Loneliness is one of the most common struggles there is. Tether is built to help you overcome it, one small step at a time.

Loneliness is workable

It's a gap you can close.

Loneliness is the distance between the connection you have and the connection you want. That gap is real, it's nothing to be ashamed of, and it responds to the right kind of attention.

A

It's common

Feeling disconnected isn't rare or shameful. It's one of the most widely shared human experiences, and naming it is the first move toward changing it.

B

It's understood

Decades of research explain why loneliness hurts, why it can become self-reinforcing, and, crucially, which actions reliably loosen its grip.

C

It's changeable

Small, repeated steps compound. Tether breaks the science into actions small enough to actually do, on the days you have the least to give.

The framework & the course

Six guidelines, six modules

The app is built on the Public Health Guidelines for Social Connection, six evidence-based guidelines developed through an international expert process. Each one becomes a module of the course. After a short orientation, work through them in order or jump to the one that fits where you're stuck.

Module 1 · Guideline 1

Make Connection a Priority

Treat connection like sleep, food, or exercise: an ongoing investment, not an afterthought. Why it matters for your health and mood, how much you need, your social style, and your first goal.

Module 2 · Guideline 2

Cultivate Social Confidence

Build the skills and self-trust that make connection easier. CBT-based tools for social anxiety: spotting thinking traps, testing anxious thoughts, calming your body, and facing what you avoid.

Module 3 · Guideline 3

Build a Varied Network

Acquaintances, friends, and intimates each matter. Map who is already around you, strengthen the groups and identities that anchor you, and find your next group.

Module 4 · Guideline 4

Invest in Enough Connection

Daily contact and quality both count. Practise reaching out, acts of kindness, the acting-extraverted experiment, and a daily connection system that fits a full life.

Module 5 · Guideline 5

Maintain & Deepen Relationships

The bonds you already have are the highest-yield place to invest, and the easiest to neglect. How friendships unfold, active listening, going deeper, and disagreeing without damage.

Module 6 · Guideline 6

Face-to-Face & Technology

Embodied presence does things screens cannot. Third places, talking to strangers, and using technology as a bridge to connection rather than a substitute for it.

Five optional Explore modules go deeper: Steady Self, Conversation Craft, Choosing Your People, Start Your Own Group, and Connection Against the Odds. Read the full guidelines at socialconnectionguidelines.org.

What's inside the app

The app doesn't end when the lesson does

Lessons hand you practical tools, and the rest of the app helps you use them, so insight turns into something you actually do this week.

One short lesson a day, taught as a conversation with Robin, your guide. Around 5 to 15 minutes each.

My People network map

Map your relationships in circles of closeness, log the contact you have, and link your goals to specific people.

Tick off small connection actions each day. Streaks build, and the app celebrates milestones with you.
