Final Deliverables

Final Builds

PBS will need all source files for the project, as well as up to three final binary files. These files should be delivered to PBS as separate ZIP files. Both the ZIP file and the binary should have the same name as the official name of the app that will be in the App Store. All final builds should be compiled with the most-current Apple SDK and with the distribution certificate supplied by PBS. All apps should be tested on the iPod Touch as well as on the iPhone, using the newest OS available.

  1. A Distribution Build that PBS will upload for Apple technical review and posting in the iTunes Store. This should be compiled with the most recent version of the iPhone SDK at the time of delivery, using the PBS Distribution Certificate and posted to your project site as a ZIP file, with the suffix _dist.
  2. A Release Build that PBS can share with Apple for their editorial review when Apple considers promoting the app. This should be compiled with the most recent version of the iPhone SDK at the time of delivery, using the PBS Distribution Certificate as an Ad Hoc build with the suffix _rel.
  3. A Demo Build (only if requested by PBS) that could be incorporated into either Apple’s standard demo device image for a period of time (generally one calendar quarter). This must have limited content, so please consult with PBS to find the best way to limit the content for the demo build. This build must be compiled with the most recent version of the iPhone SDK at the time of delivery, using PBS Distribution certificate as specified above. Both the ZIP file and the binary should have the same name as the official name of the app that will be in the App Store; primary screens must be modified to indicate that it is a demo version.  Carefully read and follow the “Instructions for Submitting your iPhone/iPod touch Demo Application” found in the Apple Developers Center.

iOS Art Asset Specifications and Guidelines

Artwork serves to draw attention to your app in the store and give users an idea of what your app looks like.  Several pieces of artwork are required to accomplish these roles and each developer requires different criteria.  This section provides all dimensions and criteria for your app artwork.

(warning) Because of all of the different devices to which your artwork can be applied, it is critical that you design your artwork to fit all variations. 

 

We do our best to keep these guidelines up to date, however, we strongly recommend that you reference the specifications for each platform.

Important notes about Art Asset submission

  • If your app is localized into different languages, we would like to collect these assets as well. Please separate those assets and place them into subfolders named for the specific language used.
  • The background image, texture, color or gradient should correspond to the application and complement the Title Treatment. It may include elements of the application itself, but should not be, nor include, screenshots.
  • The title treatment should be easy to read when scaled down to a small size. Please remove all tags or bylines.
  • If you wish to combine your Title Treatment with your Background Art for placement ideas, please make sure that all elements are on separate layers.  

Things to avoid

     (minus) Pixelation, artifacts, high-contrast background art, blurry or hard crops (unless stylistic); keep all talent visible.

     (minus) Imagery depicting sex, violence, gore, drugs, explicit language or hate themes .

     (minus) Any visual representation of iPhone, iPad, iPod, or any other Apple hardware.

Google Play Art Asset Specifications and Guidelines

  • The high resolution and launcher icons should be generated from the same file to create a clear user experience. The recommended way is to start from a large size or vector graphic, and scale down from there. The Android Asset Studio can help create these sizes.
