Info Watch Face

A Wear OS watch face for Galaxy Watch Ultra displaying real-time data from Claude AI, Minecraft, and Rust game servers — with battery, date, and time.

Features

• Claude AI Usage Bars — Session (S) and Weekly (W) usage meters pulled live from the Claude API
• Minecraft Player Count — Live query to your Java server via the Server List Ping (SLP) protocol
• Rust Player Count — Live query via Steam A2S protocol with challenge-response support
• Battery — Native WFF BATTERY_PERCENT data source with animated green fill bar
• Time Format Toggle — Switch between 12h (AM/PM) and 24h via the watch face customization screen
• Date — Month and day display
• Ambient Mode — All elements hidden in ambient for battery efficiency

Architecture

Three Android modules:

Module	Package	Target	Purpose
watchface	com.damon1974.infowatchface.face	Watch	WFF XML watch face
wear	com.damon1974.infowatchface	Watch	Complication services + Data Layer receiver
phone	com.damon1974.infowatchface	Phone	Claude/MC/Rust polling + Data Layer sender

Note: phone and wear share the same applicationId — this is required for the Wearable Data Layer API to work.

                                                               watchface.xml (WFF)

Setup

Prerequisites

• Android Studio
• Galaxy Watch Ultra (or Wear OS 4+ device)
• Samsung Galaxy phone paired via Galaxy Wearable app
• Claude.ai account (Pro or Team)

Phone App

1. Deploy the phone module to your phone
2. Open the app and tap Login — log in to claude.ai in the WebView
3. Tap Refresh Now to push data to the watch

Watch

1. Deploy the wear module to the watch
2. Deploy the watchface module to the watch
3. Select Info Watch Face from the watch face picker
4. The S/W Claude bars and Minecraft/Rust counts auto-bind — no manual complication assignment needed

Configuration

Edit these constants in the phone module to point to your servers:

File	Constant	Default
PollWorker.kt	Minecraft host	mcj.thehackpig.com:25565
PollWorker.kt	Rust host/port	rust.thehackpig.com:28017

Protocols

• Claude API — HTTPS to claude.ai/api using session cookie from WebView login
• Minecraft — TCP Server List Ping (SLP) protocol on port 25565
• Rust — UDP Steam A2S_INFO with Valve challenge-response on query port

Development Notes

• git push via WSL hangs silently — push from Windows terminal
• Watch ADB reconnect: run .\connect-watch.ps1
• After changing applicationId, uninstall both packages before redeploying
• WFF BATTERY_PERCENT is a native integer data source (0-100), no complication needed
• Samsung Wear OS only serves SHORT_TEXT for WATCH_BATTERY system provider, not RANGED_VALUE
