Living Alone Safely — So Someone Knows When Something Happens

In 2025, more than 125 million people in China lived alone — young adults in solo apartments, parents their far-away children can't check on, business travelers in hotels. For all of them, the single biggest risk is the same: if something happens, no one knows. This isn't fear-mongering: a sudden illness, a fall in the shower, a kitchen accident — any of these can leave someone living alone out of contact for days.

How a heartbeat check keeps you safe when living alone

TimeWill's approach is simple. You set a check-in frequency — once a day, say — and when it's time, the app reminds you to open it and tap. If you miss the check-in window, the system moves through a sequence: an alert to you first, then a message to your contacts, and finally the option to release passwords and letters. No camera, no smart band, no extra hardware. A phone is all it takes.

• For yourself — Tap in once a day. The day you don't, the contacts you set are notified automatically.
• For your parents — Set it up on their phone and have them check in daily. If you get an alert from another city, you know to call.
• For travel — In an unfamiliar city, shorten the check-in interval so your contacts know you're safe.

Why it beats a smart band

A smart band has to be charged, connected, and worn. Older people resist wearing one; younger people forget to charge it. A heartbeat check is one button — open the app and tap. If an older relative can use WeChat, they can use this. The point: no special permissions, no data collection, no sense of being watched.

Tiered alerts — not all-or-nothing

It isn't 'miss a check-in → alert everyone at once.' TimeWill supports four stages: T1 reminds you, T2 reminds you again and alerts your contacts, T3 releases passwords and account details, T4 delivers final letters. You set the interval for each stage independently, so a missed check-in never turns into an embarrassing false alarm.

How women living alone and older adults differ in what they need

Women living alone tend to worry more about personal safety — break-ins, harassment — while older adults worry more about health events: falls, sudden illness. TimeWill's heartbeat check works for both, but the recommended check-in interval differs: daily for older adults, every two to three days for younger people.

What if I can't check in while traveling?

You can switch on 'leave mode' in the app beforehand — it pauses the check-in for a stretch of time, the way a heartbeat check works, and you turn it back on when you return. The leave expires automatically and detection resumes, so a normal trip never triggers an alert.

Can property management or a neighbor be an emergency contact?

Yes. A contact in TimeWill can be anyone — family, a friend, a colleague, a neighbor. Set at least two, so a notification isn't missed if one person doesn't see it. Contacts don't need to install the app; they receive messages by SMS or email.
