About

ClockSync Pro

Read full description

ClockSync Pro keeps your Bluetooth electronic clock accurate with a simple one-tap time sync. How it works: 1. Open the app and tap "Time Auto-Sync". 2. The app scans for your Bluetooth clock and connects automatically (within a range of about 10 meters / 33 feet). 3. Once connected, it writes your phone's current time to the clock. An "OK" confirmation appears when the sync is complete. 4. If no clock is found within 60 seconds, the app shows "Connection Timeout" with a "Reconnect" button so you can try again. Features: - Simple, guided one-tap syncing — no technical skills needed. - Private by design: no account, no sign-in, and no personal data is collected or shared. - Bluetooth connection only. Please note: Bluetooth must be enabled on your phone, and the clock should be kept nearby during syncing.
