It's a PWA and you can install it like a Native app, and as it's writen in Rust and compiled to WebAssembly it's almost as fast as a native app (and it does not send any user data to anywhere all the artwork stuff are fully local; the only thing that it send to the backend is no of users for analytics and users can opt-out in the setting).

haven't thought about it to be hoest, but now that we have AI I might be able to transalte it to Swift to make some MacOS version, or create a desktop app for Linux/... using Tauri
