Have you seen a tutorial or community post but can’t find the block mentioned in your project? Or are you just looking to unlock more powerful features and tricks? This guide is for you!
Blocks fall into four main categories: Blocks that you can use right away, blocks that need a component or a data source, blocks that you need to activate, and blocks that need an API key.
1. Blocks You Can Use Right Away

Core blocks, such as Control, Logic, Math, Text, Lists, Color, Device, Objects, Variables, Functions Blocks.
Some blocks like Speech, Sound, Share, Camera, Files, Sign In, Location, Push Notifications, In-App Purchase were components in older Thunkable versions. Now, they’re part of the App Features and can be accessed directly from your project’s Blocks tab.

Some blocks only appear after you add their corresponding components from the Design tab.
Block categories: Canvas and Data Sources
