SwimTune

SwimTune turns your swims into a training plan that changes with you. Most swim apps count laps. SwimTune reads what happened in them β your pace, your stroke efficiency, how hard the session actually was and adjusts what comes next. BUILT AROUND YOUR RECOVERY Every morning SwimTune scores your readiness from your sleep, resting heart rate and heart rate variability, and says plainly what to do with it. Slept badly? Today's session gets easier on purpose. Loaded up too fast? You'll be told before your body tells you. A PLAN THAT ADAPTS Set a goal β a first 1 km, a faster 100, an open-water event and get a structured plan with a real progression through base, build and peak. Miss a session and the plan absorbs it instead of guilting you about it. ON YOUR WRIST The Apple Watch app tracks your swim live: split times, stroke count, heart rate, and your target pace right on the screen. Sets and rests are laid out so you know what's next without stopping to think. NO WATCH? NO PROBLEM Log a swim by hand in a few seconds. Distance, time, how it felt. Your plan, your progress and your training load all work from that alone the app never pretends to measure something you didn't record. SEE WHAT'S ACTUALLY CHANGING Swim Score tracks your progress across pace, efficiency, consistency and volume. SWOLF, CSS, personal records and training load are all there when you want detail β and honestly blank when there isn't enough data to say anything yet. DRYLAND THAT FITS SWIMMING Short shoulder-care and strength sessions built for swimmers, counted into your training load like any other work. FREE Manual logging, your full history, Swim Score, readiness scoring, training-load tracking and every safety warning are free, forever. We never put a paywall in front of a signal telling you to rest. SWIMTUNE PRO Unlocks the AI: personalised training plans, daily coaching, plan adjustments when life gets in the way, and a coach you can actually ask questions. $19.99/month or $109.99/year. Start with a 7-day free trial. Requires an Apple Watch for automatic swim tracking; everything else works from your iPhone alone. Health data stays on your device unless you ask us to sync it, and is never sold or used for advertising.
