ActivityWatch

ActivityWatch is an open-source cross-platform application that tracks how you spend time on your devices, and keeps you in control of your data. Note about accessibility permission: the app allows users to optionally grant the accessibility permission to enable collection of detailed browsing history, by tracking URLs from supported browsers. Please note that ActivityWatch for Android is in an early stage of development, and might have bugs. You can report issues and view the source code on GitHub: https://github.com/ActivityWatch/aw-android
