This has long been my go-to Twitter app, but after the latest updates I don't know how much longer that will be true. Too much of the day-to-day functionality has been lost.
The iPhone keyboard covers the options for both tweeting and posting photos, making it difficult to do either and impossible to make changes. I am constantly being thrown out of TweetCaster when I click on links in others' tweets, particularly tweets from the Twitter app itself. The ads are sized incorrectly for the screen, making dismissing them impossible, or else they enter a perpetual loop, repeatedly sending me to TweetCaster Store to buy gaming apps that I neither want nor were advertised on the page. The only solution is to quit not only TweetCaster but to reboot my iPhone.
I hope they find a way to fix the recent glitches, because otherwise it is one of the best and most intuitive interfaces I've used.
