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.
Combined with well-designed interface along with powerful features, KineMaster is a convenient video editing tool for Android. It enables drag-n-drop technique to import different media files easily. KineMaster offers remarkable levels of control over the editing process to create professional videos quickly. You can add different types of transition in between video fragments, or insert blocks of texts or subtitles.
KineMaster is one of the most powerful video editor apps available. You can do the basics like most of these other video editors can. However, this one includes multiple video, image and effect layers. Additionally, there are audio filters, chroma key (for your green screen fans out there), various video effects, transitions, and more. It's not as powerful as a full desktop editor. However, this gets much closer than most other competitors. We would recommend this for actual video production (at least for stuff like YouTube). You can use it for free in trial mode for a while. However, you'll need the $4.99 per month subscription to get everything forever.
