How it works

  1. 1

    Listen

    The phone's microphone hears the room.

  2. 2

    Measure

    A live meter shows how loud it is.

  3. 3

    Too loud?

    If it stays above the limit, it counts.

  4. 4

    Photo

    A picture is saved as evidence.

  5. 5

    Alert

    The teacher is notified and it is logged.

What you get

  • Live noise meter

    Animated gauge in green, yellow and red.

  • Automatic photo

    Captured only when the room is too loud.

  • Teacher alerts

    Notification with date, time and class.

  • Alert history

    See every alert, with charts and exports.

  • Works offline

    No internet needed; syncs later.

  • Teacher settings

    Teachers choose the limit and timing, behind a PIN.

Privacy for learners

Calm Class never records or stores sound; it only measures the level. A photo is taken only when the room is too loud, is stored encrypted, and is deleted automatically after 30 days.
