Austrian schools pioneered a 21-day no-smartphone experiment in 2025. Now it's going international with 2,000+ teachers registered. Scientific monitoring by Anton Proksch Institut and Sigmund Freud University shows students report better sleep, less stress, and improved mental health.
"I slept so long and well today, like I haven't in weeks. I feel physically and mentally better, I have much less stress."
"I definitely noticed that without social media I feel mentally better, because you compare yourself way too much."
"I'm consciously enjoying these last smartphone-free hours. I actually don't want to turn the phone on. Because I've had the most important realization of the whole experiment today: I'm happier without my phone."
