Currently there are 1376 reviews for the App on iTunes, and 416 of those are 1 star reviews. That’s a pretty good chunk of people having trouble. In contrast, there are 647 5 star reviews.
So it’s working fantastically well for the people that aren’t having crashing issues.
Point being – if you are having crashing problems, you’re not alone. I can’t give it a fair test on my iPhone right now, so I’m not sure how it is functioning first hand.
Hopefully Skype will get proactive on the bugs, and we’ll get a (mostly) flawless app soon.
