How it works

Wear it tonight. Read it tomorrow.

Tonight
Wear your watch to bed
An Apple Watch, or a watch that writes your sleep to Health Connect on Android.
Tomorrow morning
Wake up to one number
A readiness score out of 100 and a plain line on why, before you get out of bed.
Every Sunday
Read your week back
The weekly digest: your best and hardest nights, and one thing to try.

What it’s for

Your watch collects the numbers. RestUp tells you what they mean for today.

Most sleep apps hand you charts. RestUp reads them for you, compares them with your own normal, and says it in a sentence you can act on before breakfast.

Each morning“Should I push or rest today?”

Know whether to push or rest, before you get out of bed.

One readiness score out of 100, with a plain line on why. It weighs last night, your heart and your recent training against your own last two weeks, so a low number means low for you.

a sentence

Sleep screen: “Rested, 7h 51m, woke up 3 times”, sleep score 98

Last night“I slept eight hours. Why am I tired?”

Understand your sleep, instead of just counting it.

Deep, light and REM in plain words, how often you woke, and your overnight heart and breathing next to your own baseline. Then the part that matters: what it adds up to.

Movement“Was today’s walk a lot, for me?”

See whether today’s effort fits your usual.

Every walk, run and hike gets its own page, set against how long and when you usually do it. On a take-it-easy morning, RestUp suggests something gentle instead.

You screen: “Your patterns”, chronotype Bear

Your patterns“What actually changes my sleep?”

Learn what actually changes your sleep.

Over a few weeks RestUp finds patterns in your own nights: your chronotype, how you bounce back after hard days, what goes with your bad nights. Each finding shows the nights it came from.

The RestUp almanac, Chapter I: Where it began

Over weeks and months“Am I actually getting better?”

Look back and see how far you’ve come.

A weekly digest every Sunday morning reads your week back to you. Every two months the almanac writes a new chapter from your last six months, and your best runs become keepsakes.

The almanac: your last six months, two months a chapter, kept on your phone
Keepsakes for a calmer heart or your best night yet

A note from the person who makes it.

tap a highlighted phrase to see it in the app

Hi, I’m Aman.

RestUp: Sleep Recovery Tracker is an app for iPhone, Apple Watch and Android. Each morning it takes the sleep, heart rate and heart rate variability your watch recorded overnight and turns them into one readiness score out of 100. It keeps a running tally of the sleep you owe from the last seven nights, checks your HRV against your own 14-night average, and works out your chronotype from the hours you sleep. Your phone does all the math, and you never make an account.

Questions people ask

Before you download.

short answers, from the person who makes it

Do I need a Whoop band, a ring or a subscription?

No. RestUp works with the watch you already own and is free to download. Your morning readiness, last night’s sleep, sleep insights, the widgets and the Apple Watch app stay free. RestUp Plus is optional: it adds workout pages, findings, night experiments, the weekly digest, the almanac and keepsakes. Its first week is free, and the store shows the price.

Which watches work with RestUp?

On iPhone, Apple Watch. RestUp reads Apple Health, so another watch or ring that saves your sleep and heart rate there works too. On Android, any watch or band that writes sleep and heart rate to Health Connect, such as Wear OS, Samsung, Fitbit and Garmin. The watch app and complications are Apple Watch only.

Does RestUp work on Android?

Yes. RestUp is on Google Play and reads Health Connect. You get the same readiness score out of 100, sleep explained in plain words, sleep debt and home screen widgets. There is no Wear OS watch app.

Readiness on Android →

My Apple Watch is older than Series 12. Can I still get a readiness score?

Yes. Apple’s own Readiness score needs a Series 12 or Ultra 4. RestUp works with any Apple Watch that records your sleep in Apple Health and scores your readiness from 0 to 100 against your own 14-night baseline.

Do I need to make an account?

No. There is nothing to sign up for. Open the app, let it read Apple Health or Health Connect, and you’re set. If your watch has been tracking your sleep, your first reading is there today.

Where does my health data go?

It stays on your phone. RestUp works out every score on the device and has no server that holds health data. On iPhone, iCloud keeps your settings; on Android, nothing goes to Google backup. Anonymous app analytics, which you can turn off, are the only data that leaves.

How is the readiness score worked out?

From five parts: sleep balance, recovery, training load, nervous-system balance and consistency. Each is judged against your own recent nights, not a population average, and a part your watch didn’t record is left out rather than guessed.

Does RestUp work on iPhone Duo?

Yes. RestUp 1.2 has layouts for iPhone Duo, on the cover screen when it’s folded and as two-page spreads when it’s open.
