I’m glad to let you know that MotionBook 1.5 is now available for downloading. This update comes with a useful “Add Photo” tool, which allows you to insert any photo to your flipbook pages or the background page. You can find this new tool in the Advanced Editing tool set.
Oh, and we also fixed a few annoying bugs you may have seen on iOS 13. Now it should just work as expected on the latest iOS (or iPadOS).
