I don't see how they could better it
It does exactly what it's supposed to on my touch.
I just think the UI is s***. Very badly designed. It kinda does everything you want it to, but it doesn't make it as easy as it should be.
A well-written app *easily* beats a web browser as an interface.
For example, I tend to grab my iPad and use Alien Blue instead of going to reddit.com, even when I'm sat at my desktop machine. I would never use Tapatalk if I could open a forum site in my desktop browser.
Tapatalk is a complete mess.
