Not an android user but I'd imagine their market share on itch is pretty small. If I was an android user i'd probably stick to the more established marketplaces for apps. I'd imagine its only other devs that get anything from itch for their androids. It might be a good way to test your products, but staying on the Play store or similar marketplaces lets you avoid the issue of broken software from a dev that doesn't know about mobile development and simply ported his windows product, possibly porting it wrong and making it unusable on itch, potential security issues etc.
