Screen Time Alerts from Activity Watch

Introduction

Activity Watch¹ is a cross-platform open-source time-tracking tool that helps us to track time spent on applications and websites.

At the moment, Activity Watch doesn’t have any feature to show screen time alerts. In this post, we will see how to show screen time alerts using Activity Watch.

Python Script

Activity Watch provides an API to interact with the Activity Watch server. We can use the API to get the screen time data and show alerts.

This script² will show the screen time alerts using the Activity Watch API. We can run this script using the below command.

$ python screen_time_alerts.py
$ python screen_time_alerts.py
$ python screen_time_alerts.py

Enter fullscreen mode Exit fullscreen mode

We can set up a cron job to run this script every hour to show screen time alerts.

$ crontab -e
0 * * * * python screen_time_alerts.py
$ crontab -e
0 * * * * python screen_time_alerts.py
$ crontab -e
0 * * * * python screen_time_alerts.py

Enter fullscreen mode Exit fullscreen mode

We can also modify the script to show alerts only when the screen time exceeds a certain limit.

Conclusion

Since Actvity Watch is open-source and provides an API, we can extend its functionality to show screen time alerts. We can also use the API to create custom reports and dashboards.
