Apps are confusing

Why so many different apps? Pics viewer camera for example, should be 1 app IMHO.

Some app controls are different from app to app

Because they do different things and are built with totally different technologies. LeiaPix is a social media platform like Instagram, and is primarily written in Java. LeiaViewer is a model viewer for 3D models like .obj and .fbx and is created in Unity. LeiaCam is a 3D camera app written primarily in Kotlin.

The apps are so different it doesn’t make sense to put them together. Imagine if to take a picture on your phone you had to open up Instagram and swipe through 3D models first before you could take a photo.
