## Description

Save the lessons worth keeping. Every one comes in three depths: High School,College, PhD, so you can revisit anything at exactly the level you want.

Most facts go in one ear and out the other. Field Guide is built so they don't.

Each lesson takes two or three minutes and follows a simple loop proven to build memory: you predict an answer first, you get taught one clear idea, then you're quizzed on it. Guessing before you learn is the trick that makes it stick.

Then spaced review brings each lesson back days later, right before you'd forget, so it moves into long-term memory instead of fading by tomorrow.

WHAT'S INSIDE

Hundreds of lessons across science, history, money, health, art, engineering and more
A predict → teach → check loop that's actually fun
Spaced review that schedules itself
A streak to keep you honest
Clean, calm, no-fluff design. No ads, no clutter.
Browse by subject, get a fresh lesson each day, or hit Random and learn something new right now.

Field Guide works fully offline, and new lessons arrive automatically.
