RescueTime is a web-based time management tool (currently in public beta). We offer:

• The ability to see exactly how you spend your time. No data entry, no effort—Your time gets tracked down to the second without you having to actively track it.
• Instant and easy time-management analytics. Instantly know how much time you’re spending on a particular app (like “Microsoft Word”), site (like “Google.com”) or a category (like “Communication”).
• The ability to set time management goals (daily or weekly) and receive notification when you meet (or fail to meet) your goals (coming soon!)
• Tools to see how you compare to other people in your industry (coming soon!)
