3D model organizer/gallery mobile app?

I'm on the lookout for an Android app that could serve as a gallery for locally-stored 3D models. The app should support model formats with textures too (say, and obj with jpg texture file). Most apps are either single-instance model viewer or a full-fledged 3D scanning app. Online platforms are reasonable substitute for places with reliable internet, but it's always dicey for models under an embargo.

I have a lot of models built on PC and would love to be able to show them on the fly using my phone. Plus, if I'm testing multiple scanning apps, having a middleman viewer/gallery would make comparing these programs' output more reliable.

If no such app exists yet, think of this as a plea to the FOSS community to consider building one.
