Adobe Premiere Clip enables you to edit any video right from your Android device quickly. It is fast and fun to use. The best feature about Clip is the automatic video creation capability, i.e., the app can automatically create videos for you with any photos or clips that you choose. Moreover, you can also create your videos with its multiple video editing functions like cutting, trimming, adding transitions, music, filters, effects, etc.
Kik is a popular video chat app. It's actually a text chat app with video chat features. The app features single or group chats, support for most types of media sharing (GIFs, video, images, etc), and some extra stuff like stickers. Kik is a popular chat service for mobile gamers. For instance, I've used it for Clash of Clans in the past. It also doesn't rely on your phone number. You just need a standard user name to use much like Skype and unlike WhatsApp or Google Duo. It's colorful, so those who want something a little more serious may need to keep looking. Otherwise, Kik is a perfectly acceptable app for both video and text chats.
