A single event lite app contains the content of your event and should reflect the event branding through the artwork and colours. Following our guidelines to create your artwork, ensures that images in your app will appear optimally across different devices and screen sizes.

In the table below you will find the required dimensions for the artwork. For all images you can use either PNG or JPG, unless specified otherwise.

IMPORTANT: To maximise the app's performance and speed, images should be less than 1MB, but preferably as small as possible. Use JPG when the image is photographic, and PNG for graphics and text. To convert one to the other, go to png2jpg.com or jpg2png.com. To compress large images, either PNG or JPG, use tinypng.com.

App icon

The app icon is the visual anchor for your app. It should reflect your Society app, while remaining sharp and legible at a small scale. Because iOS and Android crop icons in a different way, two different icons are needed to make sure it looks good on both platforms. For iOS, only the corners are rounded. For Android, a mask is applied and more of the original image is cropped. Try to make your artwork no bigger than 600x600px and align it in the centre of the image.

Both images should be a 1024x1024px PNG, and should have no transparency or shadow.

Google Play Store images

To submit your app to the Google Play Store, create the following images that represent your app:

  • A square icon of 512x512px. You can resize the App icon for this.

  • A feature graphic of 1024x500px

Both images should be PNG without transparency or shadow. Please note that the corners of the image will be automatically rounded, so important information should be kept from the edges.

Welcome screen

The welcome or splash screen is displayed while the app opens and loads. The length of time for which the welcome screen appears depends on the size of the app and the speed of the device.

The welcome screen is composed of a square logo (1024x1024px, see dashed line in the image below) on top of a background color. Make sure the logo has transparency, so that it looks good on the background color.

Confirmation and password reset email

If you're allowing your users to log in to the app with their email address, you can brand the emails that are sent. These are the mail to verify a user's email address or to reset their password. You can set a header image (900x300px) and a hexadecimal (e.g. #FFFFFF) accent color, used for titles, buttons and links.

Invite email

If you are using the invite feature from the attendee list, you can brand the emails that are sent. You can set a header image (900x450px) and a hexadecimal (e.g. #FFFFFF) accent color, used for titles, buttons and links.

background

If a user signs in to the web app through the menu top right, they see a full screen image behind the section where they can sign in. This image should be 1600x900px. Please note that depending on the user's screen size, parts of it will be cut off, so don't place important content near the edges.

News feed background

Behind the news feed, a square image (3000x3000px) is shown on top of a customizable background color (hexadecimal, e.g. #FFFFFF). This image is resized for all screen sizes, but remains square. If you use PNG, you can add a gradient from transparent to solid to the bottom of the image, so that it transitions nicely the background color.

News feed banners

Optionally, you can add one or multiple banners (2400x600px) above the first news message, that will be displayed as a slideshow.

People images


You can change the default background image behind all person profiles. This image will be used for all person pages in this event. This image should have a size of 1200x600px.

Profile picture

For speaker or presenter images, we require the profile picture with a size of 600x600px. Faces should be positioned in the centre of the photo as they will be cropped to a circle.
