The Heroic app has been created for devices using iOS 14.5 or higher. At this time, it is not optimized for anything smaller than 375px and we highly recommend using a newer phone for the greatest app experience!
Specifically, the app is designed for an iPhone X+ size but will work on any iPhone that has a high enough version, there just maybe some UI issues. For example, there are known issues with an iPhone 8 screen size.
