# Tutorial#1: Image Hide-and-Seek

Welcome to our app development tutorial! This guide is tailored for beginners who are just embarking on their exploration of the app development world using a low/no-code approach. Throughout this tutorial, we will be utilising the [MIT App Inventor](https://appinventor.mit.edu/) platform to craft and shape our app.

Download the assets folder from [HERE](https://drive.google.com/drive/folders/1N5u0SnSt5F2cRtbXKLr_QGsSLoXdWgye?usp=drive_link)
{% endhint %}

{% hint style="success" %}
If you are solely interested in building and testing the app, skip ahead to the [Building Your First App](#building-your-first-mobile-app) section. You can download the project [HERE ](https://drive.google.com/file/d/1jNAHLeCw0DCABgpeTJZoDHh6bX-A4g9q/view?usp=sharing)and open it in the MIT App Inventor platform.

### Learning objectives

By the end of this tutorial, you will gain proficiency in:

1. Navigating the MIT App Inventor platform.
2. Designing basic user interfaces.
3. Constructing logical processes based on your designs.
4. Testing and sharing the app through at least two different methods.
