there when your hands are occupied, when you’re moving, when looking at a phone would break your concentration. For scoring a racquet sport, that’s exactly the context. You want to record the point without leaving the point.

The design idea was simple: tap your side or theirs to add a point. A turn of the Digital Crown undoes a mistake. Glance to see the score, who’s serving, which server number. That’s the entire input model — no gestures to learn, no menus to navigate. The watch handles the scoring; the phone handles the context.

When I built the first version, the experience was immediately different. You finish a point, tap your wrist, and you’re back in the rally. No fumbling for a phone. No breaking eye contact with the court. The score is just there.

That single design choice — watch as primary scoring surface, phone as supporting context — shapes everything about how CourtSauce works. Feature decisions get evaluated against it: does this make the watch experience better? Worse? Does it belong on the phone instead? The answer usually makes it obvious where something should live.

The voice notes experiment

One feature I didn’t expect to use became one I can’t play without: voice notes.

During a match, you notice things. Your opponent has a weak backhand on the run. You’re winning the third shot drop but only when you’re moving forward. Your partner’s dink is drifting right when they’re tired. These observations evaporate the moment the match ends because you’re immediately into the next one, or dinner, or the drive home.

Tap and hold the watch face to record. Say the thing. Keep playing.

In version 2, transcription happens on-device using Apple’s speech recognition. You can read the note later without listening. And because the transcription happens on your iPhone, nothing ever leaves your devices. Your match observations stay private.

The voice notes feature is genuinely useful for players who want to improve. It’s also the feature that most surprised testers: “I never knew I wanted this until I had it.” That reaction is the goal.

Why privacy matters here

The racquet sports app space has a data collection problem that nobody talks about much.

Ladder systems and social platforms need data to function. They need to know who you played, when you played, what your ratings are, who you’re connected to. That’s defensible — that’s the product. But the side effects compound: your match history gets mined for patterns, your fitness data gets aggregated with other users, your behaviour in-app feeds advertising systems or gets sold to third parties.

I wanted to build something different. Not as a political statement, but because I’ve spent time thinking about what kind of software I want to put into the world.

CourtSauce’s architecture is designed so we don’t have access to data we don’t need. Match data lives on your devices, synced through your personal iCloud account. We don’t have servers holding your match history. We don’t require accounts. HealthKit data stays in HealthKit — we read it during matches, but we don’t copy it somewhere else. Voice notes are transcribed on-device using Apple’s framework; the audio never leaves your phone.

This isn’t technically difficult. It requires making privacy a constraint from the beginning rather than retrofitting it onto a data-hungry system later. We made it a constraint.

The result is an app that works better for users who value privacy, costs nothing extra for users who don’t think about it, and sleeps better at night.

What sports deserve this

Pickleball came first for practical reasons. It has the fastest-growing player base of any racquet sport in North America. Its scoring rules are genuinely complex enough that an app helps. Its players span a wide range of technical sophistication — serious competitors down to people picking up a paddle for the first time — which forces good UX. And it had the worst existing apps, which made the opportunity obvious.

But the design works for any racquet sport with a scoring system that benefits from point-by-point tracking. CourtSauce Tennis brings set, game, and tiebreak scoring to the same watch-first design. CourtSauce Squash handles PAR scoring and traditional formats, including hand-out tracking for when that matters.

We’re working with Melanie Jans on the squash design — she’s a former world number 25 and Pan American medalist, and her input on sport-specific rules (particularly around let decisions and traditional scoring edge cases) has been invaluable.

Each sport gets its own dedicated app rather than one multi-sport app that handles all of them. This is deliberate. Pickleball players shouldn’t navigate through tennis and squash options to get to their game. The watch face for each sport should feel tailored to that sport’s specific scoring logic. The apps share design language and core architecture, but they’re built for the sport they serve.

The platform layer

Above the individual sport apps is a layer most players won’t think about until they need it: tournaments and leagues.

Running a tournament with paper brackets and a spreadsheet is a manual process that breaks at exactly the wrong moments — when you’re managing 40 players at 10 courts and someone wants to know the results from court 7. CourtSauce Tournaments will be a web-based platform for running racquet sports tournaments, accessible from any device, integrated with the scoring apps your players already use.

CourtSauce Leagues manages seasonal club play — standings, schedules, match results, captain coordination, and convenor tools. If you run a recreational tennis league at a club where half the players have iPhones and half have Androids and some don’t have smartphones at all, CourtSauce Leagues works for all of them without requiring anyone to install anything.

Both platforms come after the sport apps are stable. The sport apps are the foundation. The platform is what you build when the foundation is solid.

What “extra sauce” means

The brand name, since a few people have asked: “sauce” is slang for skill, flair, or style. The kind of thing that makes good players recognizable — not just technical competence, but something harder to define. They’ve got sauce.

Court + sauce. Your game, with extra sauce. It’s both a statement about what we’re building (tools that make your game better) and a claim about where we’re coming from (people who love these sports enough to care about the flair in them).

The name is playful. The software is serious. That tension is intentional.

Where this goes

CourtSauce Pickleball is live on the App Store. CourtSauce Squash and Tennis launch later in 2026. Tournaments and Leagues come after that.

Beyond that: more sports are obvious candidates — badminton, racquetball, padel. More analytical depth. Better integration with existing ranking systems like DUPR for pickleball and UTR for tennis. Possibly features for coaches, clubs, and tournament directors we haven’t imagined yet.

But the foundation stays the same: watch-first scoring, sport-specific design, privacy by default, careful craft. Every version of every app gets a little better. That compounds.

If you play racquet sports and you’ve been frustrated by the tools available, CourtSauce is for you. If you run tournaments or leagues and you’re tired of the spreadsheet, get in touch. And if you just want a pickleball score app that actually works, it’s in the App Store.
