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.
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.
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.
A long-press inside a shared window. They feel it on the other side. Shared streaks, not personal streaks.
Photo, voice, text, or milestone — strung along the thread. A timeline that belongs to both of you.
Messages that unlock on a date, a place, an event, or after the Nth pulse. Slow letters for the long game.
What you both see right now — moon phase, weather, sunrise / sunset. A small daily proof you share a sky.
A shared mascot, born at a 30-day streak. Five evolution stages from Spark to Nova. Grows when you both show up.
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.
Distance ring, countdown, hype mode, plan-together checklist, and a quiet after-meet retrospective.
If either partner has Premium, both partners get Premium — no overlap billing. Subscriptions auto-renew via the App Store / Google Play. Pricing may vary by region.
Plum and ruby on a night-sky canvas. No notifications you didn't ask for, no public feeds, no public profiles. Two people. One thread.
The 24-block design system that shapes every Tether screen.
