Here are the top six world-building apps for your Android phone.

1. Pocket Campaigns

Pocket Campaigns is useful for both roleplayers and writers, despite its name. You create each world as a “deck” of cards. Each idea is a single card in your deck, and you can link those cards to each other within a deck.

The app provides basic templates and character generators. You can also make your own generators by editing a copy of the basic file. The app is very flexible, so you can make it as detailed or basic as you like.

2. World Scribe

World Scribe uses templates to help guide your ideas from general concepts into concrete world elements. Adding an entry is quick: just name it and select a general content type. After that, you can fill in details as they come to you.

The app lets you cross-reference related ideas. And if you haven’t added the thing you want to link yet, you can add a quick version as a placeholder and fill in details later.

3. Quest Tracker—Campaign Notes

Quest Tracker is super-streamlined world-building apps. It offers three fields for every item: Name, Short Description, and Long Description.

5. Game Master Journal

Game Master Journal starts with five categories for your ideas. You can’t add more, but you can rename them. The defaults cover the basic needs for a campaign setting, but you could rename the first four to “Plot,” “Characters,” “Locations,” and “Organizations” to make it work better for novels.

Within a category, you can filter the entries by various factors. Each category comes with a template to make sure you enter the important information. You can also edit the templates or add new ones.
