brb.
Available now
The touchless hall-pass kiosk. Mount an iPad by your door; kids wave to sign out and wave again to sign in. You stop writing down "Maya · bathroom · 10:47" mid-lesson.
Touchless sign-out by hand gesture, or tap mode
Live face cards show who is currently out
Dashboard and CSV export catch the frequent flyers
Master Scheduler is licensed separately for schools — it is not part of the teacher subscription. Walkthrough is a free preview while it matures.
Master Scheduler
School license
Draft your specials & common-prep rotation without living in a spreadsheet — per-grade preps, lunch placement, and specialist double-bookings flagged in plain English.
Deterministic scheduler — same setup, same schedule
Take timestamped, low-inference observation notes with quick-stamp buttons, then leave with a glow / grow / next-step wrap-up and a Word or PDF export ready for the post-conference.
Quick-stamp buttons — customizable focus areas
Wrap-up summary + Word / PDF / CSV export
Local-first — notes never leave your device unless you ask for the optional AI summary
Designed, tested, and fixed by a working teacher — every app starts as a real classroom problem.
Privacy-conscious
No ads and no selling student data. Local-first where possible — most tools keep data in your browser.
Works on school devices
Chromebooks, iPads, Windows PCs, and classroom displays. Browser-based, no installs.
Simple to adopt
Most apps explain themselves on first open — no training marathon, simple enough to leave for a sub.

From the founder
Built by a working teacher
Big Brain Labs began because everyday classroom tools were too complicated, too expensive, or designed by people far removed from classrooms. Each app starts with a real school problem and is refined through actual classroom use.
“I polish every tool until I'm proud to use it with my own students. Then, and only then, does it go on the internet.”— Mr. B, K-12 teacher & founder
Big Brain Labs is a growing toolkit of simple classroom apps built by a working teacher. The lead product is brb. — a bathroom and hallway sign-out kiosk. One All-Access subscription unlocks brb. and every teacher tool, with new tools included automatically.
What does the subscription include?
One All-Access subscription ($4.99/month or $39.99/year) unlocks brb. and every Big Brain Labs teacher tool, with new tools added automatically. Cancel anytime. Master Scheduler (for school leaders) is sold separately, and PDF Lab is free for everyone.
Do students need accounts?
Most tools work without an account. A Big Brain Labs account is used for the brb. kiosk and any tools that need syncing across devices. Students never need accounts.
Does it work on Chromebooks?
Yes — every app runs in the browser. No installs. Works on Chromebooks, iPads, school PCs, and personal devices.
How is student data handled?
Designed to support FERPA, COPPA, and NY Ed Law 2-d compliance. Local-first by default — student data lives in the teacher's browser unless a feature explicitly needs cloud sync. No ads. No selling student data. A signed Data Privacy Agreement is available on request for districts.
Can schools purchase licenses?
Yes. Schools and districts can request a quote by emailing [email protected]. We support POs, signed DPAs, and W-9 requests.
