Track your billable time!
Rate Clock is a free, ad-free tool that allows you to set a billable rate, and like a stopwatch, track your time and billable amount. It also has a rate calculator, to calculate the billable time for a specified date and time range. Simple yet useful, you'll be able to track exactly the time you have spent performing a task or in a conversation!
Please note, this version is simple a rate clock. It does not provide the ability to save or share billing history, or export into any other format. All information is displayed on screen for immediate use.
