brb. is the simple, touchless way for students to sign in and out of your room. They tap to pick a reason, and you get a clear log of who left, when, and why. Less chaos, more learning.
Wooden passes. Lanyards. Sign-out sheets passed around the room. The same pen and clipboard touched by every kid, every period, every day. You know exactly which clipboard we mean.
One shared pen, one clipboard, one wooden pass — touched by every student, every period, every day. Cold and flu season makes that math worse. Most teachers stopped thinking about it years ago.
Sign-out sheets get scribbled on, ripped, lost. Students forget to come back. The clipboard becomes illegible by Wednesday. There's no real record of who's where, when — just a vague memory at the end of the day.
Students leave the room and you have nothing to show for it. If something happens in the hallway, "I think Maya left around 10:15" isn't an answer. You deserve a record. So do they.
brb. is cleaner, faster, and accountable — without making a single thing harder for you.
Set brb. up on an iPad or laptop near the door. Open the page in any browser. That's the whole installation.
Find your face in the class roster on the kiosk and give it a tap. Big buttons, kid-sized targets — younger students don't need help.
Bathroom, nurse, office, water — one more tap and you're out. Teachers choose which destinations show, so the list stays short.
When you're back, tap your name again. The teacher's log updates instantly — out time, in time, where you went. The clipboard is dead.
brb. runs in any modern web browser — no app store, no installation. Set it up on whatever you already have at the door.
Most teachers' favorite. Stand one up near the door — Safari just works.
School-issued Chromebooks already on the cart. Chrome browser, no install.
Mac, Windows — any laptop with a browser. Open the page and you're set.
A teacher computer at the door works just as well. Any modern browser.
Built for the way teachers actually need to track who's out — quick, glanceable, hands-free.
MediaPipe hand tracking lets students sign out without touching the device. Tap or click works too — it's just options, not requirements. No shared touchscreen to clean, no lost styluses, nothing to pass between 30 kids.
Every sign-out captures a quick photo and a timestamp, indexed by reason. Open the log to see who's out, who returned, and when — no clipboard, no detective work.
Every sign-out captures a time-stamped photo. Searchable gallery. 30-day auto-deletion built in.
Kiosk locks after your chosen idle time, when you switch tabs, or at the end of the school day. Student photos stay behind a password.
Switch periods with a tap, or set a schedule and let brb. switch automatically. Separate rosters, galleries, and pass logs per class.
Sign two students out as a pair — both faces appear in the queue, signed in together.
A separate substitute password gives subs the action buttons without exposing your settings or gallery.
Mark students whose frequent trips shouldn't flag — invisible to other students. Discreet by design.
See who's leaving the most. Export pass records as CSV for admin reports, parent conferences, or your own peace of mind.
Most ed-tech tools talk about privacy. brb. is built around it. Student names, photos, and pass records live entirely in your browser's local storage — on the device running brb. They never reach our servers, never sync to the cloud, never become a dataset somewhere.
