# App Fields
App Fields is where you manage your variables inside the app, just like the **Custom Fields** section in your chatbot.
If you are unable to create app fields directly in other places in the app, create them here.
Click on **New App Field** and give a field name. It's a good practice to leave no space, but use underscores or hyphen to separate words. Pick a variable type. Add default value or description if needed.
Folders can be used to organize variables. Trust me, you will need it when your app goes big. 🧐
