Strathlon™
Your AI coach for training & nutrition
Strathlon builds a training and nutrition plan around you — your body, goals, sport and schedule — then coaches you through it day by day. On your iPhone.
A real coach in your pocket
One app instead of five — Strathlon brings your training plan, nutrition tracker and AI coach together, so you're not stitching a workout app to a calorie counter to a separate tracker. Everything below is built in. The AI Coach features (chat, meal plans, photo logging and your AI progress insights) are the premium tier; your plan, timers, targets and tracker come with the app.
Everything in one app
Your training plan, calorie & macro tracker, AI coach and progress charts in a single app — instead of juggling a workout app, a food logger and a separate tracker. One place, one plan, all working together.
AI Coach
Chat with a coach that actually knows you — your profile, goals, sports, training history and today's targets, not a generic chatbot repeating generic advice. Ask for advice, build a meal plan, get instant form coaching on any exercise, or even ask how to use the app itself.
Sport-specific plans
Pick from 38 sports across every category. Strathlon periodises your gym training through structured phases and adapts your week to match days, practice and season. Train at home instead? Home days give you a full session built around that day's focus — Push, Pull, Legs, Shoulders or Arms.
Injury-aware adaptations
Tell Strathlon about an injury and your plan substitutes real alternatives — a lateral raise instead of an overhead press, a face pull instead of an upright row — so you keep a full session rather than a shorter one. Every adjusted move shows an "Adapted" badge.
Photo calorie & macro logging
Snap a photo of your meal and the AI estimates calories, protein, carbs and fat — then adds it straight to your tracker, any day, any meal slot. Or just describe what you ate. In the gym, point your camera at the weight stack, a dumbbell or your logbook and Strathlon reads the number straight into your set.
Day-aware nutrition
Targets that flex with your day — training, rest, match or sport — with an automatic calorie bonus based on the sport, session length and how hard you actually play. Add a walk, run or any of 41 gym-class types — from Spin and Body Pump to Yoga — and your allowance adjusts. Burn estimates stay deliberately conservative, so your results are real rather than flattering.
Cycle-aware training
For those who want it, Strathlon tailors your training and nutrition guidance to your menstrual-cycle phase — worked out privately on your device, never shared, and entirely opt-in.
Live workout timers
Warm-up, rest and HIIT countdowns with spoken coaching cues that keep running on your Lock Screen and in the Dynamic Island — so you can put the phone down between sets. Got an Apple Watch? Your live workout — heart rate, current set, countdowns — shows on your wrist free for every watch owner; driving it hands-free from the wrist is premium. Trained away from the app? Mark the session done in a tap so it still counts.
Apple Health, read-only
Strathlon reads your weight, energy, heart rate and workouts from Apple Health to personalise your plan — all on your device. It never sells your health data.
Progress & celebrations
Track weight, deficit and sessions over time with clear charts. Your plan advances through its phases as you actually train — pausing if life gets in the way — then graduates from fat loss into a structured maintenance phase with a gradual reverse diet.
AI progress insights
A free 0–100 Readiness score reads your sleep, resting heart rate and recovery every morning — no subscription needed. Subscribers get more: your weekly and monthly review opens with an AI-written summary of your week, key numbers bolded; when your weight isn't tracking your predicted deficit, one tap asks your coach to explain the gap; and "Analyse Strength" reads your real lifting history to tell you how training is actually going.
Evidence-based guidance
Supplement and nutrition guidance tailored to the type of day you're having — with the dose, timing and the why. Education, not a prescription.
No account needed
No sign-up, no password. Your profile, logs and history stay on your device. Your subscription is simply your Apple purchase — nothing else to manage.
Coming soon to the App Store
Strathlon is in final testing. The annual plan includes a 14-day free trial, with subscriptions handled entirely by Apple — cancel any time.
