A must-have instant messaging app to everyone for its popularity.
Pros & Cons:
WhatsApp is undeniably one of the popular instant messaging (IM) apps most people are using and a must-have tool on your mobile device to send text or voice messages to your contacts.
Simple and Easy to Use
Setting up WhatsApp is really simple. Upon first installation, it prompts you to key in your country code and phone number before it sends you an SMS confirmation code for you to create a user account. The app then automatically checks which of your contacts are using the service based on their phone numbers and adds them to your WhatsApp contact list.
The user interface is also clean and easy to navigate. You can access any of your WhatsApp contacts right from the Contacts tab. Next to it, you can tap the Chats or Calls tab respectively to send and receive text and voice messages, or make free internet calls, using your data connection to bypass SMS, MMS and cellular call charges.
Other than using text, emojis are built into the app so it's handy to use any of them. Stickers which are popularly used in other IM apps are however not supported in WhatsApp at time of this writing.
Same as most other IM apps, besides messaging, WhatsApp allows you to send things like documents, photos, audio, videos, contacts and even your location. Some types of files are limited in certain size for sending though.
Data Usage and Security
With settings, you can decide how to save data usage—whether you want to auto download these media files using mobile data, when connected to WiFi or when roaming. You can also set up automatic backups of your messages and media to a cloud storage such as Google Drive so that you can restore them when you reinstall WhatsApp.
In security, WhatsApp has now applied end-to-end encryption so you are ensured that the messages you send and your calls are secured. Neither WhatsApp nor third parties can break in to read or listen to them, as claimed by the service.
WhatsApp is not just confined in the small screen of a smartphone as you can use WhatsApp easily in a desktop browser with WhatsApp Web. Just head to https://web.whatsapp.com, then use WhatsApp on your phone to scan the QR code shown in a browser, you can then start using WhatsApp on a PC. Besides the Web version, the Windows and Mac OS desktop versions are also available for install and they work similarly well.
To use WhatsApp services on a desktop or laptop, it must be connected to the same WiFi network as your phone which is installed with WhatsApp. It definitely increases productivity especially when you're back at home or in office with a PC where you can type faster with a full-size keyboard, send files or copy-and-paste pieces of info to your phone’s WhatsApp contacts straightaway from your PC.
WhatsApp is free from ads and a good transition to a totally free model to end users from an annual subscription base service. It’s available and supported across multiple platforms including Android, iOS, Windows, Mac OS X, Blackberry and the Web.
