Daily micro-learning
that actually sticks.
We build micro-apps that turn rich subjects into daily rituals that take less than 60 seconds. You learn, discover, or improve a little every day, without overload.
Our philosophy
Micro-learning, not noise
Every app is designed to turn one distracted minute into real progress.
Zero overload
One useful idea at a time. No endless scrolling, no decision fatigue, just the essential.
Useful micro-learning
Each session takes under a minute, but the compounding effect over time meaningfully changes what you retain.
A ritual that lasts
Apps designed to become a simple, satisfying, lasting daily habit, far from doomscrolling.
