Training for a marathon, a half, a 10K, a triathlon or an Ironman, with an Apple Watch on your wrist? Corpus is the running coach that writes your whole plan to race day and changes it as you train, day by day.
Your plan is 100% yours. Not a template with your name on it: it is built on what your body can actually do and on how you live, and it is made to bring out your best version.
Tell it your race and the days you can train. It asks what it needs to know, then writes every session from this week to race day: warm-up, work, cool-down and the pace for each.
Then it keeps coaching. Corpus reads your Apple Watch through Apple Health: sleep, heart rate variability, resting heart rate, every workout with its pace and route. When a night goes badly or a run comes in harder than planned, the coach sees it, and when you ask to move Thursday's intervals to Friday, the week changes on the spot.
WHAT YOU GET
• A full plan to race day, written in one conversation. Running, cycling, swimming and triathlon, from a first 5K to an Ironman.
• A coach you can talk to. Say a session felt too hard, report how a test went, tell it your week just changed. It answers from your numbers and adjusts your plan through the same conversation.
• Today's session on your Apple Watch. It waits under Up Next in the Workout app with every warm-up, interval and cool-down timed, and it follows every change to your plan.
• Your recordings, matched to your plan. Runs from your watch land at the top of the Plan tab, linked to the session they completed, with the hard efforts checked against heart rate and pace.
• Your habits, logged in a tap. A late dinner, a stressful week, a beer with friends: tap it, and Corpus learns how your life moves your training. Every habit has its own screen with ninety days of history.
• Insights from your own data. Corpus correlates what you logged with what your watch measured and shows you what actually moves your recovery.
• 3D route replays. Watch each run fly over the map in three dimensions, export the video, or share the workout as a link.

WHAT CORPUS NEEDS FROM YOU
• Record every session from the Workout app on your Apple Watch. Corpus reads it back with pace, heart rate and route.
• Wear the Watch to bed. That is where sleep, HRV and resting heart rate come from, every morning.
• Log your day in a tap. A late dinner, a stressful week: the coach learns how your habits move your training.
HOW IT WORKS
1. Choose your sport, your event and your date. Add a target time if you have one.
2. Connect Apple Health. Corpus reads only. It never writes to your health data.
3. Meet your coach. It asks about your training days and history, then writes the whole plan.
4. Train. Start today's session from Up Next on your Apple Watch, wear the Watch to bed and log your day. Open the app in the morning for today's session, and after to see how it went.
PRIVACY
Your health data stays on your phone. The coach sees only what it needs to answer: your message, a summary of your plan and the numbers relevant to the question. Nothing you say is kept on our servers beyond your plan while it is being written, deleted the moment your phone receives it. No ads, no tracking.
Corpus requires an iPhone running iOS 26 and works best with an Apple Watch. Corpus is a training tool, not a medical device; talk to a professional about any health concern.
