I am frustrated by Apple's decision to remove the apps for BTC. Ironically, I just switched from android to iphone because I prefer the iphone (better screen for texting, etc) and now it's essentially useless for cryptocurrency transactions. I do not like using android devices as I find Apple easier so I would prefer to convince Apple to allow the applications on their devices. I messaged them and their response was that there were "privacy concerns" surrounding the applications. Not particularly convincing, but support did tell me that they were hearing from a number of people who were pissed, my word not theirs. So, if you want to take the time to tell them how you feel about this issue the link is below:
