More than a billion people use the instant chat and messaging app, WhatsApp, whose latest versions are constantly can be downloaded, updated and installed on Android smartphones for free. It can be used for messages, calls, sending and receiving of various media, such as voicemails, documents, photos, videos, also for free.
All messages, files, voice, images, sent through this application are protected with an end-to-end encryption. In addition there is a video call feature with another WA user. Someone can chat one-on-one or within a group. During the chat, texts and emojis can also be sent, voice messages recorded earlier can be created, photos can be taken and adjusted. Because the services are free, someone will think that they have to put up with third-party ads, but they will not appear. No pop-up ads during chat.
Some of the Pros is using the Broadcast List to send a message to multiple contacts at once, or there is no need for a headset when an audio message arrives in a public place where there is noise, simply put the smartphone close to your ear.
Some of the Cons is even though it now has Stories feature, it still hasn’t made any face filters feature available yet, unlike Snapchat, Facebook, or Instagram.
