It is such a shame and pity that it comes from China. It killed all of the buzz for me in an instant. I have nothing against Chinese people, but an app that has done something never done before with Chinglish in it - nope.
Everybody is talking about high level conspiracies regarding NSA, overseas intelligence agencies and whatsoever.
But the real concern should be about simply getting scammed! Of course our(end user) data is not safe, it was not designed from the very start to be so. I have no problem with NSA and Apple reading my messages because I am sure that they won't use the credit card linked to my account without my consent.
This... thing is a bit different. It is run by a third party provider somewhere outside of European and American jurisdictions. My concern is that if this app was created by Europeans or Americans, I would trust it my password and account, because I would have a tiny fraction of luck in case my account gets compromised and I loose money. There would be a possibility of an investigation, a court and a punishment. This, my friends, is a bit different scenario. If people get their accounts compromised and money gets stolen, Apple is not going to do a thing about it for two simple reasons: 1) Who wants to argue with China? What is the chance of even finding the physical location of the server all the data gets relayed back to? 2) Apple never authorised the use of third party apps.
This is my concern about China, nothing else. I would love to use this app for my every day needs, I would even pay for it! But the chance of my account being stolen with no possible outcome positive for me just rustles my jimmies.
There's also the possibility of an investigation, court case and punishment in China.
And I wager the chances of you getting any money back in either case is about the same.
