01
Workouts built for you
Tell Delta your event, your level, how much time you have, and what you’re training for. It writes each workout specifically for you, then rewrites the next one as your season progresses.
02
Your lane coach
Take your phone or watch to practice and Delta walks you through every repeat: pace targets, rest timers, haptic cues, and optional voice prompts. You just swim instead of memorizing the set. Apple Watch, Garmin, Coros, and more sync automatically.
03
Every swim, remembered
Your workouts log themselves. Splits, distance, heart rate, and consistency all roll into one training history. Instead of dumping graphs, Delta tells you what the numbers mean: “you held pace through all eight repeats today; last month you faded after six.”
04
Coaching that remembers you
This is what makes Delta a coach, not a workout generator. It remembers your whole season: a rough set last Thursday, two bad nights of sleep, three weeks out from championships. Today’s practice gets shaped around all of it, right down to when to start your taper.
05
Know when you’re ready
Delta tracks your current time against your goal, the qualifying standards, and your meet schedule. Instead of a number on a wall, it tells you where you stand: “you’re 0.8 seconds away, and on recent training you’re likely ready within the next three meets.”
06
Technique analysis
Coming next The one we’re building toward. Upload a video of your stroke and Delta breaks it down frame by frame: catch, rotation, breakouts, turns, stroke rate, distance per stroke. Every note links to the exact frame, so instead of “your catch needs work” you get “your elbow drops here, frame 142, and here’s how to fix it.”
The Hajos suite One backbone.
Four products.
Delta builds on the times and history the rest of Hajós already captures. Your meets and results become the baseline for your training.
