There's a gacha, it's mostly for props to use in Dioramas, where you can pose as many figures and props as the app will allow you to and post them to the in-app image feed. Only trouble is, you have to choose a "world" to make a new Diorama in, which effectively locks each figure to its respective series - so making crossover pictures is hard, barring "shot reverse-shot" trickery that I've seen users on this app do.
The Gallery mode doesn't impose the "world" restriction, instead letting you place the figures (stands included lol) on a desk, along with Real Human Desk props that I think are exclusive to the Gallery mode.
Or you can just view/pose a figure on its own on a basic backdrop without all those pesky props (there's also an AR mode that I can't try on any of my devices).
Either way, the posing can be a bit awkward to do on a smaller phone screen - especially when you're trying to do fine details - but it still works fairly well. As far as I can tell, each figure's articulation is fairly close to its real world counterpart, which was probably the intention wwwww
As of posting, the app is celebrating its 1.5th anniversary and has added a "toon" world, whose respective figures so far (barring one) are more like MMD models than digitized real-life figures - but at least they're not arbitrarily divided like the different series Gundam figures (yet!)
It's uh... interesting. Interesting enough that I can't really form an opinion on it either way, so this ends up coming off more as an overview of the app than anything. Oops
