# Cluster for iPhone

Version 2.2 introduces Cluster’s new connected-circle logo and includes the private Shared Space for photos, short videos, and documents. Open a Cluster on Home and tap **Shared Space**. Each item is limited to 50 MB; the uploader or Cluster creator can remove it.

Open `Cluster.xcodeproj` in Xcode 26 or later. Select your Apple Developer team under **Signing & Capabilities**, update the bundle identifier if needed, then run on an iPhone or Simulator.

The app is written in SwiftUI for iOS 17+ and includes private member credentials, QR and link invitations, persistent group chat, offline outbox retry, encrypted Nearby fallback, timed and place-based check-ins, temporary precise or approximate location sharing, a shared map, place alerts, hold-for-help SOS, local notifications, and Check-In Live Activities for the Lock Screen and Dynamic Island.

Nearby communication uses Apple's peer-to-peer Bluetooth and Wi-Fi transport while Cluster is open. Remote push delivery requires an Apple Push Notification service key and production server configuration; the included build uses local notifications plus foreground refresh.
