RestUp
vs Oura

Oura is what most people mean by a readiness score, and the only other app on these pages that reads your chronotype. It is also a ring, a cloud account and a membership. RestUp is an app.

The short answer

Oura if you would rather not sleep in a watch, or want temperature and daytime stress.

RestUp if you already sleep in your watch and want readiness and chronotype with no second device or account.

RestUp asks for

RestUp chronotype: Bear, usual bedtime 10:30 pm, usual wake 6:30 am.

The watch you already wear, and this app.

Oura asks for

An Oura Ring 5: $399 to $499

An Oura account

A membership: $5.99 a month or $69.99 a year

Your data in Oura Cloud, encrypted

Without a membership the app shows only the three daily scores. Oura’s pages, 12 Sep 2026.

Where they agree

More than you might expect.

A Readiness score and a Sleep score, both out of 100.
Built from overnight heart rate, HRV and sleep against your own baseline.
A chronotype estimated from your recorded nights.
An Apple Watch presence and iPhone widgets.

In the app

Where RestUp is different.

Your chronotype in about a week.

RestUp’s chronotype appears after about a week of nights and firms up over two, with your usual bedtime, wake and drift, and the nights it read to get there.

OuraBody Clock needs 40 to 90 days of data.

RestUp chronotype: Bear. You sleep when it’s dark and wake with the light. 46 of 90 bedtimes fell inside the shaded hour.

The watch is the sensor, not a companion.

RestUp reads your Apple Watch directly, so its Watch app and complications are first-class: the watch is where the data comes from. On Android it reads any watch that writes to Health Connect.

OuraThe Apple Watch app shows your scores but does not pair to the ring. It syncs through the iPhone and needs an active membership.

RestUp Today: readiness 78 of 100, recovering well.

A sleep debt you can see.

RestUp keeps a seven-night sleep debt ledger and turns it into tonight’s plan: when to wind down, and whether tonight is the catch-up.

OuraFolds sleep balance into Readiness, but does not show a named sleep debt figure, as far as its documentation shows.

Tonight

10:55 pmLights out · your 8h goalStart winding down around 10:30 pm. A steady lights-out time makes deep sleep easier to reach.

Skip — the late night. You’re 1h 57m short this week, so tonight is the catch-up.

Remind me at 10:25 pm

No account, and no data to sell.

Every score is computed on your phone with no account. Oura says it will never sell your data, and we have no reason to doubt that. The difference is that RestUp never has the data in the first place.

OuraRequires an account and stores data in Oura Cloud, encrypted, possibly processed outside your country. Its App Store label links health, location, contact and identifier data to you.

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

No adsNone anywhere in the app

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.

In fairness

The ring is the reason to buy Oura.

An Apple Watch cannot stand in for it. RestUp needs no new hardware, so its ceiling is whatever your watch records, and its floor is no extra cost.

Comfortable to sleep in, with about a week of battery.
Continuous temperature and daytime stress; on Ring 5, blood pressure signals and nighttime breathing.
Resilience, Symptom Radar, cardiovascular age, cycle insights and an AI advisor.
4.9 stars from about 296,000 US App Store ratings.

On Android, not either-orOura’s app writes sleep, heart rate and HRV to Health Connect, so RestUp can read a ring’s nights there while you keep using Oura’s own app alongside it.

Which one should you pick?

Pick Oura if

You do not want to sleep in a watch, want daytime stress and temperature trends, or want the deepest catalogue of long-term insights and are fine paying for the ring and the membership.

Pick RestUp if

You already sleep in your watch, want readiness and chronotype without a second device or an account, and would like to see how the score is built. Trying it costs a week of wearing the watch to bed, which you may already be doing.
