Details

This is a very simple launch/refresh timestamp recorder web app implemented as one single HTML file with JavaScript code in it. It will automatically create a timestamp (with no text associated with it) when the app is launched. The app will display a hardcoded maximum number of previous timestamps. It also has a button to clear the timestamps. I have added showing of duration between current timestamp and immediately previous timestamp.  

This web app is useful on PC to quickly and easily record timestamps and also to capture typically small break duration or even small task duration. To use it, just open the HTML file in a browser (I have used it and tested it mainly, if not only, on Chrome). To add a timestamp on the open HTML page, simply refresh the page. I usually keep the HTML file open in a browser tab to make it easy to quickly access it and record a timestamp by clicking on refresh button.

For Android mobile, I have an Android app (written in Kotlin): Very Simple Launch and One-Touch-Add Timestamp Recorder Android App, https://raviswdev.blogspot.com/2025/02/very-simple-one-touch-timestamp-on.html . On Android mobile, the Android app is much faster than this repo's web app as first a browser app has to be loaded and then this web app has to run within the browser. On mobile, if the browser app is already open, this web app is also quite fast.  

For the HTML page code and more info., please visit the app's GitHub repo:  https://github.com/ravisiyer/LaunchTimestampWebApp .
