Puncto Timer is a Chrome extension designed for precise measurement of elapsed time between events on web pages. It allows users to start a timer by right-clicking any element on the page, with options for instant start or auto-stop based on specific text appearing in the DOM. The timer runs as a floating overlay and can be manually stopped as well. This tool is particularly useful for performance testing, QA processes, and any scenario where time tracking is essential.

With its straightforward functionality, Puncto Timer serves various use cases such as measuring login, checkout, and API response times, as well as benchmarking reaction times. The extension prioritizes user privacy, collecting no personal data and only requiring basic permissions for context menus and storage. This makes it a reliable choice for professionals seeking an efficient tool to enhance their workflow.
