XKG Mobile for iOS

TestFlight public beta — invite-only while we stabilise the bridge layer.

Current status

XKG Mobile for iOS is in closed TestFlight beta. We're inviting up to 1,000 testers in waves of 100. The first wave (build 0.1.0-b1) shipped in late June 2026 and is being used to validate the JSONL bridge, search, and provider launchers.

App Store release is targeted for v0.3.0 (Q3 2026), once we've fixed the iOS-specific issues (background fetch, low-memory handling, Files-app integration).
