brb. - A Hallway sign out replacement for Elementary School!

Hey Product Hunt 👋 I'm a teacher (well, I was — also a builder now). brb. is the touchless hall pass kiosk I built for my own classroom because I was so done with the gross unreliable clipboard. The problem: every classroom in America has some version of this — a sign-out clipboard kids pass around, a magnetic chart, a paper log. Kids forget to sign back in. They miss the clipboard entirely. They pass it around with sticky hands. Teachers get interrupted mid-lesson to write a name down. The data is unusable for spotting patterns. There are like 47 hall pass apps and most of them are clipboards-with-extra-steps. What brb. does: 🚻 Mount an iPad / Chromebook / laptop by the door 👋 Students wave at the camera to sign out (no touching anything) 🎯 They pick a reason (bathroom / water / nurse / etc.) with a hand gesture 📸 The kiosk snaps a photo so teachers know who's out 🔄 Easy sign in on return 📊 Teachers see a real dashboard — frequent flyers, average time out, time-of-day patterns A few things that make it different from the other 67 apps: → Truly touchless. Built on MediaPipe hand tracking. Works on any device with a webcam. → Privacy-first architecture. All student data lives on the classroom device. No central database. No student names, photos, or sign-out logs ever leave the iPad. Schools can verify this — there's literally no API endpoint that returns student data. → Anti-spoofing without surveillance. Each student picks a secret cartoon animal at sign-out. They have to match it on return. Prevents kid A from signing in pretending to be kid B, without facial recognition databases or anything creepy. → One teacher, one device, $39.99/year. Or $4.99/mo. Or one-time $199 for the first 100 founding teachers. They will have access for life and access to my other projects launching soon. Schools can buy site licenses (email me). What I'm asking PH for: → Try it free for 14 days, no credit card to start → Tell me what's broken — I'm an teacher building for teachers. → Schools/admins reading: hello@brbkiosk.us for site license pricing Thanks for taking a look 🙏 — Big Brain Labs LLC
