Field Guide vs Underfoot

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.

Underfoot is a field guide for anyone who can't walk past a bug without stopping to look. Point a phone at an insect, spider, or under-a-rock critter, and Underfoot tells you what it is — then it becomes a specimen card in your collection, illustrated by hand like something out of an old field notebook. Not a checkbox. Not a badge. A card you're proud of. HOW IT WORKS • Point, identify, collect. Photograph a bug and get an honest identification — and when the app isn't certain, it says so, narrows to the group, and shows you a real reference photo to check against, so you learn instead of just being told. A wrong first guess is never a dead end: you can decline it and search the guide yourself. • Hand-drawn specimen cards. Over 2,000 U.S. insects, spiders, and under-a-rock critters — roly-polies, millipedes, snails, centipedes — each with its own ink-and-watercolor illustration. • Collect anything. Found something rare that isn't a pre-made card? Collect it as a "wild find" and the app draws its card on the spot. • Where to look. Every entry has a plain-language habitat tip, plus real parks and trails near you to go hunt. • In season. See which bugs are out right now in your area, so there's always a reason to go outside. QUIET BY DESIGN Underfoot is a general-audience app operated through a parent. There are no accounts to create, no login, no email, no ads, and no behavioral tracking. A profile is just a nickname and a chosen mark — never a full name, an email, or a photo of your child. The only thing sent off the device is the bug photo itself, sent once to Google's identification service to name the insect — never anything about who took it. Location is coarse and optional, and your exact position is never stored. Browsing your collection works fully offline, and one tap deletes everything. The outdoors is the product. Underfoot is built to be picked up, used for a few minutes, and put back in a pocket — so you get back to turning over rocks. FREE & PRO Collect up to 10 species for free. Underfoot Pro unlocks the entire guide — unlimited collecting — for $2.99/month or $24.99/year. Auto-renewable; cancel anytime in Settings. No weekly billing, no tricks. Restore Purchase is right on the paywall. Made by someone who takes the curiosity seriously.
