About Casio G-Shock Smart Sync

G-Shock Smart Sync is an unofficial, open-source Android app for G-Shock, Edifice, and Pro Trek watches. It allows you to control your watch, sync data, and configure settings without a Casio ID. It offers a faster, privacy-focused, and more powerful alternative to the official Casio app. Key Features: - No Account Required: Skip the Casio ID login entirely. - Calendar Sync: Push your calendar events (Google, Samsung, etc.) to your watch as reminders. - Auto Timezone: Automatically adjusts watch time when you travel. - Remote Control: Use your watch buttons to take photos, control music, or launch voice assistants. - Alarm Sync: Configure watch alarms easily from your phone. - Phone Finder: Trigger a loud alarm on your phone to find it. Supported Watch Models: The app works with many Bluetooth-enabled G-Shock, Edifice, and Pro Trek models. - Square: GW-B5600, GMW-B5000, GW-B5000, DW-B5600, TRN-50 - CasiOak: GA-B2100, GBM-2100, GMC-B2100, MRG-B2100 - G-Steel: GST-B100 to B1000, GST-W1000, ECB-900 - Edifice: ECB-10 to ECB-2300, EQB-500 to EQB-2000 - MT-G / MR-G: MTG-B1000/B3000/B3100, MRG-B5000/B2100 - Others: ABL-100WE, GBD-100/200, GBD-H1000/H2000, GPR-B1000 Note: While these watches connect, not all specific hardware features may be fully supported yet. App Walkthrough: 1. Connection Screen: Handles the Bluetooth connection via BLE. Connection is typically much faster than the official app (~3.5s vs 12s). 2. Time Setting: Manage your watch's timekeeping effortlessly. Sync your phone's time, timezone, and DST settings to the watch immediately. 3. Alarms: Read and configure the 5 alarms stored on your watch and the hourly signal (Chime). 4. Events (Calendar Sync): Sync your Android calendars to your watch! Pushes events to the watch's Reminder feature. 5. Actions (Remote Control): Turn your watch into a remote control. Assign actions to button presses (Find Phone, Take Photo, Flashlight, Next Track, Voice Assist, Set Prayer Alarms). 6. Settings: Configure app and watch preferences like light duration, power saving, and more.
