The following graphics are required to build your app:
Images must be 24-bit PNG formatted images (not interlaced)
Images should be 72 dpi
Do not use transparency unless noted
iPhone graphics:
Must not have drop shadows, rounded corners or shine/gloss effects.
Apple specifically require:
Icons have 90 degree corners (no rounded corners)
Icons do not include a drop shadow
Icons do not have any shine or gloss (unless no shine or gloss is desired)
Icons do not use alpha transparency
In addition, good guidelines are:
Do not include the app name (product name) in the icon as text (it's always present under the icon)
Ensure art and any text is crisp and legible at all sizes
Shine, gloss and rounded corners on Android:
Apple add these automatically but they are not added for Android versions. These must be added manually by a designer prior to app submission if rounded corners and/or gloss is desired.
One App Icon - this cannot be changed once your app is submitted
Android icon: 512 X 512 pixels
iOS store icon: 1024 X 1024 pixels
Launch images - (splash images) - these cannot be changed once your app is submitted
Google Play Header: 1024 X 500 pixels
iPhone 4: 640 x 960 pixels
iPhone 5: 640 x 1136 pixels
iPhone 6: 1242 x 2208 pixels
iPad portrait: 1536 x 2048
iPad landscape: 2048 x 1536
Apple advise not to use the launch image as an "app entry experience" or "splash image". Their recommendation is the launch image should look like the first screen of the app.
Event Icon - this can be changed once apps are submitted, but we require it to be inserted so that we can take screenshots for the stores.
120 x 120 pixels - PNG
Re use your app icon (same dimensions and should be same image). Used for push notifications/in event feed for producer messages.
If your app is a multi-event app, you can have different event icons for each event. For the app store submission, we only need one event icon to create sample screenshots that make up part of the description of the apps in the store.
Event Poster - this can be changed once apps are submitted, but we require it to be inserted so that we can take screenshots for the stores.
640 x 744 pixels - PNG
Orientation: Portrait
The Poster is the event home screen – the first thing people see when they’ve logged in.
