About INTERVAL

What Is INTERVAL

INTERVAL is not a messaging app. It is a human radio signal network that enables presence-based signaling without engagement pressure, reply expectations, or visibility demands. Some signals do not need replies.

Why “INTERVAL”?

Morse code lives in the spaces between — the intervals between dots and dashes, between letters and words, between sound and silence. Operators learn to feel these gaps as meaning. INTERVAL is named for that space where communication actually happens.

The Network

Callsigns

Every operator claims a unique callsign — a NATO prefix and 3-digit number. This is your identity on the network.

Channels

Operators communicate through channels — private, group, or public. Signals are exchanged in real time.

Off-Grid

A spatial awareness view that shows nearby signal activity, presence pulses, and network events — without revealing identities or locations.

Bulletins

Organizations issue one-way transmissions during incidents. No comments, no reactions, no algorithm. A single authoritative source.

Design Philosophy

  • Metaphor: Radio fields, not chat systems
  • Operators represented as circles, signal range as rings
  • Fading pulses for transmissions
  • Signals fade, never stack
  • Silence has visual weight

The Radio Rules

  1. Presence is not visibility.
  2. Silence is not absence.
  3. Listening requires no reply.
  4. Range is meaning.
  5. Signals are not content.
  6. Urgency is encoded, not performed.
  7. No one owes attention.

INTERVAL preserves signal by refusing noise.
