Here’s a brief checklist of things to make sure you have when submitting your app to the Apple App Store! For whatever reason, Apple almost always uses an iPad to test applications (yes, even if its an iPhone app). So make sure that your app functions fine on a 4 inch screen

• App Store Screenshot Sizes:

Note: When taking screenshots, make sure you are using a none iPhone X screenshot (unless the screenshot is specifically for the iPhone X)

Mandatory Sizes:

1. 5.5 Inches Screen Size –> Either 1242px x 2208px (Portrait) or 2208px x 1242px (Landscape)
2. 12.9 Inches (if your app is available for iPads) –> 2048px x 2732px (Portrait) or 2732px x 2048px (Landscape)
3. 5.8 Inches (Optional, but good if your app displays differently for the iPhone X) –> 1125px x 2436px (Portrait) or 2436px x 1125px (Landscape)
