A list tells you who is in your contacts. A relationship map helps you remember how those people connect.

Perhaps Jordan introduced you to Maya, Maya collaborates with Priya, and Priya belongs to a volunteer group you know. Remembering those links can help you understand a conversation, find shared context, or consider an introduction.

Relationship mapping makes those connections visible. Start with the relationships you know and a question you want the map to answer.

Dextr is our first pick on Apple devices for keeping an introduction connected to the people involved. Record the introducer and meeting context, then use a reminder for the next action.

This guide is published by Dextr. The recommendation reflects the workflow described here.

What is relationship mapping?

Relationship mapping is the process of recording and organizing connections between people or organizations. A simple map represents people as points and their relationships as lines.

For a personal network, you might label a connection Friend, Colleague, Mentor, or Collaborator. A business map might show clients, organizations, and decision-making roles.

Maps serve different purposes. This guide focuses on your personal and professional network, including introductions and shared communities. Large account-planning and stakeholder maps may require different software and information.

A simple relationship map example

Imagine five people:

  • You met Jordan on a previous team.
  • Jordan introduced you to Maya.
  • Maya collaborates with Priya on community workshops.
  • Priya mentors Alex.
  • Alex volunteers with you at the local library.

These are several distinct facts. Jordan's introduction explains how you met Maya. Maya and Priya's collaboration describes their connection. Your shared volunteer work with Alex describes another.

The map can help you recall why a name feels familiar. It may also reveal a route for asking about a potential introduction.

Keep the underlying facts separate. If Priya and Alex are both in a professional association, that alone does not establish that they know each other. Record a connection when you have a basis for it.

Decide what question the map should answer

A map becomes easier to build when you choose a purpose.

For a community event, you might want to remember which volunteers have worked together. For a professional project, you might want to identify people with relevant experience and the contacts who introduced them.

Useful questions include:

  • Who introduced me to this person?
  • Which people have collaborated before?
  • Who belongs to this community?
  • What connections do I already know between these contacts?
  • Who could I ask about a possible introduction?

A map does not tell you whether someone is willing or able to help. You still need to ask.

Build your first map in five steps

1. Choose a small community

Start with a club, project, former workplace, or professional group. Five to ten people is enough to test the approach.

Write down their names and the context you already know. Leave unknown connections blank.

2. Describe your relationship to each person

Choose a useful description of how you know them. Former Colleague, Friend, Mentor, and Collaborator can be enough for a first map.

Keep the description current. If the relationship changes, update it when that helps you understand the connection.

3. Add connections between other people

Record relationships that exist independently of you. Maya collaborates with Priya even if you know each of them through a different setting.

Use consistent labels so the map remains readable. Some connections are symmetrical, such as two colleagues. Others have a direction, such as Mentor and Mentee.

4. Preserve introductions and shared occasions

An introduction and an ongoing relationship can both matter. Keep who introduced you and where you met as context, alongside the current relationship.

For example, someone may introduce two people who later become collaborators. The original introduction is still useful history.

5. Review the map against your question

Look for the person, community, or connection you needed. Add missing context when you learn it. Remove a relationship label that is no longer accurate.

The most useful map is the one you can keep understandable.

Dextr on iPhone: remember the meeting and introducer

Dextr First Met and Introduced By sections on iPhone in dark mode, with the meeting date, venue, notes, and introducer filled in.

Dextr lets you record your relationship to a contact and connections between contacts. Its Social Graph provides a way to explore those recorded relationships.

Begin with How to Connect Relationships in Dextr for the product workflow.

For custom relationship groups and types, the advanced relationship networks guide explains how to organize a community. Creating and managing custom types and groups requires Dextr Pro.

A few distinctions keep the structure useful:

  • Relation to You describes your connection with the person.
  • Relationships between contacts describe how other people know each other.
  • Tags describe overlapping interests, organizations, and communities.
  • Introduced By preserves the person who connected you.

Dextr records one relationship type between a pair of contacts. Choose the most useful description and use tags or journal notes for additional context.

Dark-mode app examples below use fictional demonstration contacts.

On iPhone, First Met and Introduced By preserve the meeting context and the person who connected you.


Dextr on iPad: explore relationship connections

Dextr Social Graph on iPad in landscape and dark mode, with named contacts and relationship groups connected on the map.

On iPad, Social Graph shows relationship connections in a different view. The graph complements the introduction record; it does not establish that two people agreed to an introduction.

Use tags for community membership

Membership and relationship are different pieces of information. Two people can share a club tag without having met.

For example, use a Running Club tag to find members of the same group. Add a Running Partner relationship only when the people actually run together.

This avoids turning every community into a dense set of assumed connections. The tagging guide explains how to organize those overlapping groups.

Turn the map into a thoughtful next action

Suppose your map reminds you that Maya works with someone who has experience organizing workshops. Start by asking Maya whether an introduction would be appropriate.

Give enough context for the other person to decide. Explain why the connection might be relevant, and ask before sharing contact information.

A map can also help you prepare for a gathering. Review names, shared projects, and the introductions you want to remember. Afterward, save any new connections while the details are fresh.

For a broader habit of notes and follow-ups, see professional relationship tracking.

Common questions

Is a contact list a relationship map?

A contact list identifies people. A map adds connections between them. A simple written list of those connections can be a useful first map.

Does a relationship map update itself?

That depends on the tool. Dextr's graph reflects recorded relationships. Review connections as you learn new information.

How much information should I include?

Include enough to answer your purpose. Keep private details out of maps you share, and avoid presenting an assumption as a confirmed relationship.

Do I need a large network?

No. A small community provides a practical starting point. Add people and connections as the map becomes useful.

Choose one circle you know well, record the connections you can describe accurately, and use the map to arrive at your next conversation with better context.
