🔔 Classroom Bell
A free web-based classroom bell app. Put it on your classroom TV or interactive whiteboard and it rings for class start, breaks, lunch and dismissal on your schedule, then announces what comes next out loud. It stays quiet on school holidays and vacations.
⏱ Class Timer
A class timer that shows group work time in big numbers. Use a step timer that chains activities (3 minutes of solo thinking → 7 minutes of group discussion), a stopwatch with laps, and an exam mode that shows the time left — all free.
🪑 Seating Chart
A free seating chart maker: enter student names, set the rows and columns, and it shuffles seats at random and shows a big seating chart. Supports seat partners, avoiding last time's seats, and a teacher's-view chart.
🎲 Random Name Picker & Groups
Free classroom tools in one place: a random name picker, group maker, group role cards, spinner wheel and a presentation queue. You can also leave out students already picked and count how often each student has presented.
🍱 School Lunch Menu
Pick your school and today's lunch menu appears on the classroom screen around lunchtime, using public NEIS data (for schools in Korea). This free tool also shows student allergy alerts and this week's menu.
🚦 Noise Meter
A free classroom noise meter that measures sound levels with the microphone and shows them as a green, yellow or red traffic light. It only measures loudness — nothing is recorded or sent anywhere.
✏️ Whiteboard, QR & Polls
Free tools that work right on your interactive whiteboard or classroom TV: drawing (pen, highlighter, eraser), big QR codes for survey links, yes/no and multiple-choice polls, on-screen sticky notes, and an attention screen.
🌅 Morning Meeting & Class Notes
A morning meeting screen that gathers the weather, schedule, lunch menu, birthdays and countdowns before first period; class notes that show tomorrow's schedule, supplies and homework in big text; a classroom jobs rotation; and a school calendar — all free.
