Timy

Timy is an easy-to-use desktop application to complete your timesheet. It uses the Basecamp API to exchange data.

Basecamp is a well-known web-based project management tool.
Timy is great for freelancers, small businesses and professional teams who are using Basecamp and need to track time on a daily, weekly, or monthly basis.

Timy does not work as a standalone application. It was built to make time tracking easier in Basecamp. The app works on iPhone, Android, Windows, Mac and some Linux distributions such as Ubuntu.
