Your decision might come down to which app your friends and family use. Here, we review what each offers. Both offer everything you might want for secure communication and file sharing. Your best approach might be to download both on your smartphone and see which interface you prefer.
WhatsApp and Viber both offer:. Viber has a rich interface, but it looks cluttered. Viber has an overwhelming library of stickers that clutter and complicate the interface. If you're addicted to stickers, you'll prefer Viber.
WhatsApp isn't into stickers. However, WhatsApp has a simple, clear interface that feels comfortable and gives the impression that everything is at hand. In addition to the app availability, WhatsApp can be accessed as a web app on a computer, and Viber offers a Chrome extension in the Chrome Web Store.
Voice call quality is an important consideration. Viber has offered voice and video calling for years and is more experienced than WhatsApp. Viber delivers HD-quality voices that are crisp and clear in high-bandwidth connections. With Viber, you can transfer ongoing calls between devices. Voice quality has many aspects affecting it, apart from the services' codecs and perceived quality. One important factor is the network connection. In this respect, WhatsApp appears to be more robust, especially in re-establishing dropped calls.
Viber and WhatsApp offer video calls. There doesn't appear to be any advantage of choosing one service over the other for video calling. With Viber, you can start a secret chat and set a timer that deletes the message at the time specified. You can also set video messages to self-destruct at a specified time after the video is seen once.
WhatsApp doesn't have a self-destruct feature. You can write a message and set a timer in Kaboom and then share the message with WhatsApp. The downside? The recipient receives a link to the Kaboom online site to view the message, so the integration with WhatsApp isn't seamless.
