3 stars: It works. But it has only one issue: does not support greek characters. So once I receive a message in Greek I just get a notice that I received a message (and the option to reply in viber) and not the whole message -which that's why I installed unseen to choose which I want to read or not, because obviously cannot decode it.
5 stars: I use UNSEEN for FB msgr...works very well and fits my needs. Would not mind paying for an added feature allowing option to view pics received w/o ticking the read on....but that's maybe just me. Thanks for this handy app.
4 stars: It does exactly what it says it does! If it could group all messages a little better, I'd give it 5 stars. Right now they come in weird unorganized groups instead of one thread, like in messenger.
3 stars: Nice but it's not directly into the WhatsApp.. It uses another theme access to read messages unknown. Why can't the App be with your default messenger part that's already installed? That'd be kinda cool if it could notificate unseen messages using the same default App that is installed.
4 stars: **UPDATE** 5/11/17 Seems to be working better with group chats. I like it. (Older review) I'm not sure if it works for group chats. When I click on group chat a pop up shows "Unfortunately, Unseen has stopped. Options Report or OK." Otherwise it works good.
4 stars: Sync all the unseen messages on all the allowed apps. I downloaded this app after I have a message of someone I don't want ...
