A free app for Android, by Pixelab.

This is a cool app to create reverse videos. You can record a video using the app’s built-in recorder or choose one from your gallery. The app will then produce a new file containing your reversed video.  

Besides, it doesn’t require much technical knowledge and experience so anyone — regardless if they’re a beginner or a professional video editor — can use this app. Aside from it being easy to use, reverse video is also available for free on the Play Store. For creators on a tight budget, reverse video is definitely a must-download. Reverse video is compatible with devices with Android 5.0 and above.
