Messaging good, calls okay

Really thankful for this app, because I dont want unwarranted snooping on my conversations. Its free too, which is kind. Im no security expert, so I dont actually know how secure it is. Messaging works most of the time, calls can be iffy. I sometimes have trouble calling at all (it says its connected but I cant hear anyone) and when I can hear someone, it isnt always clear and easy to make out what theyre saying.
