## What is Tether?

Tether is a short-lived group safety app built for events — stadium nights, music festivals, girls' nights out, school field trips, and any time you need your group to stay aware of each other without a permanent tracking circle.
The host creates an event in seconds: name it, set a geofence radius on the map, and choose how long it lasts. Guests join by scanning a single QR code — no accounts, no contact list upload, no social graph.
During the event, everyone sees each other on a shared map inside the halo. Alerts fire if anyone drifts outside the zone. The host sees a live activity log.
When the timer hits zero, Tether stops tracking and wipes every location breadcrumb from every device. No permanent record. No data sold. No trail left behind.
Key features:
— Instant geofence around your venue
— QR invite — guests join in one scan, no account required
— Live group map with zone alerts
— Auto-wipe: all location data deleted when the event ends
— No marketing use, no data brokers, no third-party trackers
— Battery-friendly: uses OS-level location triggers, not constant GPS polling

## Version history (last 5 releases)

### 1.30 — 2026-08-05

Coloring of guest icons, live radius adjust, persistent perimeter alert, in-app safety pop alert."

### 1.24 — 2026-08-02

Host has reminder of perimeter selection and option to change boundary measurement during a live event.  Option to invite guests to an event via SMS text.

### 1.19 — 2026-07-28

Bigger, smarter, faster.
• Follow mode — the perimeter can now track the host as the group moves, so a road trip or a walk between venues stays inside a single event. When you arrive somewhere and settle for a minute or two, the perimeter automatically locks at that spot.
• Universal QR — the join QR now works with iOS Camera, not just Tether's own scanner. Guests can scan straight from the lock screen.
• Louder SOS — SOS alerts now buzz and play an urgent tone on every group member's phone. SOS can also be manually cancelled once the emergency has passed.
• Cleaner exits — leaving an event now shows the evaporation animation so you can see your breadcrumbs erasing in real time, matching Tether's privacy promise.
• Better boundary detection — status ("in perimeter" / "outside") is now more accurate at small radii and updates faster when you cross the fence.

### 1.18 — 2026-07-21

Safe Status and SOS alert moved in UI for better visibility.  Sizing change to dashboard.

### 1.17 — 2026-07-20

SOS alert correected for an on/off function.  Corrected connection for host and guests when one participant leaves the event.
