About SwimTune

SwimTune exists because of a gap every serious swimmer eventually notices: the apps count your laps, and then they stop looking.

Last updated 12 August 2026

Where it started

SwimTune was founded by a lifelong swimmer. The relationship with the water started in childhood and never let go: years of training, local competitions, and amateur open water races. Not an Olympian, not a coach with a whistle, just someone who has spent a large part of their life staring at a black line and the rest of it thinking about how to swim it faster.

That kind of swimmer accumulates a very specific frustration. You finish a session, your watch dutifully reports laps, splits and a SWOLF score, and then... nothing. The numbers sit there. No app said what they meant, what to do on Thursday because of them, or whether the tiredness you felt was fitness being built or a warning sign.

The gap we built for

Every swim app we tried had the same blind spot: it treated swimming as the only thing happening in a swimmer's life. The swim got tracked; the swimmer didn't.

But the watch on your wrist, or the band you sleep with, already knows the rest of the story: how you slept, what your heart rate variability is doing, how your body is recovering, what other training you did this week. None of it reached the plan. An app would happily prescribe a threshold set the morning after your worst night of sleep in a month, because it had no idea the night had happened.

That is the gap SwimTune was founded to close. Not another lap counter, and not a workout library, but a coach that looks at the whole athlete: the swims, the health metrics from your devices, the training done outside the pool, and builds each session from all of it.

What we believe

A few principles run through every decision in the product:

• The plan should respond to the body. Sleep, HRV and resting heart rate shape a daily readiness score, and when readiness drops, the plan backs off. Adaptation happens during recovery; a plan that ignores recovery is just a fatigue schedule.
• Honest data beats flattering data. Open water pace is deliberately kept out of CSS calculations and personal records, because current and sighting make it incomparable to pool pace. We would rather tell you less and have it be true.
• No hardware tax. SwimTune works with the Apple Watch you already own. No proprietary goggles, no specific watch brand required, and swims recorded on other devices import through Apple Health.
• Tracking is free. Recording, importing, your full history, analytics, training load and recovery signals cost nothing. The AI coaching is what SwimTune Pro pays for.
• Explain, don't dictate. Every session comes with the why in plain language. A swimmer who understands the purpose of a set executes it better, and eventually needs the explanation less.

Where we are now

SwimTune is launching on the App Store for Apple Watch and iPhone, with native Garmin support planned for fall 2026 and Google Wear OS to follow. The guides we publish are free and always will be: if one of them answers your question and you never install the app, that is a perfectly good outcome.
