Pros & Cons from Real Users Pros It offers text, video and audio communication to shat in contact with family and colleagues. It's also has a mobile platform. Group chats are easy to add and share with the community. Free & Open source Provides end to end encryption Group chat and video calling 'Disappearing messages' feature Complete privacy - No IP or data logs No ads or trackers - No data collection Available across platforms and mobiles Cons It worked great for me. Nothing to share about cons. It requires a working phone number to sign up - it should be allowed to work with email for better privacy and accessibility. Apart from that it is a great app with no cons.	Pros & Cons from Real Users Pros Works well as a desktop messaging app, synced with the android version. But the alternatives are much better, thus this is not to be recommended. (+) Viber desktop application and very good sync with the desktop application. (+) Transfer of photos and videos without drop in quality. (+) It can seamlessly do group calling with more users without a drop in quality. (+) Self-erasing messages is a great way of cleaning up space. This was one of the first instant messaging app I had on my iPhone. Simple to set up and uses your phone number and instantly shows all other contacts that have Viber. It has stickers which is a fun way to communicate with friends and family. Great group calling support and quality with 20 people and more. Has message encryption so your privacy is safe. It can connect more than 200 people in group chat. Video quality is very good even on unstable connection. Funny stickers and emojis. Can join many global public community to make new friends. Love how easy it is to use to send messages internationally at no additional cost when they also have Viber. Cons This software insists to interrupt you by its updates, which become available very frequently, and which you have no choice but to be interrupted by, since the app doesn't give up till you restart it, then opens up its blog page each time. There is no option to turn this incredibly annoying behaviour off. Irritated customers writing reviews such as this one, ensue. Also, the advertising is very obtrusive. (-) No blocking of calls feature. (-) Nonavailability and limited audience base which is a drawback. (-) Too many stickers and gifs make it annoying. (-) There is no backup option for your chat like in WhatsApp. Needs more innovative features to catch up with its competitors. App crashes sometimes and have to close the app via switcher and open again. Sometimes doesn't detect mobile data. I never faced any issue on usage of this app. It works very well for what it made for. Super easy to use which I can't think of any cons.
