# Blocks

An app is simply a sequence of events.

The best apps define an elegant sequence of events that happen without the user even noticing. A great sign in flow for example can happen in seconds but the logic and sequence behind them is a work of art that has been iterated on many times (often using Thunkable's [Live Testing](/snap-to-place/get-started/live-test.md) app).

This is where Thunkable Blocks come in.

Thunkable Blocks are the building blocks of a great experience for your app users. Every component has its own set of blocks to start or trigger an event and set and change properties.

They can be connected to a commonly used set of blocks that range from opening screens, setting up logic, reformatting data or simplifying code.
