We are so excited that you are building an app with us. Whether it’s your first time or you are refreshing your app’s look, we are here to help you make it look the part and be a valuable mobile extension of your brand.

  • Pro Tip: Check out our full Design Guide, made by our expert Design Team, for best practices, visual examples, and tips to optimize all of the design options throughout your app!

App Icon 

The app icon is very first thing your user sees when downloading or using your app. It also lives on your Giving pages. Make sure it is an icon that is easily recognizable and clearly legible for your brand. Keep text on your icon minimal. Use your primary color as either the color of the icon or background color.

Size: 1024x1024px

Format: PNG (no transparency)

Usage: Display on phone home page, receipt pages, and on any giving form.

Important: The icon should be full-bleed, with no shadows or corners applied, and not transparent. Additionally, the icon can not be changed dynamically after your app is live.

Splash Screen

The splash screen is your branded loading screen. This is a full frame static screen that welcomes your user to the app when loading. Consider using an image or dynamic design elements that showcases the personality of your brand. Remember, for consistency, it is best practices to use the same color palette you are using across the app. Feel free to add your tag line or branded copy to add personality as well.

Home Background

The Home Screen is where all of the magic happens! Your buttons live here for easy navigation between features. You will need to build a background at multiple sizes. Include branding (you can also include: color, imagery, service information, and pretty much whatever you want!) You also have 4 different grid height ratios to choose from.

Grid Height Ratio

You will need to choose the grid height percentage at which you’d like to display your buttons. Because the Home Screen background image is set behind the buttons, 40, 60, 80 or 100% of the image will be semi-covered by feature buttons at the bottom, while the remainder of the display will be available as your header.

Feature Buttons 

Buttons help your user navigate to the features and content they want to interact with.
Readability when creating buttons is crucial. All buttons — icon or image-based —
require the name of the button designed as part of the image.



Pro Tip: When creating buttons consider using design resources like Unsplash for images and Nounproject for icons.

We have some easy to use design templates that you can download here. (Templates include .psds for icon, all screen sizes, and buttons.)

You can also access our Feature Images Library which includes styled themes for your buttons.


Additional Information / Q&A

Q: Does resolution affect my images?

A: No. The PPI or DPI of an image displayed on-screen or in your app doesn't change the way it's displayed. A standard PPI to work from is 72, and will work great in-app and on-screen.
