RestUp
vs Whoop
Whoop is a second wearable with its own sensors, its own cloud and a yearly membership. RestUp is software for the watch already on your wrist. If you already sleep in one, this page is for you.

Where RestUp is different.
It reads the watch already on your wrist.
Your Apple Watch, or on Android any watch that writes to Health Connect, already records your nights. RestUp turns them into one readiness score each morning, in plain words, and puts it on your watch face and in the Smart Stack.

No account. Your health data stays on your phone.
Every score is computed on your phone. There is no RestUp account to sign up for or to breach. On iPhone your settings keep a private copy in your own iCloud; your health data never goes into it.
Anonymous analytics about the app itself are the one thing that leaves your phone. You can switch them off.
It reads your chronotype.
After about a week of nights, RestUp tells you whether you are a lion, bear, wolf or dolphin, with your usual bedtime, wake and drift, and shows the nights it read to get there.

Rest-first, in plain words.
RestUp is deliberately not a strain-chasing app. It reads the same kinds of numbers and tells you what they mean for today: rested, near your baseline, a steady day. Rest is strength.

What Whoop gives you that RestUp cannot.
RestUp measures nothing itself. It reads what your watch recorded, so its ceiling is your watch.
- A dedicated sensor worn 24 hours a day, with no screen and no charging break.
- A Strain score from 0 to 21 that runs all day, and a Sleep Planner.
- On higher tiers: Health Monitor, Stress Monitor and a Healthspan estimate; on the MG band, ECG and blood pressure insights.
- A large community, with about 76,000 US App Store ratings.

Whoop facts from whoop.com, support.whoop.com, developer.whoop.com and its US App Store listing, checked 12 September 2026. Whoop membership prices include the band.
From 18 September 2026 those two models ship with a native Readiness score from 0 to 10, included with the watch. Apple lists it for no earlier Apple Watch, which is where an app still has a job. The Apple Watch Readiness guide covers what it leaves out.
Which one should you pick?
You want continuous all-day strain from a dedicated sensor, do not want a screen on your wrist, and are happy with a membership and a cloud account. Its higher tiers include health monitoring an Apple Watch app cannot replicate.
You already sleep in an Apple Watch, or an Android watch that writes to Health Connect, and want the recovery and sleep reading without a second device, a second charger, or a second account.
