Let's make your life a bit easier, here's a guide on what creative assets you'll need for submission to the Apple App Store.
App Store Description:
A short description of your app to help engage your future community members and let them know about your app's key features.
The first 255 characters are immediately visible to users before they need to hit the "More" button. If you have information about pricing, this generally goes towards the end.
App Store Keywords:
Help people find your community by using several keyword search terms. You can use up to 70 characters.
App Store Screenshots:
It is so important to give your potential new members a sneak peek of what to expect inside the app using screenshots.
