Your personal
AI training coach.
Workout Lens turns your Apple Health into a daily training partner. Readiness, an adaptive weekly plan, and a coach you can chat with — all running directly on your iPhone. Nothing leaves the device.
Wake up to your readiness.
Workout Lens turns your overnight HRV, resting heart rate, sleep stages and training load into a single readiness number — and translates that into the day type that actually fits your body: rest, recovery, easy, build or quality.
- Centered readiness ring with semantic status word
- Recovery and Pressure tiles with 7-day sparklines
- Tap a tile for the full detail page with trend charts
- Redesigned sleep view: hypnogram with stage breakdown (Awake / REM / Light / Deep)
- A day timeline — add sleep, workouts and context tags from the + button
- Honest confidence label when overnight data is thin
Your week, planned around your body.
Pick your sport, your goal, your weekly availability — and Workout Lens generates a research-backed schedule with smart session spacing. Long runs anchor the week, hard days never sit back-to-back, and every session comes with a concrete prescription based on your real training history.
- Sport-specific patterns: running, cycling, swim, strength & more
- Hard-easy balance with 48-hour recovery rules
- Multi-week roadmap — swipe past, this week, next
- Tap any day to override the session
- Pace-aware: "11 km easy at 5:30/km" — not generic minutes
A coach in your pocket.
AI Coach Pro understands your last 90 days of training, your sleep, your readiness and your goals — and answers questions like "How was my run today?" or "Am I ready for a hard session tomorrow?" Set your name on the Profile page and the coach greets you personally. The model runs entirely on the Apple Neural Engine. No tokens leave your phone.
- Addresses you by name for a personal feel
- Conversational answers grounded in your real data
- Context tags (caffeine, alcohol, stress, illness) sharpen its advice
- Works offline — even mid-flight, mid-mountain
- iPhone 15 Pro and newer (Apple Neural Engine required)
Every workout, decoded.
Tap any workout and Workout Lens reconstructs the full story: an interactive GPS route, a heart-rate timeline coloured by zone, splits, cadence, lap events and elevation. Every metric you'd expect — plus the analysis cards that tell you what actually mattered.
- Live GPS route map with elevation
- Heart-rate chart calibrated to your personal HR zones
- Splits, lap events, cadence and active energy
- Auto-generated session insights and key takeaway
Drop your workouts into ChatGPT or Claude.
The CSV export is designed for analysis: clean column headers, consistent units, long-format rows. Select one workout or fifty, hit Share — and the file lands in whatever AI tool, spreadsheet, or analytics environment you already use.
- Multi-select with a single tap
- Long-format CSV optimised for LLMs
- Heart rate, GPS, splits, cadence, energy in one file
- iOS Share Sheet — straight to ChatGPT, Claude, Files, Mail
Everything you've done, in one place.
The new Profile tab is your personal home base: lifetime totals, a snapshot of your week, and your latest activity with its route — all in a glance. Set your name here and the AI coach greets you personally.
- Lifetime totals — workouts, training time, total kcal
- "Week in numbers" — avg recovery, pressure and kcal/day
- Your latest activity with its route
- Achievements & records: badges plus fastest 1K → marathon
- Set your name for a coach that speaks to you
See where your body is heading.
The Health info page turns your Apple Health history into clean trend charts. Switch between 30, 90 and 365 days and watch the metrics that matter — from body composition to cardio fitness — move over time.
- Weight, BMI, body fat and height
- VO₂ max, HRV and resting heart rate
- Sleep, SpO₂, respiratory rate and body temperature
- 30 / 90 / 365-day ranges — all read-only, all on-device
Give your coach the full picture.
Tap the + button on the Coach tab to open an Oura-style timeline of your day: sleep, workouts and the context tags you add yourself. Logged a late coffee, a stressful day or a cold coming on? The coach factors it in.
- Sleep, workouts and tags on one timeline
- Tags for caffeine, alcohol, stress, illness and more
- Add with date & time; remove with a long press
- Tags feed straight into the on-device coach's context

Your health data, never elsewhere.
Other coaching apps upload your data to predict what you should do next. Workout Lens decided that's the wrong trade — your readiness, your training plan and even the AI chat live entirely on your phone.
Frequently asked.
Does Workout Lens send my health data to the cloud?
No. Every analysis, every coach response and every plan calculation happens directly on your iPhone. There are no servers, no analytics SDKs and no third-party tracking. Apple Health data is read locally and never transmitted.
How does the AI coach work without an internet connection?
AI Coach Pro downloads a compact language model once after purchase (about 2 GB) which then runs entirely on-device on the Apple Neural Engine. After the initial download, the coach works without any internet connection — including in airplane mode or remote locations.
What does AI Coach Pro cost?
AI Coach Pro is available as an auto-renewable subscription: €2.99 per month or €23.99 per year (the yearly plan saves about 33%). You can cancel anytime through your Apple ID subscriptions, and you keep access until the end of the current billing period.
Which iPhone do I need?
Workout Lens runs on every iPhone with iOS 17 or later. AI Coach Pro chat requires an iPhone 15 Pro or newer for the on-device language model. Workout analysis, exports and the daily coach insights (without LLM chat) work on every supported iPhone.
Can I export my workouts for analysis with ChatGPT or Claude?
Yes. Workout Lens started as a structured workout exporter and that capability is still built in. You can select any number of workouts and export them as a clean, long-format CSV that you can drop into ChatGPT, Claude, Gemini, Numbers, or any analytics tool of your choice.
What happens if I cancel my subscription?
Your AI Coach Pro access continues until the end of the current billing period. After that, the app keeps every workout export feature, the workout analysis screens, and the Apple Health integration — only the personalised daily coach, training plan and chat are paused. You can resubscribe anytime.
Is this medical advice?
No. Workout Lens helps you train smarter, but it is not a medical device and does not provide medical advice, diagnosis or treatment. Always consult a qualified healthcare professional before making significant changes to your training, nutrition or recovery if you have any underlying health condition.
How do I delete my data?
Because there's no account and no server-side storage, deletion is instant: revoke HealthKit access via Settings → Privacy & Security → Health → Workout Lens, or delete the app from your iPhone. Both actions remove the app's local data immediately.
Train smarter,
on a phone you already own.
