Roadmap
Live positions, ten days of stays and journeys, named places of three kinds, and per-person sharing.
One to one, with receipts done properly, and a copy kept on your phone or in your own Google Drive — your choice.
Voice and video, phone to phone or through Radius's relay. Ring with the app closed and on the lock screen with Answer and Decline; Bluetooth headsets; the call survives switching apps and the screen sleeping; tuck it away and use the app.
The watch reports on its own and the map follows whichever device you actually have.
Spoken directions to a person or a saved place, with turn arrows, a full route list, and rerouting. Runs on Radius's own routing — no mapping company, nothing per trip.
The map and your messages in a browser, with two-factor sign-in from an authenticator app.
Conditions under each person from the National Weather Service, and a loud word when a warning or watch covers someone you can see or comes within ten miles of them.
Name your people; each is a seat when they sign in. Up to five on the $1.99, six to ten for $2.99.
Who arrived where and left where, and when; each person's history; severe weather — in any browser, for the family member without an Android phone.
Optionally show the track you are playing under your name — with no account connected to Radius. Tap it to open it in your own player.
Every place says who it is shared with. Take any of theirs off your map. Be told when somebody arrives at or leaves a place you both share — per person, per place, arrive and leave separately.
The free month is your family plan from day one. Add people by email or phone; they are linked and on the plan the moment they sign in. Families can grow into families. Family Plan $1.99 a month for four; Family Plan+ $2.99 for up to ten; $9.99 a year for one more.
Conversations you chose to keep in Google Drive load back into the app as you scroll past the two-week mark — so a backup is something you can actually read again.
Turn-by-turn now runs on a nationwide routing build — all fifty states, on Radius's own server.
Radius runs on iPhone in the lab today: same account, same map, same family plan, same server. Being rebuilt on Apple's own plumbing before release: background location, calls that ring on the lock screen (CallKit), uploads. Android can be installed from this site while we wait for stores; an iPhone cannot — which is why the App Store comes first.
End-to-end encryption for messages and photos, before the store releases: conversations sealed with keys that live on your phones, never on the server — so nobody who breaks into a server, including us, can read them. The groundwork (per-account keys, a recovery phrase, new phones let in by your old one) is already built into the server's design.
After the App Store. Measured against Play's policies line by line already: a Play build without the self-updater (Play updates itself), the background-location disclosure and its review video, the data-safety form, and buying through Google Play in that build — the plan and prices stay the same. The direct download here stays either way.
Key storage is already built; the encryption is not yet wired up.
