The HALO app supports fully custom graphics in your booth’s Preset settings.
This guide explains how to size your designs correctly, what file types are supported, and where each graphic appears in the app.
How to Design for the App
Review your available graphics
Your software tier determines what graphic features you can customize (e.g., overlays, logos, green screen).
📍 Check your plan details to confirm which graphic types are available in your settings for picture customizations and booth appearance customizations.Set up your booth configuration
Decide on your iPad orientation, layout style (strip, single frame, etc.), crop type, margin thickness, and whether you'll combine graphics like logos and overlays.Note the required sizing
Most design programs ask for canvas dimensions first — find sizing guidelines below. Whenever possible, a dynamic sizing recommendation (which will accommodate for things like margin thickness and added logos) is listed directly in your preset settings.Create your graphics
Use your preferred editing tool.
💡 If you’re new to design, we’ve recommended a few easy-to-use apps you can explore.Export your files
Choose PNG when you need transparency (e.g., overlays, props, stickers).Upload to your Preset and test
Import graphics into your Preset, sync them to the app, and test how everything looks.
