You confirm you're okay once a day. If you don't, your emergency contacts are automatically notified. That's the whole idea — here's exactly how Lunio does it.
A daily safety check-in app works on a simple principle: you set a recurring interval — once a day, every two days, every three — and confirm you're fine with a single tap when your window opens. If you miss it, the app automatically notifies your emergency contacts by email or SMS. No GPS. No panic button. No one needs to do anything — your silence raises the alarm.
This makes it useful in exactly the scenarios where other safety tools fail: situations where you're unable to call for help, not just situations where you choose to. A missed check-in could mean you fell, you're unconscious, you're in an accident — and Lunio alerts your people automatically, without you having to do anything.
From setup to a missed check-in — here's the full flow.
Create an account, choose your check-in interval (24h, 48h, or 72h), and add your trusted contacts. Contacts receive an invitation email and must confirm once before they can be notified.
Lunio sends a push notification before your check-in window closes — at 3 hours, 1 hour, and 15 minutes before. You won't accidentally miss one while distracted.
Open the app and tap once. That's the check-in. A new window immediately opens for the next cycle. The whole thing takes about two seconds.
If you don't tap in time, a 60-minute grace period begins. You can still check in and cancel all alerts during this window — no contacts are notified yet.
If the grace period expires without a check-in, each of your contacts receives an email — including the custom message you wrote when you set them up.
On paid plans, an SMS is sent to contacts with SMS enabled — roughly 10 minutes after the email. This second layer ensures the alert doesn't go unread.
Works automatically. You confirm you're okay each day; silence triggers the alert. Protects against scenarios where you can't call for help — unconscious, injured, incapacitated. No GPS. Free to start.
Requires you to press it when danger strikes. Effective for sudden, conscious emergencies — but useless if you can't reach your phone or don't know danger is coming. Reactive, not passive.
Share your GPS position in real time. Useful when location matters for a rescue. Trades privacy for visibility — your coordinates are collected continuously. See our full comparison.
Built-in, useful for acute emergencies. But they require you to initiate the check, share your live location, and aren't designed for daily passive use. Lunio runs continuously on a schedule you set.
Beyond the daily check-in, Lunio includes a Safety Timer for activities with a defined end time.
Start a timer before a solo hike, a late-night run, a drive through somewhere unfamiliar, or any activity you want a hard deadline on. Set the duration. If you don't check back in before it expires — cancel it when you're safely done — your contacts are automatically alerted.
The Timer is available on all paid plans. It works independently of your regular daily check-in schedule — you can use both at the same time.
Free to start. Works on iOS and Android. No location tracking.
Not an emergency service. Best-effort notifications.
