runTimers is a free Chrome extension developed by jashua212. It falls under the category of Browsers and is classified as an Add-ons & Tools subcategory. This program allows users to run multiple timers in a single browser tab, making it convenient for organizing and tracking time.

With runTimers, users can create both progress timers and countdown timers. Countdown timers can be set based on either their durations or specific end times. Additionally, users have the option to add a countdown timer to their Google Calendar by simply clicking on the timer's end time button, which appears in either the Post time or Remaining time column.

One notable feature of runTimers is that all timer data is stored locally in the browser's local storage, ensuring privacy and security. The extension requires permission to access the user's "tabs" to prevent multiple runTimers tabs from opening.

Users can also format a timer's description by selecting the text and using keyboard shortcuts like Ctrl+B, Ctrl+I, or Ctrl+U. By default, runTimers will play a sound and display a desktop notification when a countdown timer ends, providing a convenient way to stay on top of time-sensitive tasks. These notifications will remain open until clicked on.

Furthermore, runTimers offers a Targeting tool, which allows users to create countdown timers based on the projected duration needed to reach a target level. This feature takes into account a constant hourly earn/growth rate and deducts any current level.

Overall, runTimers is a useful Chrome extension that simplifies time management by enabling users to run multiple timers in a single browser tab. Its intuitive interface and various features make it a valuable tool for individuals looking to stay organized and efficient in their daily tasks.
