No point in developing our own when third parties have much better apps. I use Tapatalk personally although I generally prefer a regular web browser and don't like reading my my phone or iPad as much as from a computer.
I found Tapatalk preferable to Forum Runner. I can't remember why. I think it had something to do with how I could do something in Tapatalk that Forum Runner couldn't do. I just can't remember what it was.
I use Tapatalk quite a bit. It's great for reading threads, not so much for replying. Generally, I read stuff throughout the day on my phone and then wait until I'm on the computer to reply/post.
