First the good. Slick UI  secure encryption and doesn't require a telephone number a huge plus point - difficult to run an SS7 attack on an iPod! Now the not so good. Based in the USA. Not open source & the big one (for me at least) the app allows for private key to be installed on any number of devices - this just opens the door for Man in Middle issues. Bottom line? Despite the negatives I kinda like Surespot for its simplicity and clean UI  so intuitive even your granny could use it. That said  it's not my main app when it comes to secure communication.
