Got a training plan from an AI chat or your coach in a spreadsheet? Stop retyping it. Paste it into Stopa, see your full calendar, and sync each workout to your Apple Watch in seconds, or to Garmin, COROS and Suunto through intervals.icu. No plan yet? Build one with the in-app coach - a conversation, not a template library. With your permission it reads your Apple Health history, so the plan starts from the training you have actually done. You review and edit every workout before anything reaches your watch. Built for self-coached runners, cyclists, and triathletes who want their plan on their wrist - not stuck in a PDF. WHAT IT DOES ⢠Paste your plan from any AI chat or upload an Excel ⢠Or create one with the in-app coach, grounded in your Apple Health data ⢠See your full weekly and monthly training calendar ⢠Workouts reach your Apple Watch on their own, via WorkoutKit ⢠Garmin, COROS, Suunto and Wahoo through a connected intervals.icu account ⢠Auto-pairs completed activities back to the plan via HealthKit ⢠Compliance score after every session YOUR TRAINING DIARY Your whole history, not just the plan. Stopa reads your past sessions from Apple Health, so the diary is filled in from day one. Open any session for the full record: route map, splits, heart-rate zones, power - whatever your watch actually recorded. Add a note, or log a session by hand. STORIES Keep a stretch of training together - a weekend in the mountains, a training camp, a whole finished block - with its sessions, your notes and your photos. Share it as a card or a short film. FUELLING AND GUT TRAINING For long sessions and race day: carbohydrate, fluid and sodium per hour, built as a ladder that climbs across the block. Rehearse it in your long runs, tell Stopa how your stomach handled it, and the plan adjusts. Training intake only - no meal plans, no calorie counting, and nothing about body weight. GARMIN, SUUNTO, COROS AND MORE Your plan does not stop at the Apple Watch. Connect an intervals.icu account and it carries on to Garmin, Suunto, COROS, Wahoo and Zwift. Apple Watch stays the direct route. SEVEN LANGUAGES English, Czech, Spanish, German, French, Italian and Brazilian Portuguese - the app, the watch and the widgets. The plan reader speaks them too, so a Czech coach's spreadsheet is read in Czech, not translated first. WHY STOPA Most training apps lock you into an algorithm you cannot see, or charge $99+/year for what amounts to a calendar and watch sync. Stopa takes YOUR plan, in YOUR format, and gets it onto YOUR watch. And when you do want help writing one, the coach shows its work - every workout is yours to edit. SPORTS SUPPORTED Running, cycling, triathlon, swim. WATCH SUPPORT Native Apple Watch via WorkoutKit. Apple Watch Series 8 or later recommended. watchOS 10+ required. Garmin, COROS, Suunto, Wahoo and Zwift through a connected intervals.icu account. PRICING See week 1 of your own plan, in your paces, before you pay. Stopa Pro, monthly or yearly (founder price): watch sync, unlimited plans, coach chat, AI parser fallback, full training history, stories, fuelling plans, widget. The yearly plan starts with a 7-day free trial for new subscribers. The monthly plan starts the day you subscribe. Subscriptions renew automatically until you cancel in Settings. Made for athletes who think for themselves. stopa.app Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
SwimTune

SwimTune turns your swims into a training plan that changes with you. Most swim apps count laps. SwimTune reads what happened in them ā 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 ā 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 ā 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.
