the best way to download a Reddit video on a mobile:

• If you have an Android smartphone, you can simply download a Reddit Video Downloader app from the Google Play Store. I recommend utilising any of these apps to download Reddit videos on your Android phone with a single tap.
• You may either go to Reddit, touch the Share icon, and choose the app from the drop-down menu, or simply copy-paste the URL of the video you want to download. The audio component of the downloaded movie will be preserved (unlike some other apps).
• This free Reddit video downloader is compatible with Android 7.0 and subsequent versions.
• To use it to download videos, you must first go to Reddit, copy the video's URL, and then submit it to the app later.
• You may also select a video on Reddit, touch the Share icon, and opt to load it directly into the app.
• The programme will analyse the video and allow you to download it in the highest quality (with audio) to your device.
