For teachers

Tools that give you back the minutes that add up.

Sign-outs, morning meeting, seating charts, PDFs, timers. Small, fast apps for the routines that eat your mornings — built by a working teacher, tested in a real classroom, and simple enough to leave for a sub.

Morning Meeting on the board

Calendar, weather, greeting, jobs, attendance — one screen, no laminated cards.

Morning Meeting

Someone needs the bathroom

They wave at the iPad by the door. The log fills itself in. You keep teaching.

Why teachers keep it

Built around real classrooms, not demos

Ready in minutes

Most apps explain themselves on first open. No training marathon, no admin setup.

Runs on what you have

Chromebooks, iPads, Windows PCs, and the classroom display. Browser-based, no installs.

Student data stays with you

Local-first by default. Rosters and logs live in your browser, not on our servers. No ads, ever.

Works when the Wi-Fi doesn't

Most tools keep working after the first load, even when the building network drops.

Teacher questions
Do my students need accounts?

No. Students never need accounts. Your teacher sign-in covers brb. and any tool that syncs across devices; the simpler tools you just open.

Will it work on my school Chromebooks?

Yes — every app runs in the browser with no installs. Chromebooks, iPads, Windows PCs, and personal devices all work.

What happens to my data if I cancel?

For local-only apps, nothing changes — the data is on your device, not ours. Export anything you want with each app's Save or Export buttons.

Is my school paying, or am I?

Either. Teachers subscribe individually; schools and districts can email for a quote, a PO, a signed DPA, and a W-9.

Try it on tomorrow's routine.

14 days, every teacher tool, no credit card. Keep what saves you time.
