Are U OK 心连心Not by your side,
still want to know you're OK
Not calling or texting every day doesn't mean nobody worries about you. With Are U OK you tap "I'm OK" on a schedule you set, and the people who care see at a glance that you're fine. Miss one, and it reminds you first, then lets them know.
Introduction video
Why we built Are U OK
In an endless stream of messages, is there a way to care that is calm yet clear at a glance? The simplest, easiest, least intrusive way — without putting your private life online.
My status goes only to the people who care about me;
I follow only the people I choose to care about.
One tap puts them at ease
No daily calls or check-in texts. Tap "I'm OK" at your own pace and your family is notified that you're fine.
Quiet when you're fine, loud when it matters
No chatting, no small talk. Only when a check-in is missed are you reminded first, and your family told after a grace period.
Only for the people who care
No feed, no public posts. Your check-ins go only to the family you added yourself.
Anyone away from the people they care about
needs a way to say "I'm OK"
Not by your side, but still close at heart. Are U OK is for all of these worries.
Older people living alone
Cameras feel like surveillance, yet the family still wants to know they're fine.
Children working or studying far away
Different cities and schedules make daily calls hard.
People with disabilities
Calls and complex steps can be hard — one button says "I'm OK".
Outdoor adventurers & solo travellers
Alone, with patchy signal — family can see at a glance you're safe.
Young people living alone
Illness or an accident can go unnoticed.
Night shifts & solo commutes
Heading home alone late at night, family can't relax.
Chronic illness & recovery
Recovering alone at home, worried about a sudden turn.
Families split by work
Working away from home and worrying about the parents and kids left behind.
Features
Everything centres on one thing — checking in on time — with solid reminders, help and protection.
Scheduled check-ins
Choose every 6 hours, 12 hours, daily, every 3 days and more, with your own reminder time and grace period and a clear countdown; pause guarding when needed.
Overdue alerts, run by the server
Miss a check-in and you're reminded first; after the grace period the server notifies all the family you added by push and email — even if your phone is off, flat or offline.
Emergency SOS
Hold SOS for 2 seconds: your request for help, current location, street address and map links go to all your family at once — even during quiet hours, with no verification step.
Family status at a glance
Progress rings in the family list show whether each person is OK this cycle — who's fine and who's overdue, no chatting needed.
Alert acknowledgement
Family tap "Got it" on an alert or SOS, or acknowledge all at once, so you and everyone else can see who already knows.
One-way sharing, your call
Adding family by OK ID or QR code works right away; they can share back or remove themselves. Email-only contacts confirm by email. Add a contact phone and they can call you with one tap.
Do Not Disturb
Set quiet hours such as the night: no reminders or check-in updates during them, and overdue alerts wait until they end. SOS is never held back.
Care mode New
Enlarge all text and buttons with one switch — right from the top of the home screen — with a shortcut to the system accessibility settings.
Fingerprint / face verification
With Safe check-in on, verify it's you before checking in — fingerprint/face or a check-in passcode; HarmonyOS also offers a face liveness check.
Status, notes and photos
Pick a status, add a short note or a photo when you check in, for a warmer "I'm OK".
Home-screen widget
Shows your nickname and this cycle's deadline on the home screen; tap "I'm OK" to check in without opening the app.
Themes & photo backgrounds
Several theme colours, Frosted glass and Immersive Light effects, plus 6 new photo backgrounds: Sakura, Misty Peaks, Sunset Sea, Bamboo, Starry Night and Wildflowers.
Chat: text, voice, images
On Android, chat one-on-one with family; overdue alerts and "checked in safe" notices appear in the conversation too.
中文 / English
The app, push notifications and emails are available in Simplified Chinese and English, sent in each recipient's language.
Easy for everyone to use
Every notification is text, so Deaf and hard-of-hearing people see it too; Care mode, large buttons, the widget and fingerprint check-in make it less effort.

How it works
First it looks for you, then it waits for you, and only then does it tell your family. Every decision is made on the server.
Check in on time
Open the app on your schedule and tap "I'm OK" to start a new cycle.
Reminder before the deadline
If the deadline is near and you haven't checked in, you're reminded first.
Grace period when overdue
Past the deadline you're reminded again, with time left to check in late.
All family notified
If there's still no response after the grace period, the server notifies all the family you added by push and email.

Privacy & security
Your check-ins are seen only by the people you choose. If we don't need it, we don't collect it.
Shared only with family you add
Check-ins, photos and chats are visible only to the family you added; remove someone any time to stop sharing, or remove yourself when someone adds you.
No location history
Location sharing is off by default; when on, only the latest location is kept, and it's deleted when you turn it off. EXIF and GPS data are stripped from uploaded photos.
Biometrics stay on your device
Fingerprint, face and the HarmonyOS face liveness check all run locally in the system; we never receive any biometric data.
Encrypted, passwords never stored
All traffic uses HTTPS; passwords are kept only as one-way Argon2 hashes.
No ads, no analytics SDKs
No third-party advertising, analytics or recommendation SDKs; we never read your contacts, SMS or app list.
Delete your account in the app
Delete your account right in the app; your account, check-ins, chats, media, location and other data are erased permanently.
