A public explainer — no account needed
One honest answer, for the whole world. Built by one builder — Steve Estrada — with his brothers in mind, for anyone who wants their software to tell them the truth.
The short answer
The Human Brain App is one giant, growing platform where a single builder has been turning his ideas into working software — neuroscience-inspired brain labs, honest research tools, playable games, a 3D trade school, a solar company, a coding school, free public utilities, and more — all held to one rule that gives the whole project its spine: no fibs. Nothing pretends to be more than it is. Not the science, not the games, not the numbers on this page.
These are not marketing numbers. They were counted directly from the codebase on September 11, 2026 — files and routes, one by one. A living app changes daily, so treat them as a snapshot, not a promise.

The one rule
Grade every claim. Research pages cite primary sources. Every lab explains exactly what it measures and what it doesn't. Where the builder's own theory of everything is graded, two of its claims are marked "not supported by science" — by his own app, and he kept both verdicts.
Label everything invented. Games are games. Ads are staged comedy. AI art is AI art. Procedural butterflies are "set dressing, not simulated life" — stated in plain words on the same screen.
Give the receipts. Compression labs report real measured bytes. Citation labs link to the primary sources. The oldest surviving answer to "where do we come from?" — the Rig Veda's "Who really knows?" — is quoted on this app's own origin page as the spiritual ancestor of its honesty rule.
Everything on the platform falls into one of three honest buckets — and the app says which.
Computed, measured, or cited — and checkable by you.
Honest limit: 'measured' means measured in your browser or from cited sources — the app never overstates what a measurement covers.
Made up, labeled, and proud of it.
Honest limit: 'invented' isn't a criticism — it's the label. The fun is real; the claims are labeled before they're made.
Beauty and atmosphere, honestly named.
Honest limit: the app tells you, on the same screen, that the jellyfish don't think and the wind isn't weather. That's the rule.
Eight neighborhoods of one platform. Every card links somewhere real.
Self-experiment labs for attention, memory, sleep, decision-making, and more — browser-based drills with honest labels separating them from clinical instruments, so you can measure yourself without a lab coat.

→ See the theory, gradedDozens of playable games — retro arcades, marble runs, Kelproot's genomic forest, 3D towns to walk — each one teaching something real through play, each one honest about what's simulated.
→ Browse the gamesA 3D town with a real electrical curriculum inside — NEC drills, load calculations, quizzes — built as a free trade school for anyone who wants to learn a trade.
→ Visit the schoolA working e-commerce operation — inventory, eBay sync, draft listings, cycle counts, real fee and margin math — running the actual marble and mug business.
→ See the inventory systemA modern solar energy venture with materials-science research, grid simulations, and payback math — grounded in cited research, labeled where projected.
→ Visit the solar companyFree browser tools and games published outside the paywall — no account, no uploads, no tracking — from photo compression to CSV comparison to a kids' learning lab.
→ Open the free shelfA no-fibs coding school, a victims' outreach resource page built to help without tracking, and the honesty labs that grade the rest of the app — including its own builder.
→ Visit the coding schoolA project that lists its own flaws on its front-door explainer is making a promise: the flaws are on the record, and so is the work to fix them.
It's one builder's answer to a question most software never asks out loud: what if everything you made told the truth about itself? Hundreds of pages, labs, games, and tools later — every claim graded, every invention labeled, every flaw listed — the answer keeps looking better. Come take anything you need from it. It's free where it can be, honest where it can't be anything else.
