Radius keeps your whole family on one private map, with the safety tools you'll actually use. Send an SOS in seconds. Share your location with anyone, no app needed. Know the moment they land. It's all just $2.99 a month for a family of four, with no ads, ever.
Radius is on Google Play and the App Store. Get the app first: that is where your account is made. Once you have it you can also use Radius in any web browser: sign in on the web.

Seeing a dot on a map is just the start. Tell Radius where you're headed, with Watch me get there. If you haven't checked in by the time you set, your phone asks if you're okay. Still no answer? Your family gets an alert with your location. It even works if your phone dies.
See every safety toolShare where I am
Send a live link to the babysitter or Grandma. They don't need the app, and they only see where you are right now. It can turn off on its own when you arrive.
Press and hold the SOS button and a loud alarm goes off on the phones of the people you picked, and on Android it sounds even on silent. They'll see right where you are. You hold it down and get a 5-second countdown, so a bump in your pocket won't set it off.
Your card shows who checked your location and how often. Want a ping every time? Turn it on for anyone you like.
Radius knows when your loved one lands after a flight and lets you know where. No flight number needed.
If a phone senses a crash, Radius checks in first and alerts the family if there's no answer. Plus speeding alerts and driving reports, all included.

Built for kids, trusted by parents
Kids under 13 can't share anything until a parent says yes with a quick one-minute ID check. It's free, and no credit card is needed. Kids always see when their location is being shared, and a child's data is never sold or used for ads. Parents in two homes? Your child can be on both of your plans.

Why families love Radius
Other apps save the good stuff for pricey upgrades. Life360 Gold is $16.99 a month (App Store prices, September 2026). With Radius, your whole family gets every feature for $2.99 a month, or $29.99 for the whole year. That's about 58¢ a week!
We don't run ads, and we never sell your data. Your family's locations and messages live on our own servers. You pay a small price, and that's how we keep the lights on. See how we protect your data.
Some location apps let partners use driving and location data for things like insurance and retail planning. Radius doesn't do that and never will. Want to compare? Read Life360's privacy policy, then read ours.
