Chrome: Browser extension Chrome Time Track is a simple tool to measure the amount of time it takes to complete a task or milestone from inside Google Chrome.
Chrome Time Track is a great, no-frills solution to keep a running list of how long your to-dos or projects are taking you. It lets you set up a task, then let the timer run in the background. You can quickly check in to see if you're running on time, or if the task is taking you longer than expected. Chrome Time Track also lets you add multiple tasks as you receive them and use the extension's simple interface to start and stop tasks at will. Additionally, Time Track keeps your previous entries until you delete them so you can quickly cross compare similar tasks to see if you're staying on focus and improving over time.
