S2G — Stay 2 Gether — Group-trip companion (iOS 17+, DE/EN)

S2G keeps your crew together on shared trips — live map, push-to-talk voice and group chat in one SwiftUI app. Built for festival convoys, multi-car road trips, theme-park groups and ski tours.

Testing focus:

  • Push-to-talk latency / audio clarity in motion
  • Live-map sync between 2+ devices
  • Onboarding & invite-link UX
  • Background-location accuracy + battery impact
  • iPad layout, CarPlay (if approved)

Looking for: 2+ person crews who can test together. PTT and map sync only shine with multiple devices, but solo testers are welcome for onboarding/UX feedback.

Stack: SwiftUI · iOS 17+ · Firebase Auth/Firestore · LiveKit (PTT) · MapKit · CoreLocation

Privacy: location only during active trips; voice end-to-end encrypted and not stored; contacts never uploaded.

Feedback: please use TestFlight screenshot feedback inside the app.

Quick update on platforms — two things I should have mentioned in the original post:

  • Android version is in active development and will follow shortly after the iOS stable release.
  • Web companion at https://s2g.tausend.net is already live — crew members without the iOS app can join a trip directly in the browser, so a mixed iPhone+Android crew can test together right now.

Looking forward to your feedback!
