1. About app theme

An app theme is a collection of color schemes and other design attributes that create a sense of visual consistency throughout the entire app.

With Alphonso, you can configure the following components:
  1. Logo
  2. Colors
  3. Corner style
  4. Product image ratio

2. How to create the app theme? 

To create your unique app theme, simply follow these steps:
Step 1: Go to Design > Theme.

Step 2: Customize the components.
  1. Logo: Upload your logo to display in the middle of the home screen’s header. For optimal results, the logo should be a PNG or JPG image file with an optimal size of 150 px x 50 px.
  1. Colors
    1. Primary color: Set the primary color for buttons and product badges.
    2. Secondary color: Define the color used for notification badges.
    3. Header background: Choose the background color for the app header, with header text in contrasting black or white. 
    4. Bottom tab background: Choose the background color for the bottom tab. 
    5. Bottom tab icon active: Set the color for the icon and label in the active bottom tab.
    6. Bottom tab icon inactive: Set the color for the icons and labels when they are inactive.


  1. Corner style: Search bar, buttons, form fields, and other elements in the app can come in rounded-corner or sharp-corner. Select the style you prefer for your app.
  1. Product image ratio: Select one of the three aspect ratios available for your product images, namely Square 1:1, Rectangle 2:3, or Rectangle 3:4. 
Tip: Select a proper image ratio based on the majority of your product images. For images with different ratios, they can fit into the designated container without being cropped. However, it's advisable to replace them with images having the same ratio as the others to enhance a sense of harmony and unity throughout your design.


Step 3: To finish, click Save draft in the bottom right corner. 
Please note that saving a draft affects only the design page, allowing you to make further changes. To make the current design available to all mobile users, click Publish to Mobile
