The thread
between you is alive.

Tether is a two-person app for couples living apart. Instead of more chat, it gives each pair a slow, ritual-based emotional language — daily pulses, memory beads, delayed whispers, and a shared Starling that grows from showing up.

What it is

Not chat. Not a calendar.
The relationship itself, as an object.

Long distance breaks because the relationship stops being visible. Tether makes it visible — a single shared thread, with rituals that survive the days neither of you feels like talking.

◉

The Thread

A live red-and-gold thread on a 3D globe between your two cities. Five visual states — glowing, steady, stretched, frayed, knotted — that reflect the relationship right now.

◌

Daily Pulse

A long-press inside a shared window. They feel it on the other side. Shared streaks, not personal streaks.

●

Memory Beads

Photo, voice, text, or milestone — strung along the thread. A timeline that belongs to both of you.

✉

Whispers & Time Capsules

Messages that unlock on a date, a place, an event, or after the Nth pulse. Slow letters for the long game.

☾

Same Sky

What you both see right now — moon phase, weather, sunrise / sunset. A small daily proof you share a sky.

✦

Your Starling

A shared mascot, born at a 30-day streak. Five evolution stages from Spark to Nova. Grows when you both show up.

⚘

Conflict & Repair

A "we need to talk" tag, a Knot marker, two-step repair prompts, and an "I need space" cooldown. Built so fights don't disappear into chat.

⇆

Reunion mode

Distance ring, countdown, hype mode, plan-together checklist, and a quiet after-meet retrospective.
