Sorry, do you mean on Andriod or IOS? (I live in Sweden ... and can download on IOS) If Android, then it is because we are waiting for Google Playstore Approval.
Yeah, this has been requested a few times. I don't come from a hosting background (Outside of managing my own VPSs) so I don't feel it's something I can personally do (at a level of service I'd be happy with) but the idea of partnering with someone that has experience is something I've though about; The tricky part is finding someone I can trust enough to send users to.
For sure. Honestly, I would love to have an established open-source respecting company like RedHat come along and say "We'll be your official hosting partner, we'll handle hosting, payments and offer these services, we'll need x hours from you per week for support, otherwise focus on the project, we'll give you £x per month, You retain ownership and other revenue streams."
A bit idealist and of course the contract would be more complicated, but to focus on the project while having established support would be ideal.
I think this isn't a good strategy for the project, at a commercial level. They currently have a well define niche. Competing in a much larger market without a clear competitive advantage won't work.
