This is a wonderful fun app. It works great on my iPhone 6s+ and I have zero complaints. I love how the phone call option works well. Dont change a thing here. I get the notification on my AppleWatch and then have time to answer on my phone. I would like to make a few suggestions. A passcode/TouchID would be great to get in the App. It would be nice to clear a conversation without losing the contact. It would be even better if we could easily delete a conversation and have previous contacts saved to be able to start a clean conversation. A third party code review would be great. Otherwise, this isnt on par with Signal.
