How to prepare assets for publishing the guest app in the app stores

Overview

To publish hotel apps in the stores, STAY needs you to provide the technical details, graphics, and text descriptions listed below. Providing these assets correctly allows our team to handle the submission smoothly and helps avoid delays during Apple and Google reviews.

Keep in mind that optimizing the store text and images is also key to improving app visibility, making it much easier for guests to find and download.

Before getting started

Before getting started, make sure you have:

  • Coordinated with the STAY Account Manager to organize the handoff of the assets and information explained in this article.
  • Coordinated with your marketing team to gather the required assets and ensure they comply with brand guidelines.
  • Selected the app's languages. Keep in mind that all required texts must be provided translated into those languages.

Note: English is active by default, but you can request the activation of Spanish, Deutsch, French, Italian and many others.

Step-by-step guide

Step 1: Provide app details and branding assets

We need you to specify the following information and assets:

  1. App title: The exact name of the app as it should appear on Google Play and the App Store. It must have a maximum of 30 characters to ensure it fits on a single line across most devices. This field requires translations for each active language.
  2. Desktop app name: The short title that displays directly beneath the application icon on the smartphone home screen. If you don't specify this name, the App title will be used by default.
  3. Typography (Optional): If the brand uses custom fonts and the tier includes it, we need the specific font files for titles, regular text and body strong text.

    Note:     If you do not use customized typography, please indicate that this section is N/A.

  4. Logotype: Send us the official brand logo in a vector format (such as SVG or AI).
  5. Brand color: The exact hexadecimal code of the primary corporate color (e.g., #FFFFFF).
  6. Access to the developer account (optional): To publish the app under a specific developer account, STAY must be granted access.
