ive been using tapatalk beta for about 3 months, and its much better than the old tapatalk.
At its regular price of £2.50/$3 I would say its worth it if you use a lot of forums (i have about 9 forums on mine, some of which i dont use very often, but its useful for getting notifications of personal messages or subscribed topics)
At 69p/99c theres not really much to lose in trying it out. Remember you have a 20 minute cooling off period on the android play store to claim a refund if you dont like it.
onto the forum. im having no problems using tt beta. push notifications are working as i just got a pm on my phone. I know theres an issue with thank yous, im looking into that.
it depends how you use tapatalk. I use it as the secondary way of viewing forums, recieving pm's when im out and about, using the pc most of the time. The way we browse is rapidly changing, i spent four months this year rebuilding my forum theme so that it was designed to handle mobiles, tablets, and desktop all at once, but its a major undertaking.
