Reps vs Whoop
The Whoop alternative that needs no extra band.
Whoop is a great recovery tracker — if you're happy to wear a second device and pay a membership to keep it running. Reps gives you the same morning readiness read from the Apple Watch already on your wrist, then goes further: an AI coach, nutrition, and strength recovery in one app.
Free to try · No hardware to buy
The honest version
Whoop and Reps are trying to answer the same question — how hard should I train today? — from two very different starting points.
Whoop answers it with a dedicated 24/7 sensor: a screenless band you wear on your wrist or bicep, backed by an ongoing membership. That single-purpose hardware is genuinely good at what it does. Reps answers the same question using the Apple Watch you already own. There's no second device to strap on, nothing new to charge overnight, and no hardware subscription — the watch is the sensor.
Where the two really diverge is scope. Whoop is a recovery-and-strain instrument. Reps is built to be the one app that sees your whole training life — recovery, workouts, running, sleep and food — so the coaching you get is drawn from all of it at once, not a slice.

What Whoop does genuinely well
Give it its due
A dedicated band worn around the clock captures data your phone can't when the watch is off the wrist, and Whoop's strain-and-recovery coaching is polished and well-respected. The screenless design is deliberate — nothing to glance at, nothing to distract you. If you want a device whose only job is recovery, and you don't mind paying a membership to run it, Whoop is a serious tool.
Reps isn't trying to out-sensor a purpose-built band. It's making a different bet: that most people who'd consider Whoop are already wearing an Apple Watch every day, and would rather get the same daily answer — plus a lot more — without buying and charging a second gadget.
Five apps' worth of context, one AI coach
Here's the argument that matters most. People training seriously usually end up with a stack: a recovery app, a strength logger, a running app, a food tracker, a sleep tracker. Each one sees a sliver of you. Reps tracks all of it in one place, which means the coach advising you — Rex — is reasoning from your full picture, not a fragment.
Ask Rex "why is my recovery low today?" or "should I train legs?" and it answers from your actual sleep, training and recovery — not canned tips. Where your iPhone supports it, that reasoning runs on-device, so your health data doesn't have to leave your phone. That's a combination a cloud-only recovery band can't offer: the same morning readiness read, plus a coach that has also seen what you ate, how you lifted, and how you slept.
- One Readiness Score every morning from HRV, sleep and training load — with a plain-English verdict, not a wall of charts.
- Training windows that tell you not just if to train, but when your body peaks today.
- A muscle recovery map so nothing gets overworked and nothing quietly falls behind.
- Photo meal logging with allergy alerts — snap a plate for macros, and get flagged if a logged meal hits one of your allergens.
- Caffeine cutoff coaching that tells you when your last coffee starts stealing from tonight's sleep.
Common questions
Is Reps a true Whoop replacement?
For the daily readiness and recovery read that most people buy Whoop for, yes — Reps produces a single morning Readiness Score from your Apple Watch's HRV, sleep and training load. What it doesn't do is replicate Whoop's always-on band, so if 24/7 wrist-off tracking is your priority, that's Whoop's edge. If you'd rather use the watch you already own and get nutrition, strength and an AI coach alongside recovery, Reps is the broader tool.
Do I need to buy any hardware?
No. Reps runs on the iPhone and Apple Watch you already own. There's no strap, ring or band to purchase, and nothing extra to charge. It works with Apple Watch Series 6 or later.
Does Reps have an AI coach like Whoop Coach?
Yes — Rex. The difference is that Rex reasons over your full training picture, including nutrition and strength work, and runs on-device wherever your iPhone supports it rather than sending everything to a server.
What does Reps cost?
