Updated June 2026 · All picks are free to download
Take roll in seconds and spot attendance patterns at a glance — built for teachers, coaches, and instructors who refuse to fight their software before first period.
A live decibel meter for the classroom: set a threshold and let the meter be the bad guy. Pairs with the free web noise meter on this site — in your pocket for the corridor and the gym.
Time stations, races, and group activities with independent stopwatches — including from your wrist with the Apple Watch app. PE departments, this one is yours.
For music lessons: a one-tap metronome with 36 tempo presets and beats from 1/1 to 1/8 — the simplest click in the room, used by tens of thousands of musicians.
Quick grade-point math for advisors, homeroom teachers, and students — semester and cumulative GPA without a spreadsheet.
Before installing anything, the whole classroom toolkit runs free on this site: visual timers for transitions, a team scoreboard, random name picker, group generator, seating chart, teaching clock, times tables, and a noise meter — no accounts, no installs, whiteboard-friendly.
