Swimmer's High

Swimmer's High turns the swims your Apple Watch records into the analysis a coach would give you — instantly, beautifully, and entirely on your iPhone. YOUR SWIM LOG Every pool and open-water swim from Apple Health, grouped by week, each with its own barcode "fingerprint" of the workout. Your latest swim leads with its verdict, pace and SWOLF. THE POOL MATRIX • A true-to-scale 25 m / 50 m pool blueprint with lane ropes, flags and turn walls — and a replay of any length, one dot per stroke. • The lane barcode: every length as a bar. Height is speed, colour is efficiency, from peak-flow cyan to fatigue orange. Tap or scrub to inspect: LAP #14 · 25M FREE · 18.4s · 11 STROKES · SWOLF 29. • Rest intervals at the wall, shown or hidden with one tap. OPEN WATER • Your GPS route on Apple Maps, coloured by pace split by split. • Cadence stability, sighting drift and water temperature. THE SWIMMER'S HIGH COACH A verdict for every swim — sports-science accurate, with a sense of humour. Negative split with stroke counts locked in? Swimmer's High: unlocked. Technique falling apart at 1,200 m? It will find the exact metre — and notice the minutes you spent chatting at the wall. DEEP HYDRO-ANALYTICS • Stroke Efficiency Curve: pace against distance-per-stroke across the whole workout, with the fatigue decay point pinned. • Smart Set Grouping: warmup, main sets with send-off intervals, IM sets and total rest wall time — detected automatically. SHARE STUDIO Render crisp 9:16 Story and 4:5 post cards — a transparent telemetry sticker, generative swim-barcode art, or the coach's roast — and share them anywhere. PRIVATE BY DESIGN No account. No analytics. No ads. No servers. Swimmer's High reads your swims from Apple Health (read-only) and analyses them on your device. Nothing is ever uploaded. No Apple Watch yet? Explore three built-in sample swims: a negative-split pool session, a stroke-decay set in a 50 m pool, and a 3.2 km open-water swim on the Bosphorus. Swimmer's High works with swims recorded by Apple Watch in Apple Health. It is a training tool, not a medical device.
