About ActivityWatch

ActivityWatch is a time tracking app that automatically records which applications and window titles are in use on a device. With browser extensions for Chrome or Firefox, it can also track the active tab, and with editor watchers it can track time spent writing code. Users can group usage into categories and use the results to follow time spent on projects, screen time, and work hours. The homepage says the app stores its data on the user's device and does not upload it to the cloud. It also describes the software as open-source, licensed under MPL-2.0.

Several limits are stated on the homepage. Synchronization between devices is listed as still in development. Browser tab tracking is described only for Chrome and Firefox. macOS version and architecture support varies by release. The homepage mentions optional ActivityWatch Pro subscriptions starting at $5/month, but it does not say which features those plans include. Setup involves installing the application, confirming that it is running in the system tray, and opening the interface at localhost:5600 in a browser.
