Harvest + Harvest Reaper
Turn your calendar events into time entries.
Harvest Reaper is a tool that takes your Google Calendar data and automatically generates a list of events for the week, pre-filled with duration and event title. From there, you can use dropdown to select the right projects and tasks. Harvest Reaper learns from past entries, so for recurring events the project and task are already filled in! Once done, hit "Submit to Harvest", and just like that your entire week is completed.
Harvest Reaper is an open source project that you can host in your own server or local environment. Any organization can download it, use it, and add features to it through the GitHub project page.
