Plan for mobile apps is to build those on top of the Rust core, using methods similar to the FullStory posts here over the past couple of weeks. We had a Xamarin thing working at one point, but it was... Xamarin. We can also work through WebBluetooth on android devices (and there's a WebBLE iOS browser in the store), so that's a crappy-but-workable option.

Standing up services is something I really want to get to, with the plan being to run a containerizable system with optional hosting similar to Discourse/Matomo/etc models, but first I gotta stop rewriting the damn core library. The problems of making your back yard shed hobby project a business, right?
