About the studio
LearnHubPlay is an independent software studio in Amsterdam. We build small productivity tools and write about the problems they are meant to solve: keeping attention on one task, keeping notes where you will find them again, and building routines that survive a bad week.
Each guide lists its sources at the end. Our editorial policy explains how we research, check, and update them.
