We're so glad you asked! Why, yes, we do have a mobile app for iOS — you can download NeonMob Trading Cards for IPhone right here in the App Store.
Our Android app is no longer in development. We may develop an Android app in the future, but for now we are focusing our efforts on web and iOS. However, you can still add your name to a list to be notifed if we do release an Android app in the future: add your email to the Android app notification list.
