iMovie is a part of Apple’s own suite of products for iOS (and macOS), and is a great video editor app for iPhone that you can try. While you may want to use a more powerful editing software on your Mac, iMovie is more than capable of handling video editing on the iPhone. The app is included with the newer generations of iPhones, and you can use it right out of the box to make some awesome videos directly on your iPhone.
Another program, VSDC Video Editor Pro, simply has too outdated an interface, making common tasks difficult. Longtime pro video editors will note the absence of Avid Media Composer, which is simply too unwieldy for PCMag's primarily consumer audience. There are a couple of more interesting applications—NCH VideoPad and AVS Video Editor among them—that we simply haven't tested yet.
ActionDirector is one of the most popular video editing apps on PC. It's also available on Android. It does the basics. You can import clips, edit them, and render the video. You can do things like add your own music, trim and cut video, add text, employ slow motion, and more. It's one of the few video editor apps that also supports 4K video. You'll have to check and see if your device supports it, though. The developers have a nifty tool linked in the Google Play Store to see if yours can. It also gets frequent updates.
Any smart doorbell worth its salt is equipped with a video camera that sends an alert to your phone along with a live video stream when the doorbell button is pressed. Video is accessed via a mobile app that is also used to install the device, configure wireless settings, and set up alerts. You'll pay more for doorbells that offer features like 1080p video, motion detection, two-way audio that lets you speak with whoever is out there, and on-demand video streaming. To avoid false alerts from passing cars, high winds, and any critters you may have roaming around your property, look for a doorbell cam that offers customizable motion zones.
