Me too, me too, me too. The only thing I ever attempt to do on my phone is to read posts, and half the time they don't load properly. I would love to have an app.
A Booklikes app would be awesome! Although I have no problems doing anything from my phone that I would be able to do on my computer. Maybe it's because I have a different phone....I have an HTC. The app would be convenient though, but only if it was done right. I can't stand the Goodreads app because there's so much you can't do on it, like comment on someone's profile, or access things like Listopia or giveaways, and you can't send recommendations either.
I use Android (tablet and phone), and while I can do pretty much everything I would on a desktop, I find that the BL website often crashes my browser when all I'm doing is trying to read reviews.
I really do hope they make a Booklikes APP,but only if it's better than the GR app.
My usage is similar to Tony's, although I have used my iPhone on BL when desperate and haven't had any issues.
But I would LOVE an app that allowed me to bar-code scan and assign books to specific shelves. I'd even take an app that did only that. (Although I know BL users should have full functionality.)
