MEET REX — YOUR AI HEALTH COACH
Chat naturally with REX about your health. Ask about yesterday's meals, last week's workouts, or your sleep trends. Choose between three personality modes: Friendly, Normal, or Savage.
HEALTH REPORT, ONE TAP AWAY
The Insights tab leads with your Health Report — big grade, AI summary, freshness chip, and an inline checklist of what to focus on. Auto-generates on first open and streams to your screen. A mini-card on Today keeps your grade one glance away.
10 TAILOR-MADE HOME SCREEN WIDGETS
Each widget designed bespoke for its metric — HRV as 7-day variability bars, Body Battery as a real battery shape draining through the day, Sleep as the actual stage timeline of your night. Plus Readiness, VO₂ Max, Resting Heart Rate, Body Fat, Weight, Training Load, and a live-decaying Caffeine widget. Tap any widget to open its detail view.
APPLE HEALTH-STYLE CHARTS

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 :)
Amazing health insights
DADCØRE
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

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.
