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

The call

The clearest difference is rating: Tether at 5.0 against Construction Calculator's 4.3. Tether also leads on in-app purchases (none vs 5) and update cadence (every 2 days vs every 6 weeks). Construction Calculator's advantage is ratings volume (47 vs 3) and iOS requirement (15.1 vs 17.0). On price, ads and device support there is nothing between them.
