Minuut.io is a free time-tracking tool online that allows you to set up timers to track time you spend on any tasks. It is suitable for personal time tracking, freelancing and free-form billing when you just want your timers and no extraneous features. The service requires no registration to use and your timers are still both private and accessible anywhere as they are identified by a unique address. Because there is no registration and no projects or settings to configure, you can get started in seconds.
