Cognita: Learn Psychology

A four-year psychology course that shows its evidence, including the studies that failed to replicate.

A four-year psychology curriculum, offline, with no account and no ads. Every claim cited.

Cognita covers what an introductory sequence and the first two years of a degree teach: research methods and statistics first, then biological psychology, then learning, memory and cognition, then development, personality, social psychology and clinical practice.

WHAT IS INSIDE 100 lessons across four years, each 15 to 25 minutes, with on-device narration 60 researcher profiles, from Wundt and James to Kahneman and Loftus 743 glossary terms, cross-linked to the lessons that use them 20 quizzes with worked explanations for every answer 18 landmark studies reconstructed: Milgram, the Stanford prison experiment, Little Albert, Robbers Cave Spaced repetition that schedules the terms you keep forgetting Bookmarks and notes on any lesson, profile or term Three Home Screen widgets: a quote, a term and a figure, each changing daily

HOW IT TEACHES The course teaches the evidence rather than the vocabulary list. Where a famous result failed to replicate, the lesson says so and gives the numbers: ego depletion, social priming, the tapes from the Stanford prison experiment. Where the field is genuinely unsettled, you get the competing positions and who holds them.

Every effect size, sample size and date is stated, because a claim about behaviour that carries no number cannot be checked.

FREE AND PAID The first ten lessons are free. One purchase of $9.99 unlocks the remaining 90 and everything else, permanently. There is no subscription, there are no ads, and there is no account to create. Family Sharing is supported.

EVERY CLAIM IS SOURCED Each lesson ends with its primary sources and further reading. Every glossary term, researcher profile and classic study shows the published work behind it, and the full bibliography is one tap away in the Library. None of the sources are behind the unlock.

OFFLINE BY DESIGN The app makes no network connections of its own. Every lesson, profile, glossary entry, quiz and case study is bundled in the download, so the whole course works in airplane mode. Nothing you read or write here leaves your device. Tapping a citation is the one exception: that opens the reference in your browser.
