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.
When it comes to video editing on iPhone, no other app comes even close to the feature set that is packed inside LumaFusion. It is the only outright paid app on this list and it deserve every cent. The app is not only used by YouTubers but even mobile journalists and professional video producers who don’t want to carry heavy camera gear and editing rig where they go.
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.
World-Class Video Apps
Though Mac users don't have the sheer number of software choices available for PCs, Apple fans interested in editing video are well served, by four products in particular. At the entry level, the surprisingly capable and enjoyable-to-use iMovie comes free with every Mac sold since at least 2011. iMovie only offers two video tracks, but does good job with chroma-keying, and its Trailers feature makes it easy to produce slick, Hollywood-style productions.
