TimeCoder is a stopwatch with basic logging functionality. When you press the space bar or the "Log Current Timestamp" button, the app will append the currently elapsed time to a list of timestamps directly below the stopwatch.
An example use case: When I am recording video, I use TimeCoder to mark points in the recording that I want to refer to during editing and post-production.
Please note: This app does not currently have data persistence, so if you refresh the tab, you will lose the stopwatch time and your list of timestamps. When I need to save a list of timestamps for later reference, I usually just take a screenshot of the list.
If you're not interested in the code and just want to use the app, head here. You can also download a pre-built version of the app from the Releases tab to use locally. There will also be a pre-built version available through itch.io in the future.
