I needed a quick and easy broadcast clock for creating podcast episodes. (There is a great episode of ‘99% Invisible’ on broadcast clocks that is well worth listening to.) While I found a few apps offered for sale, nothing really did the trick. To solve the problem, I made one myself, using about an hour of conversation with Gemini GenAI to create and refine code for a simple online app. It does the job I need it to do.
This is the broadcast clock <profjoecain.net/clock>. Version 1.0.
Use it for free.
The app is designed for a 60-minute output cycle. The app allows a user to list programme segments and timings. Colours in the clock can be modified. When finished, it allows users to download the segment list as a *.csv file and to download the clock’s pie chart as a *.jpg. There is no other save or upload feature. (I’m not *that* good with coding.) An example of the output is below.
What this clock lacks is a way to insert segment titles into the clock face. I’ll work on that for version 2.0.

The segment list downloads as a *csv file. The chart below was used to create the clock above.
