great when it works, however i continually experience issues daily with phone calls (using for international business calls) never been able to receive or download any voice messages sent from contacts (download failed), have had trouble taking/sending pictures through the app (freezes then app shuts down) and currently i can not send any messages to one of my contacts. tried restarting phone, app, check settings, nothing is working. good app, but mostly frustrating, it doesnt work when needed

Was a great app, worked very well(needs polishing on UI). Sucks that they moved to a pay version,but understandable.Wish they'd keep a free version available or have a lower priced option. Also a pay once, have it for life option would be much better than a monthly pay or yearly. Luckily options exist like Vipole, ghostly, upco, cliq, briar, clearkeep surespot, secret messenger, zom, crait and wire are still available for free. Threema is $3 for life.

(update) I still can't add anyone. This time when I send the friend request the recipient doesn't receive it. (previous comment follows) I can't give it a good rating. I have installed on 3 devices and it remains impossible to add anyone. If I try to add someone it simply says "waiting for their encryption key" or something like that... And never adds them. I hit accept to friend requests and no one is ever added. Kind of useless to have a messaging app you can't add users to...
