You've built an amazing app and now it's time to show the world! Upload your screenshots for Android and iOS devices at the Google Play and App Store tabs. These are the screenshots that will be displayed in the app stores and on the app site we generate for your app once it has been published.  

Since we can't expect you to own an iPhone 3/4, iPhone 5, iPhone 6(+) and Android, once you've uploaded your favorite screens from the devices you do own, we will take care of the rest. 

Here's how to take and upload screenshots. 

Taking Screenshots

Apple:

1. Open one of the pages of which you'd like to take a screenshot.
2. Press the Home and Power Button at the same time.
3. The screenshot will be saved to the phone's Photos. 
4. E-mail or transfer the screenshots to your computer. 

Android:

1. Open one of the pages of which you'd like to take a screenshot.
2. Press the Volume Down and Power Buttons at the same time, hold them for a second, and your phone will take a screenshot.
