Features & Capabilities

Ham Clock is a specialized Chrome extension designed for portable amateur (HAM) radio operators. It provides an easy-to-read display of both local and GMT (UTC) date and time, along with up to four customizable user notes fields. These notes help operators track locations, QTH locator, callsigns, activation details (like for SOTA, WCA, WFF), and event-specific information.

With a large font and high contrast suitable for bright daylight conditions, Ham Clock supports light and dark themes and offers configurable date/time formats, including seconds. It also includes a helpful reminder every 10 minutes to transmit your callsign, adhering to regulations in some countries. User notes can be saved, shared as JSON-formatted text files (.hctxt), and imported easily through Gmail or Google Drive. Privacy is prioritized—this extension collects no personal data and contains no ads, making it a reliable and user-friendly tool for the HAM radio community.

User Reviews

Ham Clock is a well-designed, simple app that effectively displays local and UTC times simultaneously, favored by ham radio operators for its clear interface and being ad-free. Users appreciate the included timers and notes feature. However, multiple reviews highlight the absence of seconds display, lack of widget support for quick home screen access, no 12-hour clock option, inability to input manual times, and missing audible timer alerts as notable drawbacks.

Pros

Displays both local and UTC time simultaneously, which is valuable for ham radio use.
Simple, clean, and easy to read interface, especially useful in the field.
No ads and free to use, making it accessible and non-intrusive.
Includes useful features like timers and a notes section that add value beyond basic time display.
Well configured for the core purpose without unnecessary extra features, appreciated by users.

Cons

Lacks the ability to display seconds alongside hours and minutes, which some users need for precise timing.
No widget support, making quick UTC time reference on home screen impossible.
No 12-hour clock mode option, only 24-hour format is available, which confuses some users.
Cannot enter manual time adjustments, limiting logging accuracy for contacts made earlier than current local time.
No audible alerts or notifications for timers, such as at the ten-minute mark.

Recent reviews

An amazing logger would be nice if it was able to sync my logs on laptop to my hamrs app on cellphone it would just be nice no matter where you have hamrs downloaded that it could sync so if you don't have your computer you can still see all your logs on you cell or other devices

Good. But we need an option to enter the time because we might have contacted earlier than the current local time and want to know the UTC time. Anyway this is useful.
