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.

- Jul 13, 2026 42.5## ✨ Highlights ### 🌍 Local Mean & Solar Time Support Introduced advanced time synchronization options for users interested in astronomical and local geographic time: * **New Time Options**: You can now select between **System Time**, **Local Mean Time (LMT)**, and **Local Solar Time (LST)** directly from the Time screen. * **LMT Calculation**: Automatically calculates time based on your exact longitude (1° = 4 minutes offset from UTC). * **Local Solar Time**: Uses the `adhan2` library to calculate the "True Solar Time" based on the sun's actual position (Equation of Time). * **Watch Synchronization**: When you press "Send to Watch" or when the app syncs automatically, it now respects your selected time type, allowing your G-Shock to display LMT or LST. * **Persistent Settings**: Your time type selection is securely stored in the watch's internal "scratchpad" memory and persists across sessions.

### ℹ️ Educational Info Dialog * **Interactive Info Button**: Added a new information button next to the time zone selector with clear, brief explanations of what each time type represents. * **Multilingual Support**: Updated the info dialog and instructions with full translations for **11 languages**, including Arabic, Bulgarian, Catalan, Chinese, French, German, Hungarian, Japanese, Russian, and Spanish. ### ⚙️ Enhanced Automation & UI * **Automatic Action Saving**: Removed the manual "Send to Watch" button in the Actions screen. Settings are now saved automatically in the background 3 seconds after a change is made, or immediately upon leaving the screen. * **Simplified Instructions**: Streamlined the connection screen instructions across all languages, making it easier to understand how to pair and run actions. * **UI Spacing**: Improved the layout of the time screen with better spacing for easier interaction. ### 🛠 Reliability & Performance * **Connection Stability**: Added a brief 0.5s safety delay during the connection handshake to improve reliability with certain watch models. * **Real-Time Offset Clock**: The on-screen clock now dynamically updates to show the selected LMT or LST in real-time. - Jun 30, 2026 42.3New release 42.3
