What it does
An SOS alert app that does a few things well.
No dashboards, no monitoring subscription. One button, the people you trust, and your location when it matters.
- 01
One Tap to Alert
Press and hold the SOS button for 1 second. OneTapAlert gets your location and alerts your trusted contacts. Add a short message or photo if you have time.

Share Your GPS Location
Contacts get a private link to a live map that refreshes every 10 seconds while you share. The link stops when you press Stop, and expires after 24 hours.
Learn more - 03
Notify Trusted Contacts
Choose up to 3 people. They don’t need OneTapAlert installed — an alert arrives as an email, and on paid plans as texts and a phone call.

Safety Timer
Set a check-in timer for a walk, a date or a late shift. If you don’t turn it off in time, OneTapAlert alerts your contacts from our servers — even if your phone is off.

SMS & Voice Notifications
On a paid plan, contacts also get text messages and an automated phone call from +1 877 405 9946, so an alert is hard to miss.

How it works
Set it up once. Use it with one hold.
- Prepare your trusted contacts. Add up to 3 people with their email address, and a mobile number if you want texts and calls on a paid plan.
- Activate SOS when you need help. Press and hold the button for 1 second. OneTapAlert gets a GPS fix and starts sharing your location.
- Your contacts are notified. Everyone gets an email with a live location link. On a paid plan they also get text messages and an automated phone call.
Free
Email alert + live location link
Paid
Adds SMS, an automated voice call and the safety timer
For your contacts
Nothing to install on their end.
The people you add don’t need OneTapAlert, an account or a smartphone app. They need an email inbox — and for paid alerts, a phone that can get texts and calls.
- An email titled “Emergency Alert from” your name, with a button to your live location.
- A private map link that opens in any browser and updates while you share.
- On a paid plan: two text messages and an automated call from +1 877 405 9946, so they know the number.
Who it’s for
For the moments you’re on your own.
Solo travelers
Exploring a new city or hiking alone, with someone back home who can see where you are if something goes wrong.
Older adults and caregivers
A single large button for a parent who lives alone, and a clear alert for the family members who look out for them.
Students
Walking back from the library or a party late at night, with a safety timer that checks in for you.
Lone workers
Home visits, deliveries and site work where nobody else is around. Set a timer for the length of the job.
Night-shift workers
Late commutes and empty parking lots. One hold of the SOS button reaches the people who would want to know.
Outdoor activities
Runs, rides and day hikes. Share your location if you need help; the timer covers the hours you expect to be out of reach.
Know what you’re choosing
A personal alert app, not a monitoring service.
Your iPhone or Android phone already has emergency features, and some apps sell professional dispatch. OneTapAlert does something simpler: it gets an alert and your location to the people you choose, on any phone, without calling 911 first.
How to choose a safety app- Built-in phone SOS
- Calls emergency services first, then texts your emergency contacts. Free, platform-specific features vary.
- Professional dispatch apps
- A monitoring center can send police or medical help. Usually a monthly fee.
- Family locator apps
- Ongoing location sharing within a group that all use the same app.
- OneTapAlert
- Alerts the people you choose with your live location — by email for free, plus texts and calls on paid plans. Contacts don’t need the app.

Privacy
Your location, on your terms.
What is shared
Your GPS position and its accuracy, your name, and any message or photo you add to the alert.
When
Only after you send an SOS or a safety timer you set runs out. OneTapAlert does not share your location in the background otherwise.
With whom
Only the trusted contacts you added. They can’t request your location, see your history or track you outside an alert.
For how long
Until you press Stop. Every location link expires after 24 hours at most. Read the Privacy Policy.
Good to know
What OneTapAlert can and can’t do.
OneTapAlert is not an emergency service. It alerts the people you choose. It does not contact 911 or dispatch help. If you are in immediate danger, call 911 or your local emergency number.
- Your phone needs a data or Wi‑Fi connection to send an alert. There is no offline queue: an SOS cannot be delivered while you are disconnected.
- An SOS needs a location fix. If your phone cannot get one within about 20 seconds, the alert is not sent and the app tells you.
- GPS accuracy depends on your device, location permissions, surroundings and signal.
- Email, SMS and phone calls are delivered by third-party networks and can be delayed or fail. Contacts are not guaranteed to see or respond to an alert.
- SMS and call delivery outside the United States depends on carrier coverage at the destination.
Do my emergency contacts need to install OneTapAlert?
No. Contacts receive alerts by email — and on a paid plan by text message and an automated phone call too. The location link opens in any web browser, with no app or account needed.
Does OneTapAlert call 911?
No. OneTapAlert alerts the people you choose; it does not contact emergency services or dispatch help. If you are in immediate danger, call 911 or your local emergency number first.
What does the free plan include?
SOS email alerts to up to 3 trusted contacts, with a live location link. Text messages, automated voice calls and the safety timer are part of the paid plans. Compare plans.
Can my contacts track me whenever they want?
No. Contacts only see your location after you send an alert, through a private link. Sharing stops when you press Stop, and the link expires after 24 hours at most.
What happens if I have no signal?
An SOS needs a data or Wi‑Fi connection to send. There is no offline queue, so an alert cannot be delivered while you are disconnected. A safety timer you already started is the exception: it runs on our servers and still alerts your contacts if it expires.
Be Ready Before You Need It.
Set up your trusted contacts in a few minutes. The free plan sends SOS email alerts with a live location link. No credit card needed.
