> Tickario

Tickario is a free time tracker for freelancers and independent professionals. It lets you log billable hours by client and project, set hourly rates, and send clean reports.

It flags overlapping timers for the same client so time isn't billed twice, supports rates per entry, project or client with per-currency totals, and exports reports to PDF or shares them as a link.

Sign-in uses a one-time email link with no password, and the site says data is kept on its own infrastructure and never sold.
