Editor's Overview

Casio G-Shock Smart Sync is a calendar & agenda application developed by Ivo Zivkov, packaged as a single Android APK of version 42.9 weighing in at 20.31 MB. The package targets Android 4.1+ and above. Below you'll find the publisher's own description, a quick spec sheet, and a short buyer-beware checklist so you know exactly what you're installing before tapping download.

Install Checklist

  1. Only download through the button on this page — never from third-party mirrors or shortened links, which are the most common way malware spreads.
  2. File size is a light 20.31 MB, so it installs quickly even on modest connections.
  3. This build is signed by "Ivo Zivkov" — always verify the developer name matches what's listed on the app's official store page before installing an update.
  4. After install, Android may prompt you to allow "Install from unknown sources" — approve only this one install, then revoke the permission in Settings > Apps > Special access.
  5. We link directly to the APK file or the publisher's repository; we do not modify the binary. Always run a virus scan after any sideloaded install.

About this app

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

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.
