Attensia: Cognitive games based on real psychology tests

Hey Product Hunt! I'm Anshul, founder of Antilver Systems, and I've been building Attensia. The idea behind Attensia came from a simple observation: many brain-training apps offer entertaining puzzles but provide little clarity about what cognitive abilities their games actually measure. I wanted to build something different — an app where the games are based on established cognitive psychology tasks, rather than invented minigames wrapped in scientific-sounding claims. Attensia currently includes 62 games covering attention, working memory, processing speed, cognitive flexibility, spatial reasoning and logical reasoning. Some of the tests include Stroop, N-Back, Flanker, Simon, Trail Making and several other established paradigms. A few things we deliberately decided: • No advertisements. • No subscriptions or recurring payments. • Start free with three unlocked games in your tier. • One-time purchase to unlock everything, including future additions. • No exaggerated promises about improving IQ or transforming everyday cognitive abilities. We're still improving the experience and would genuinely appreciate feedback on the games, interface, difficulty progression and overall experience. If you've tried cognitive tests before, I'd particularly love to hear which ones you'd like to see implemented next! Thanks for checking out Attensia. — Anshul Founder, Antilver Systems Pvt. Ltd.
