Hot & Cold UI

Ephemeral Drops
Set an expiry. Some memories are meant to disappear.
Feel the Temperature Change
As you walk toward a hidden drop, your entire screen transforms. From frozen icy blue when you're far away, warming through purple and orange, until you're burning red and finally — the screen catches fire.
FAQ
The Rules of
the Radius.
A private hunt works best when everyone understands the magic and the boundaries.
Private by default
No public feed, no follower counts, no map of your memories.
No map hunting
The hunt is compass, temperature, and instinct.
Precise location
GPS powers creation, proximity, and unlock verification.
Controlled media
Drop media is meant for creators and verified finders.
What is Radius?+-
Radius is private, link-based digital geocaching. You hide a photo, video, or note at a real-world spot, share a link, and the recipient walks there to unlock it.
Do hunts use a map?+-
No. Radius is built around a compass and a hot-and-cold proximity screen. The closer you get, the warmer the interface feels.
How close do I have to be to unlock a drop?+-
Easy Mode drops unlock when the hunter is within 15 feet of the target location and the location check is verified.
Who can see a drop?+-
Radius has no public feed or follower graph. Drops are reached through direct links, and unlocked media is intended for the creator and verified finders.
What are Couple, Group, and Anyone modes?+-
Couple mode is for one person, Group mode is for private group chats, and Anyone mode is for broader links like events or creator hunts.
What is Hard Mode?+-
Hard Mode adds a riddle and reference photo. After reaching the area, the hunter photographs the clue object so Radius can confirm they found the right thing.
Can drops expire?+-
Yes. A drop can disappear after 24 hours, 48 hours, 7 days, or stay available with no expiry. Expired drop media is designed to be removed from storage.
Why does Radius need location access?+-
Location is the core unlock mechanism. Radius uses it to lock drops to GPS coordinates, guide active hunts, verify unlocks, and optionally notify you when you are near an active hunt.
