About this app

Who loves whom, who betrayed whom, and which family does everyone belong to? RelationMap turns a cast of characters into a clear map you can read at a glance.

Built for writers, worldbuilders, game masters, fan fiction authors and anyone keeping track of a big story.

HOLD, DRAG, LINK
• Hold an empty spot to add a character, or tap +.
• Hold a character until it lifts, then drop it on another to connect them.
• Drop it on Link to new to create a connected character in one move.
• Name each relationship: rival, mentor, sister, secret alliance. Turn on Mutual when it goes both ways.
• Undo is one tap away.

A FACE FOR EVERYONE
• Add your own picture to any character.
• Characters without a picture get a drawn face. Choose a style per map: initials, sketch, illustrated, hand-drawn, pixel or blobs.

GROUPS AND FACTIONS
• Put characters in groups to colour whole houses, crews or factions.
• Colour relationships so feuds and friendships stand apart.

SHARE AND BACK UP
• Export a map as PNG, JPG or PDF and send it anywhere.
• Save a map as a JSON file to back it up, then import it again from the Maps tab.

PRIVATE BY DEFAULT
• No account and no sign-up.
• Your maps are saved on this device as you edit. We don't upload them.

ONE APP, MANY KINDS OF MAPS
Use it as a character relationship map for your novel, a family tree for a fantasy kingdom, a story planner for the cast of your next book, a worldbuilding chart of rival houses, a D&D campaign map of NPCs and allies, or a quick who's-who diagram while you watch a long TV series or read a manga. Keep track of your OCs and how they know each other.

START FAST
• Open the Project ARIA sample or the British Royal Family template and change it into your own.
• A short tour shows the gestures the first time you open a map.

Works on phones and tablets.
Map characters, families and factions. Hold, drag, drop to link. Works offline.
