Just my two cents here regarding the choice for future platform development:
Maybe you could give already paying Kagi and Orion users the option to fill out a simple survey to let you know which OS' they are using (besides MacOS and iOS). Maybe new users too during the sign up process (voluntarily of course). Would that help you plan which platforms to prioritize in the future?
For instance, I suspect there might be a ton of MacOS users who actually have Android phones instead of iPhones. So that may be a low-hanging fruit that benefits and encourages already paying customers while also opening up to lots of potential, new, Android-only users.
Anyway, just a thought!
