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.

The short answer
Whoop if you want a dedicated sensor worn all day and continuous strain.
RestUp if you want the recovery reading without a second device, account or cloud.
RestUp asks for

The watch you already wear, and this app.

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.

WhoopCannot use an Apple Watch as its sensor. Its Apple Health integration imports workouts and writes data out, so a Whoop is always an extra device.
RestUp Today: readiness 78 of 100, today’s movement, and seven days of recovery signals.

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.

WhoopRequires an account and a paid membership; data lives in Whoop’s cloud. Its App Store label links health, location, contact and identifier data to you, including for the developer’s own advertising.
Where your data livesAll of it stays on your phone.
History, settings and remindersKept on your phone. Google backup doesn’t copy them, so RestUp starts fresh on a new phone.
Your health dataNever leaves your phone.
No accountNo sign-up, no email

Read onlyNever changes what your watch recorded

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.

WhoopWe could not find a chronotype in Whoop’s documentation.
RestUp chronotype: Bear. You sleep when it’s dark and wake with the light. Usual bedtime 10:30 pm, usual wake 6:30 am, bedtime drift about 33 minutes.

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.

WhoopBuilt around Strain, a 0–21 score that runs all day, next to Recovery and Sleep.
RestUp Sleep: Rested, 7h 51m, woke up 3 times. Sleep score 98 of 100. HRV overnight 59 ms, near your 60 ms baseline.
In fairness

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.

What about Apple’s own score?On a Series 12 or Ultra 4, try it before paying for either.

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?

Pick Whoop if

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.

Pick RestUp if

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.

If it is Whoop’s yearly cost, see every alternative
