Stint is a specialized time tracker and invoicing system for professionals selling their services as blocks of time. Define multiple projects/customers and rates and add time entries quickly either using an automatic timer or manually using efficient gestures. When you are ready, create invoices for partial time spent or charge for time in advance.

The elegant interface allows you to focus on essential functions.

As you enter the time spent on each project, Stint displays how long you've spent and how much is left.

You can invoice selected entries or a specific number of days and round the total automatically. Extra time charged or spent can be kept for future invoices as credits or charges, or discarded. Stint is adapted to various business models.

Stint automatically places its data in iTunes if you need to access it in another software package via a CSV file. Emailing of all the data is also supported.
