I just completed a holiday project this week to measure the kids screen time using an Arduino device and a web app! I got frustrated trying to get so many parental control apps to play nicely, in the end this seemed like a bolder new approach to the problem.

I blogged about the whole build and coding project [here](https://partridge.works/screenie-christmas-project-2025-26/)

Code for the Arduino and also the web app is Open Sourced [here](https://screenie.org/get-device/selfbuild)

And you can play with it [here](https://www.screenie.org)
