OCTANE HEALTH: AI-Forward Fitness & Nutrition
Your personal AI coach for workouts, nutrition, and everything in between.
Smart Workout Tracking
Log strength training and runs with detailed exercise tracking — sets, reps, weight, distance, and duration. Track different weights across individual sets, toggle bodyweight exercises, and reorder exercises however you like. Create reusable workout presets so your favourite sessions are always one tap away. When you load a preset, OCTANE remembers what you lifted last time and auto-fills your previous numbers as a starting point. AI-powered progressive overload recommendations analyse your history and tell you exactly when to increase weight, add reps, or take a deload — with confidence levels and reasoning so you understand why.
AI Meal Tracking
Snap a photo of your food and let AI instantly estimate calories, protein, carbs, and fat with a full item-by-item breakdown. Not quite right? Refine the results through a quick back-and-forth chat — adjust portions, swap items, or correct anything the AI missed. You can also scan barcodes for packaged foods or log meals entirely by hand. Build a personal Food Bank of your go-to meals for one-tap logging, and get smart food suggestions based on your eating patterns and macro goals.
Macro Goals & Daily Tracking
Set custom macro targets for cutting, bulking, maintenance, or your own numbers. OCTANE can auto-calculate goals based on your height, weight, age, sex, and activity level, or you can dial everything in manually. Visual progress rings and daily breakdowns show exactly where you stand across calories, protein, carbs, and fat — organised by meal category so you can see how your day is shaping up at a glance.
AI Coaching Chat
Chat with an AI coach that genuinely knows your context — your goals, your workout history, your dietary preferences, and facts it picks up about you over time. Ask for workout advice, nutrition guidance, form tips, or help staying on track. Choose from five preset coaching personalities — Drill Sergeant, Hype Coach, Wise Mentor, Friendly Trainer, or Science Nerd — or build your own custom personality from scratch.
Voice Coaching
Talk to your AI coach hands-free with real-time voice conversations. Get live guidance during workouts, ask questions mid-set, or have a proper coaching conversation without touching your phone. Pick from multiple voice options to find one that suits you.
Apple Health Integration
Sync steps, active calories, distance, weight, sleep, heart rate, resting heart rate, VO2 max, and more. Workouts automatically write back to Apple Health with full duration data. Two-way weight sync keeps everything consistent across apps. Sleep tracking pulls in detailed stage data so your coach has the full picture when making recommendations.
Personalised From Day One
A quick onboarding quiz captures your goals, experience level, training preferences, and dietary needs. OCTANE uses this to tailor coaching responses, workout recommendations, and nutrition suggestions specifically to you. Over time, it learns more about you from your conversations and builds up a profile of facts — things like injuries, preferences, and habits — that you can review and edit at any time.
Plan & Forecast
View your workout history on a colour-coded monthly calendar. See a 7-day forecast of upcoming sessions based on your preset rotation, and swap days around as your schedule changes. Tap any day to see a full breakdown of what you did — exercises, sets, weights, and run data.
Share & Export
Generate share cards for workouts, meals, or full day summaries and send them to your mates. Download your complete workout history as a CSV anytime, your data is always yours.
Whether you are just getting started or chasing a new PB, OCTANE adapts to you. Join today and see what AI-powered coaching actually feels like.

Ratings & Reviews

New
• Customisable health dashboard: Pin up to 5 metrics in hero, featured, or compact slots. Browse the rest by category (Activity, Sleep, Heart & Recovery, Body Composition, Vitals).
• 10 new biometrics from Apple Health, including REM / Deep / Core sleep stages, HRV, resting heart rate, and more, all available to your AI coach for personalised guidance.
• Set by set workout tracking. Tick off sets as you go, with a built in rest timer you can extend, shorten, or skip, and a strong haptic when your rest is up.
• Smarter Workout form. Weights backfill from your last session, so you don't start at "BW" every time.
Better
• Today's session card respects an in progress workout — tapping it picks up where you left off instead of starting a new one.
• Planned presets show their exercises inline on the dashboard.
• Logging a meal on a past or future day now uses the day you're viewing, not today.
• Faster, smoother health charts with a sliding tooltip and dynamic Y axis.
Fixed
• Setting a meal ingredient to 0 servings now removes it cleanly instead of erroring on save.
• Save reliability on flaky connections, mutations queue locally and sync when you're back online.
• Lots of polish across charts, finish workout prompts, progress bars, and the sleep summary.
