Reps: HRV Recovery Coach
Readiness, Workouts & Sleep
Free · In‑App Purchases
Know when to push or recover. Reps connects your health signals, workouts, meals, and sleep with a clear readiness score and coaching that fits your day.
Reps brings health, nutrition, and training together so you can decide what today calls for—push, recover, or simply keep moving.
Readiness that makes sense
When your health signals are available, Reps combines HRV, sleep, resting heart rate, and recent training load into a clear score with a plain-English reason. See the trends behind it, then choose your next step.
Train with context
• Build or follow a plan that adapts to how recovered you are.
• Log sets quickly, review your progress, and see which muscles need attention.
• Get recovery guidance before and during a workout.
• Keep your workout state aligned across iPhone and Apple Watch.
• Share completed workouts and routes when you choose.
Eat and hydrate with less friction
• Log meals from a photo or description.
• Track calories, macros, water, and caffeine in one place.
• Review your day with a photo timeline and clear remaining targets.
Ask Rex
Rex is your personal coach for training, recovery, and meals. Ask about your own history and get guidance grounded in the data you choose to share.
Your data, your choices
Health screens leave gaps when nothing was measured. Optional coaching asks before health data leaves your phone, and you can revoke access later.
Start free. Reps Pro adds unlimited AI coaching, full readiness history, and advanced recovery insights.

more As one of the original purchasers of the app, I’ve seen the growth and improvement of the app. This recent UI switch caught me off guard, but it’s a testament to the app developer’s commitment to the upkeep of a great product. I love the nutrition features (snap to analyze, descriptions to help the model understand what you ate, etc) and the summaries are top tier. I love the workout generation features and the way it takes into account you Apple Health information as well, too get the full picture of your health and wellness. I couldn’t ask for a better app!
Developer Response Thank you for your support and feedback! Love reading stuff like this. Means a ton for sticking around and please do send any feedback or feature requests you may have! I’m always looking to improve the app :)

Reps works very well. The health insights are great, and I find the health report to be very helpful. The dev is very responsive to bug fixes and ideas, and does a wonderful job. My favorite thing about reps is it is a place that conglomerates all of the data my Apple Watch is creating and turns it into useable information for me.
Developer Response Thank you for this incredible feedback! Much appreciated and as always, feel free to reach out if you have any ideas or suggestions :)

Reps has a refreshed look for iOS 27. Today, Nutrition, and Workout now make better use of iPhone Duo and wider screens, with your next action beside the charts and history that explain it.
Rex’s advice now matches your current coaching context and your chosen Friendly or Savage voice. Recovery and Energy are clearer, and Body Battery follows your waking day across midnight. Reports lead with useful insights and show recorded trends without filling gaps. You can choose the model that prepares your health report, including Gemini when available.
Widgets and water tracking are cleaner and easier to use.
1.3.9 Sep 21
A clearer day with Reps.
• Rex leads a refreshed Today page with matching glass cards and a roomier layout.
• Today's health readings load before older history, with previously loaded readings preserved during interrupted refreshes.
• Clearer recovery when returning to a subscription.
• Easier meal analysis and review, including menu dishes before logging.
• More readable Rex replies and clearer retry options for conversations and health reports.
• Simpler setup, with connecting Health remaining optional.
• Walking heart rate views for 30 days, 90 days, and six months show recorded readings without filling missing days.
1.3.8 Sep 14
Make Today yours. Choose Health, Nutrition, Training, or Everything and see your plan and next useful action first.
Training is easier to follow, log, and resume, with clearer set details, recovery guidance, rest alerts, and better continuity between iPhone and Apple Watch. Weekly Plan now reflects sessions you actually completed, including those logged outside Reps.
Nutrition is clearer, with visible food names, faster search, reliable multi-photo selection, and hydration shortcuts that use your own container sizes. Meal photos keep their natural proportions throughout review and details.
iCloud Sync now reports its status reliably, and Apple Music is easier to connect from Profile.
Rex conversations, generated workouts, templates, progress photos, sharing, and purchase access are easier to manage. We also improved accessibility, reliability, and performance across the app.
1.3.7 Sep 5
Share your wins. Hit a new personal best or a streak milestone and Reps builds you a trophy card worth posting, with your muscle map on it.
Your ECG, explained. Readings now come with a plain-English read on what they mean, and Rex can talk them through with you.
A cleaner Settings. Everything is grouped where you'd expect it.
Faster where it mattered. Personal-best history, glucose and progressive-overload screens open smoothly instead of stalling.
Fixes: weight screens no longer freeze when your units are set to kg, text stays readable at larger sizes, and coaching features connect more reliably.
1.3.6 Jul 24
• Caffeine tracking you can trust — totals now match everywhere, logs never go missing, and a double-tap won't log twice
• Richer dashboard — a new 7-day stress trend and smoother, easier-to-read graphs on every card
• One less thing to type — Reps now reads your sex from Apple Health
• Gentle reminders before your free trial ends, and easy fixes if a payment ever hiccups
• Smaller, faster app — plus polish and reliability improvements throughout
1.3.5 Jul 17
Share Your Workouts to Strava
You can now post your Reps workouts straight to Strava — connect once in Settings and share your training with your crew.
Also in this update:
• A cleaner Today screen that gets straight to your readiness.
• Log sets by voice or by tapping your gym machine — hands-free, mid-set.
• Find any exercise fast, even when you don't know its exact name.
• Kinder, clearer guidance when a metric is still warming up.
• Faster insights and a more polished look throughout.
• More reliable overnight refresh, so your morning numbers are ready when you are.
Thanks for training with Reps. Questions or ideas? Tap "Something wrong?" in the app — we read everything.
1.3.4 Jul 6
Your AI coach, reimagined — and a big update to how you train, eat, and share.
Rex, your coach, is now one tap away from anywhere in the app, asks before it sets a goal or logs a meal, and lets you see and edit everything it remembers about you. Its replies are sharper and no longer cut off mid-thought.
Supersets that actually flow — pair exercises and Reps moves you through them set by set, back and forth, then rests only between rounds. Start a run or walk in a single tap, indoor or outdoor, with a live route map, heart rate, and splits. Start a workout on your phone and finish it on your Apple Watch. Active workouts now live in the Dynamic Island and on the Lock Screen. And when you finish, share it as a collectible card — the same clean look as your meal cards.
Your meals are collectible cards too, with a brushed-silver edge and rarer tiers for standout plates — share them as a still or a gently moving video. Food logging is instant now: the card appears right away and fills in while you carry on, and search finally finds brand-name and packaged foods. Your coaching reflects only what you've actually eaten so far, not meals you've pre-logged for later.
New Cardio Recovery shows how fast your heart settles after a workout versus your baseline. Training Load gets a calmer, full-screen redesign. Sleep and energy screens are easier to read, and the whole app wears a deeper, more consistent look.
Plus a wide accessibility pass and lots of small fixes: workouts you didn't start no longer appear, a running session always shows on launch so you can end it, and your stated goal never shows up blank in the coach again.
Thanks for using Reps.
1.3.3 Jun 8
The Insights tab is now your Health Report. Auto-generates on first open with a big grade, AI summary, a freshness chip so you know when it updated last, and an inline checklist of what to work on. A mini-card on Today keeps your grade one glance away.
Every metric gets Apple Health-style charts. Tap any number for day / week / month / 6-month / year views with a dashed average line, soft range band, and tap-to-select tooltips. Steps shows hourly bars for the day and daily bars for the week.
Rex Cloud coach stays on — fixed the cold-launch "cloud unavailable" bug where it'd quietly fall back to on-device. Now retries automatically on network blips. Long-press the Reps icon for a "Something wrong?" quick action.
10 new Home Screen widgets with tailor-made visualizations — HRV variability bars, Body Battery as a real battery, Sleep as the actual shape of your night. Caffeine widget decays correctly through the day.
Smarter meal reminders. Reliable overnight refresh. Fewer crashes, snappier app.
