About ATHRON
The next best decision. Always. Your coach decides with you every day: what is right today, and why. ATHRON is your decision coach for triathlon, running and cycling. Instead of just displaying plans, ATHRON decides with you every day: What is the right session today? Why? And what changes when recovery, sleep or life demand it? An adaptive plan, not a rigid cycle Your training plan is not a document. It is an ongoing decision. ATHRON adapts day by day based on HRV, body battery, sleep, life stress and your race goals. TODAY: one decision, three modes - Quick: What now? One sentence, one action. - Coach: Decision + reasoning + next step. - Analysis: Context, data, trade-offs. Nutrition that matches the training Calorie and macro targets that move with your training week — hard days differ from rest days. Log meals by photo or barcode. Recipes that respect your taste, your diet and your allergies. Understand your blood work (Premium) Upload your lab report and see what it means for your training: trends over time, the link to load and recovery, concrete conclusions for nutrition and regeneration. Not a diagnosis — context. Integrations, never mandatory ATHRON works completely without any integration. Garmin, TrainingPeaks, Intervals.icu, Oura, WHOOP and Withings are additive data layers, not requirements. You decide which source leads. Data sovereignty Your health data stays in the EU (Hetzner Frankfurt). No sharing with training-data brokers. No ad tracking. Honest empty states No fake coaching, no invented numbers. When data is missing, ATHRON says so — and tells you the next step. Who it is for Triathletes, runners and cyclists who want to plan like a coach, not like a calendar. Intermediate to advanced. Subscription After registration, Pro and Nutrition are free for 30 days — no payment details, no automatic renewal. After that: - ATHRON Pro: €5.99/month or €59.99/year (two months free) - ATHRON Nutrition: €5.99/month or €59.99/year (two months free) - ATHRON Premium: €12.99/month or €139.99/year — includes Pro, Nutrition and blood-work analysis Subscriptions renew automatically until you cancel.

What’s new
Version 1.3.1 · Updated October 20, 2026
New in 1.3.1 • Share a workout as a short video: a Reel with a 3D fly-over of your route. • A short tour explains HEALTH and FORM the first time you open them. • TODAY has a new photo and greeting, and the app starts much faster. • Apple Health: clearer messages, and "Sync now" syncs right away. Races • The race detail screen is new: a card with the essentials on top, plus start time, forecast next to your goal, your race window and the split times for your goal. • If you have several races, Athron checks that they fit together. Coach • You can now change your season build in the chat. Just tell Athron where the focus should be. • Voice input no longer cuts off when you pause, and no longer hangs when nothing was recognised. • Your daily verdict now comes from your recovery alone. Week • "Build week" shows a draft first. It only goes into your calendar when you tap "Looks good". • If a session is cancelled, it now shows struck through with the reason in the day list. • If you change the sport of a session, its title, analysis and load follow. Privacy • New consent texts and an updated privacy policy. The privacy switches are combined under "My AI Coach", and Athron asks you once about AI coach and group comparison there. • The start and end of your GPS routes are stored trimmed (about 200 m), so your home can't be read from the route. Also • Feedback sent without a connection goes out automatically later. • The night report only gives a verdict once there is enough to compare against. • Your weight shows up-to-date in settings right away. • Many small fixes.
