  1. 1Everyone you love on one private map. Each pin is a person, and it moves as they do.
  2. 2One tap for satellite, one for live weather radar, right over your family.
  3. 3The list under the map says where each person is, since when, their battery and the weather there.
  4. 4Tap anyone for their card: where they are now, where they were before, and one-tap Directions.

Safety first

Peace of mind for every kind of day.

Seeing a dot on a map is just the start. Radius helps when it really counts: when someone's running late, when a phone goes quiet, or when a flight should have landed an hour ago.

SOS alarm

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.

Watch me get there

Tell Radius where you're headed. 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.

Share with anyone

Send a live location 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.

See who looked

Your card shows who checked your location and how often. Want a ping every time? Turn it on for anyone you like.

Landing alerts

Radius knows when your loved one lands after a flight and lets you know where. No flight number needed.

Crash detection

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.

See it in action

The real app, with the numbers to match.

Recorded on a real phone. Meet the Derns, our made-up test family. Every clip has numbers pointing at what matters, and under each one, what those numbers mean.

Watch me get there
  1. 1Pick how long, or a place to arrive at.
  2. 2A bar shows Radius is watching, with an I'm fine button, on every screen.
  3. 3Time's up and no check-in? Your own phone asks first. Nobody else is told yet.
  4. 4The bar turns red. Tap I'm fine and nobody is alarmed. Stay quiet and your family is alerted with your location.
Share where I am
  1. 1Pick how long the link lives, or a place it stops at.
  2. 2Send it by text, WhatsApp or email. They need no app and no account.
  3. 3A bar with a countdown and Stop stays on screen while the link is live.
  4. 4What they see: one dot, your name, when it updated, and when sharing stops.
Landed safely, and who looked
  1. 1Radius notices a landing after a flight and tells the family where. No flight number, nothing to set up.
  2. 2Their card shows where they flew from and when they landed.
  3. 3Want to know when someone looks you up? You can be told, one person at a time.
  4. 4Your own card lists who has looked you up and how often.
SOS and missed check-in alarms
  1. 1Someone asked Radius to watch them and never answered: their family gets this amber alarm with their location.
  2. 2Call them, see them on the map, or call 911, right from the alarm.
  3. 3Hold SOS and the people you picked get a loud alarm (on Android, even on silent).
  4. 4I'm safe now stops the alarm and tells everyone.
Live driving and speeding alerts
  1. 1When someone drives, their dot moves along the road live.
  2. 2Their card says Driving, with their speed right now.
  3. 3Well over the limit? The people who can see them get an alert with the speed and the street.
Messages, right in the app
  1. 1A new message pops up with their face, even while you're using the app.
  2. 2Private one-to-one chats with each person, with an unread count.
  3. 3Your reply goes out instantly. The tick moves from Sent to Delivered to Read.
  4. 4Their answer lands in the thread. No switching apps.
Every drive, walk and run
  1. 1The whole family's last two weeks: speeding, hard braking, crashes and top speed.
  2. 2Tap a person for their driving report: top speed, drives and miles.
  3. 3Every trip on a map, with its stops and top speed.

Built for kids, trusted by parents

Keeping kids safe is our top priority.

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.

Other apps save the good stuff for pricey upgrades. Life360 Gold is $16.99 a month. 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!

Your family's data stays yours

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.

We'll never sell your location

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.
