# App info

<figure><img src="/files/DCU613zijH1oPFuxVbsI" alt="App Info screen in Twinr Builder. The left sidebar lists App Info, Launch Screen, App Permissions and App Settings. The form shows an App name field labelled max 30 characters and optimal up to 12, an App icon upload accepting JPG, JPEG or PNG at 1024 x 1024, and an Icon background section with Background color selected and a #FFFFFF colour field. A live Android and iOS phone preview appears on the right, with an Update button at the bottom."><figcaption></figcaption></figure>

### App name

This is the name you given while creating a new app. You can update it here if you want.

### App icon

App icon is your brand icon. It will help people identify your application on stores.

* Upload your brand icon. Default logo is provided by Twinr.
* You can see the preview how it will look in Android and iOS mobile devices on the right side.

Note: <mark style="color:red;">You must upload 1024px x 1024px size image. This is required for uploading on the stores.</mark>

### Icon Background

Some Android devices display app icons in different shapes (circle, square, or rounded square), which may leave **white spaces** around the icon.\
To ensure a consistent and clean look, you can set your **icon background** in one of two ways:

1. **Background Color:**
   * Choose a solid color using the color picker or enter a hex color code.
   * Example: `#FFFFFF` for white or your brand color for consistency.
2. **Background Image:**
   * Select this option if you prefer using an image as the background instead of a solid color.

> ⚠️ **Note:** Use a **PNG** icon with transparency for the best results.
