Viber began life as a voice calling app. You used to be able to call people on the service along with regular phone calls. It has since evolved into a full-fledged messaging service. You can still make phone calls like you could before (for a fee). You can also text chat, video call, and more. It also features encryption on voice, text, and video calls between Viber users. There are a few extra fun features like hidden chats as well. It's a little bit heavier, similar to Facebook Messenger. However, it's otherwise not bad. The app isn't overly popular in the United States, but it's quite big Internationally. The in-app purchases are for things like stickers and other personalization items.
Other measures of performance include startup time and simple stability. Again, video editing is a taxing activity for any computer, involving many components. In the past, video editing programs took longer than most other apps to start up, and unexpected shutdowns were unfortunately common, even in top apps from top developers such as Adobe and Apple. The stability situation has greatly improved, but the complexity of the process, which increases as more powerful effects are added, means crashes will likely never be fully eliminated, and they often raise their ugly heads after a program update, as I found with the latest version of Pinnacle Studio.
Businesses are moving further apart. That is, many small to midsize businesses (SMBs) are becoming spread out across many geographic locations, which brings complex challenges for communication, even for employees that work in-house. Add customers and partners to the mix, and it's difficult to think about talking to all of these folks without extensive travel, which brings restrictive costs. This is where video conferencing can deliver a serious boost to your company's bottom line.
Signal Private Messenger is one of the most popular privacy chat apps. It features end-to-end encryption for all messages, voice calls, and video chats between two Signal users. It focuses a lot on individual chats. There are group chat features, but it's mostly for personal use. This is one of the biggest differences between it and rival privacy chat app Telegram. Video calls worked fine in our testing so we have no trouble recommending them. It's a neat way to get some encrypted chats as well. The app is also completely free and open source. You can't really go wrong with it, but there are better video chat apps if you need group video chats.
Other features I look at include the number of participants allowed on a call and the number of video feeds allowed simultaneously. The most generous is Adobe Connect, which is unlimited, but some offer as few as four participants at a time. Consider how important this is to your company. Most services let you record meetings, and a few let you edit the recording right within the software. These recorded meetings can then be used for your records or as webinars for anyone who missed the meeting or for new employees.
