I've developed a web-based RSS reader and it seems the next logical step would be to create apps for the various mobile platforms (iOS, Android, etc.). But I have no idea where to begin and I would have no way of testing my apps. (I don't own any mobile phone/tablet and I don't want to buy an array of devices just to test one app.) I've heard there are ways to create a mobile app once and then port it to various devices, but that route seems to require some usability tradeoffs.
I'm thinking it would be it would just make more sense to build a mobile-friendly version of my rss reader that has a sleek "app" feel to it. But if it's that easy, why do so many sites even bother with the time and expense of creating a native app?
I literally haven't spent more than five minutes using a smartphone in my lifetime. (No, I'm not a luddite, I just have no need for a mobile device. Also I am Canadian, and the telcos here charge exorbitant rates I'd rather not pay.)
