Adobe Premiere is one of the most popular video editors on the planet, which has now also hit Android phones. It's called Adobe Premiere Rush and is a compact smartphone editor experience.
Previously this version only existed for iOS but was recently released for Android. The app supports synchronization of desktop projects to the mobile phone, an extremely useful tool.
You can find Adobe Premiere Rush on the Play Store or the App Store. Both are available completely free of charge. If you are looking for a fast and efficient editor for your 'on the go' videos, this is the best solution.
The goal is to make mobile video editing easy and intuitive. There are several video editing apps in the app stores but most suffer from annoying ads or unintuitive interfaces.
Adobe Premiere Rush is for simple everyday videos
Of course you won't do any high production with Premiere Rush because the tools are limited compared to the desktop version. However, it remains a fairly complete editor.
When you have your recording you can crop the image, the audio, add transitions, filters, format, etc. You even have tools considered more advanced as adding layers with different recordings.
There is a lot to explore in this app. If you already use Adobe Premiere on your computer, several options will be familiar to you. The interface is simply the same but more compact so the transition is easy.
If you have a tablet, you can still shoot with your phone and sync files, then have access on a larger screen to edit. Since the app saves projects across all devices, you can start editing on your phone and finish it at home on your computer.
