KaiStore

About

KaiStore is a service channel to showcase your product and allow users to install an app on their phones.

This guide serves as a resource for you and makes sure your app icon, app name, description, and marketing banner are ready for your product page.

App name

An app name is a name for your product. It plays a crucial role in how users discover it on the KaiStore. Choose a simple, memorable name that is easy to spell and hints at what your app does. Avoid names that use generic terms or are too similar to existing app names.

An app name should not be longer than 20 characters.

Subtitle

Your app’s subtitle appears below your app name throughout the KaiStore. A subtitle is a short and striking or memorable message, and is intended to summarize your app in a concise phrase. A compelling subtitle can encourage product page views and installs.

The maximum length of a subtitle is 40 characters.

Icon

The app icon (aka. Launcher icon) is the first visual expression of the app, as it directly and effectively communicates the main feature and purpose with the user. Unified graphic elements allow you to create simple, intuitive, and consistent icons that reflect product characteristics and quality. These elements also ensure your app stands out from other ones.

To ensure the icon is legible in all sizes, avoid adding unnecessary visual details.

For more details, please go to Launcher Icon

Marketing banner

Your marketing banner is a background image that appears behind the icon, app name, and subtitle. It helps communicate your app’s feature and purpose. Using an attractive image can encourage product page views and attract user attention. The image should be simple and subtle. Remove unnecessary visual details to ensure your icon, app name, and subtitle are legible.

Description

Provide a succinct description that highlights the features and functionality of your app on the Product page. The ideal description is a concise, informative paragraph that introduces your app in a few sentences. Such a description will maximize user engagement.

Don’t add unnecessary keywords to your description in an attempt to improve search results. Also avoid including specific prices in your app description. Pricing is already shown on the product page, and references within the description may not be accurate in all countries and territories.

Category

You can assign one category to your app so that users can find it while browsing the KaiStore. The category you select is particularly important for your app’s discoverability on the KaiStore. This will be the category in which the app appears when users browse the KaiStore. Be sure to select a proper category from the list below that best describes the primary function of your app.
