Getting started

• Mimi runs on iPhone with iOS 18 or later.
• The first time you open it, you pick a nickname, agree to share your sleep summary with your group, and allow Mimi to read Sleep from Apple Health.
• Mimi needs something recording your nights: an Apple Watch worn to bed, or a Sleep Schedule on your iPhone. Without one, Health has nothing for Mimi to read.

Mimi says “No sleep data yet”

Mimi reads sleep from Apple Health, so it needs two things: permission, and data to read.

• Check permission in iOS Settings → Privacy & Security → Health → Mimi, and make sure Sleep is switched on. Reopen Mimi afterwards — it re-reads Health every time you come back to it.
• Then check the Health app itself has sleep to read. If Health → Browse → Sleep is empty, nothing is recording your nights yet — an Apple Watch worn to bed, or iPhone sleep tracking via a Sleep Schedule, will start filling it in.

Apple deliberately doesn’t tell an app whether you denied read access, so Mimi can’t tell “you said no” apart from “there’s nothing there” — which is why it points you at Settings either way.

“No reading for last night”

Health has nights on file, just not the one that ended this morning — usually a watch left on the charger. Mimi leaves that night blank rather than counting it as zero hours, so it won’t drag your character down.

How Mimi’s mood works

It’s a running progression, not a snapshot of last night. Each recorded night moves Mimi one step:

• 7 hours or more — one step toward wide awake.
• 5 to 7 hours — holds steady.
• Under 5 hours — one step toward passed out.

There are five states, and a night can only ever move you one. Tap the “?” beside the hours on the home screen to see the whole ladder and where you currently sit. The goal is fixed at seven hours for everyone. Nights you missed while Mimi was closed still count the next time you open it.

The hours look too high or too low

Mimi counts a night as the time you were actually asleep between 6pm and noon the next day, and counts overlapping records once — an Apple Watch and a sleep app writing the same night won’t double it. If your total looks roughly double, update Mimi: older versions counted a night twice when two sources recorded it. If it still looks wrong, compare it with Health → Browse → Sleep for the same night; Mimi shows what Health holds.

It says “Offline”

Mimi couldn’t reach its server — usually a weak connection. Your sleep, Mimi’s mood, and Your week all keep working; your group and the leaderboard catch up the next time you open Mimi with a connection.

Cookies and the shop

Mimi’s room starts empty — just her, bare walls and a window — and you fill it from her shop: tap the bag at the top of the home screen, or your cookies beside it. Everything in it costs cookies, and you earn cookies by sleeping:

• 7 hours or more — 10 cookies.
• 5 to 7 hours — 4 cookies.
• Under 5 hours — 1 cookie.
• On a streak — from your third 7-hour night in a row, each one adds 5 more.

Each night pays once, the next time you open Mimi — and nights from the past week that you missed while it was closed still pay. You start with 30 cookies, enough for her first bed. Cookies come from sleeping, and if you can’t wait, the shop sells a plate, a jar or a tin.

In the shop, pick a piece — bed, rug, nightstand, lamp, desk, plant, wallpaper, window, clock, picture, slippers or bunting — and tap a look to try it in her room before you buy it. Anything you’ve bought can go back in for free, or be put away. The lamp needs a nightstand to stand on.

Where are my cookies kept?

Your cookies and her room are kept on this iPhone, with a copy on your account, so reinstalling Mimi brings them back. Delete my data empties them both, and you start again with an empty room and 30 cookies.

Mimi Plus

Mimi Plus is an optional subscription: every room collection and each new one, outfits your friends can see, all your nights rather than just this week, 100 cookies a month, and a rest day each week that keeps your streak after a short night. Sleep, friends, nudges and the base shop stay free.

It’s $29.99 a year after a 7-day free trial, or $4.99 a month, and renews automatically until you cancel. Cancel any time in Settings → your name → Subscriptions, at least 24 hours before it renews. Deleting your data or the app doesn’t cancel it.

If it ends, what’s in her room stays there until you swap it, and anything you bought on its own is yours to keep. A rest day keeps your own streak only: your friends see the real one, and Mimi still feels the night.

Bedtime

Mimi’s night runs from your bedtime to your wake-up time, both set under gear → Bedtime. At bedtime her lamp (if she has one) stays on as a nightlight, and she takes herself off to bed — or, until she has a bed, to a little mat on the floor. She sleeps until your wake-up time, unless you pick her up and take her out of bed; drop her back on the bed to tuck her in. It’s just her routine: her mood only ever follows the sleep Health records.

Her window shows the real sky where you are — sunrise, day, sunset and night — from your iPhone’s time zone. Mimi never asks for your location.

Patting and picking her up

Tap Mimi to pat her. Drag her to pick her up, and let go to put her down. While she’s asleep, a pat is all she’ll notice. With Reduce Motion on, she stays where she is instead of wandering about.

Adding a friend

Tap the gear → Get invite code, then share the six-character code. Your friend opens Mimi, taps the gear → Join a group, and types it in.

• A code works once, and expires after seven days. Generate a fresh one for each friend.
• Shared it too widely? Revoke code kills it immediately, as long as nobody has redeemed it yet.
• A group holds you plus five friends. At the cap, the invite button turns off.

“That code didn’t work”

A code is refused when it has already been redeemed, has expired, the group is already full, or the friend who shared it has since left the group. Check for typos — codes avoid easily-confused characters, so there’s no letter O or digit 1 or 0 in them — and ask your friend for a fresh code if in doubt.

Mimi keeps you in one group at a time

Joining a new group leaves the one you’re in. The app warns you before you do it.

Leaving, and removing someone

Gear → Leave group takes you out immediately: you drop off their leaderboard and they drop off yours. Whoever currently owns the group can also remove any member with the ✕ beside their name. If the owner leaves, ownership passes to the longest-standing member left; when the last person leaves, the group is deleted.

A friend’s row shows “—”, “No reading yet”, or “3 days ago”

Their figure isn’t from last night. Mimi only shares your hours when you open the app (and only once the night is over), so a friend who hasn’t opened it in a while carries their last reading and sinks to the bottom of the board rather than ranking on a stale number.

Sending a nudge

On the leaderboard, tap a friend’s row and pick one of three reactions — go to bed, nice night, or rough one. There’s no typing: Mimi has no free-text messaging anywhere. You can send each reaction to each friend once a day, and the symbol greys out once you have.

I’m not getting notifications

• Check iOS Settings → Notifications → Mimi is allowed.
• The two daily reminders, at bedtime and in the morning, are under gear → Bedtime, where you can change their times or switch either off.
• Nudges from friends always appear in the app on the leaderboard, even if a banner doesn’t arrive.

I can’t find Mimi’s room, the shop, nudges, Leave group, or Revoke code

They arrived in Mimi 1.1. Update from the App Store.

There’s no login — is that right?

Yes. Mimi creates an anonymous account on your device the first time you open it, so there’s no email or password to manage. The trade-off: the account lives on that device. Switching phones starts you fresh, and your old place in a group doesn’t carry over. Deleting the app doesn’t delete your account or your data — use Delete my data for that.

Deleting everything

Gear → Delete my data permanently removes your account, your profile and sleep summary, your group memberships, the invite codes you created, the nudges you sent and received, and your push token. It can’t be undone, and it takes effect immediately. If Mimi says it couldn’t delete your data, check your connection and try again.

What your friends can see

Your nickname, how long you slept last night, which night that was and whether you told Mimi yourself, your streak, which state Mimi is in, and what she’s wearing — that’s all, and only within your group. Full detail is in the privacy policy.
