For solo travelers

The solo travel safety app that doesn't track you

Check in once a day when you're fine. Miss it? Your emergency contacts are automatically notified — no GPS, no live location feed, no surveillance.

Lunio is a daily check-in app for solo travelers who want an automatic safety net — without sharing their whereabouts. You set a check-in interval, tap once when everything is fine, and if you miss it, your trusted contacts receive an email or SMS alert. Your location is never collected, shared, or stored. Not once.

Most travel safety apps require you to broadcast your GPS coordinates to a server or emergency contact at all times. Lunio works on a different model: your silence raises the alarm, not your location. That makes it useful for everyday solo travel — and better for your privacy.

Two different models

Check-in app vs. location tracking app

Most solo travel safety apps broadcast your GPS coordinates in real time. Lunio works the opposite way — your contacts only hear from the app when something is wrong.

Lunio — check-in model

You confirm you're okay at set intervals. If you miss the window, contacts are alerted automatically. Your location is never shared. Privacy by default.

Location tracking apps

Your GPS coordinates are shared continuously with a server, a third party, or your contacts. Useful for real-time rescue. Requires giving up location privacy 24/7.

Both models have their place. Lunio is the right choice when privacy matters — or when you simply don't want your every move tracked across a map. For wilderness rescues requiring GPS coordinates, a dedicated emergency beacon is a better fit.

How it works

Your daily routine while traveling

Set it up once before you leave. Takes about two minutes.

Set your check-in interval

Choose daily, every 2 days, or every 3 days. Add your trusted contacts — family, friends, or anyone who should know you're okay.

Tap once when you're fine

One tap each day sends your signal. Push reminders arrive before your window closes — so you never accidentally miss one while distracted exploring.

Miss it? Contacts are alerted

No check-in means automatic email alerts to your contacts. SMS follows on paid plans. You don't have to do anything — silence triggers the alarm.

Built for travel

Everything solo travelers actually need

Safety Timer

Heading out for a solo hike, late-night walk, or an activity with a fixed time window? Start a countdown. If you don't check back in, contacts are alerted automatically.

Works anywhere

Lunio works in any country with an internet connection. Email alerts reach contacts globally. No additional roaming setup needed.

Zero location data

Your location is never requested, collected, or stored — not even temporarily. No GPS permission is needed to use Lunio.

Pause between trips

Back home? Staying with people? Pause check-ins with a single tap — no alerts go out while paused. Resume when you're off again.

Custom alert message

Write your own message that contacts receive when you miss a check-in — include your travel itinerary, accommodation details, or emergency instructions.

Home screen widget

See your check-in status and next due time at a glance from your home screen — no need to open the app. Available on paid plans.

Common questions

About Lunio for solo travel

What is the best safety app for solo travelers?
It depends on what you need. If you want automatic alerts to emergency contacts when you miss a check-in — without sharing your live location — Lunio is built for that. If you need real-time GPS rescue coordination for wilderness emergencies, a dedicated emergency beacon or GPS tracker is a better fit. Lunio is designed for everyday solo travel safety, not search-and-rescue scenarios.
Do I need to share my location to stay safe while traveling alone?
No. Location sharing is one approach, but it's not the only one — and it comes with real privacy trade-offs. A check-in app like Lunio works differently: you confirm you're okay at set intervals, and if you miss one, your contacts are automatically notified. No live GPS feed is needed, and your location is never collected.
What's the difference between a check-in app and a location tracking app?
A location tracking app continuously shares your GPS coordinates with others or an emergency service. A check-in app asks you to confirm you're okay at set intervals — if you don't, contacts are alerted automatically. You stay private until silence raises the alarm. Check-in apps are better for privacy; location tracking is better for real-time rescue coordination in remote emergencies.
Does Lunio work internationally?
Yes. Lunio works anywhere with an internet connection. Check-ins sync even on slow connections. Email alerts are delivered globally. SMS alerts (on paid plans) depend on your contacts' carriers — standard international SMS delivery applies. Your contacts don't need to be in the same country as you.
What is the Safety Timer and how does it help while traveling?
The Safety Timer is a countdown for specific activities — a solo hike, a late-night walk, a first meeting with someone new, or any situation with a defined time window. Start the timer before you head out, set its duration, and cancel it when you're safely back. If the timer expires without you checking back in, your contacts are automatically alerted. Available on all paid plans.
Is Lunio free for solo travelers?
Yes. The free plan includes daily check-ins, push reminders, and email alerts to up to 3 contacts — enough for most trips. Paid plans start at €1.99/month and add SMS notifications, the Safety Timer, a home screen widget, and up to 10 contacts.
