As we know there is no built-in feature in android camera to shoot slow motion videos, we have to use third party app to make or convert videos into slow motion, there are many apps and tools available for this, but here I am talking about free any easy to use app that is “Slow motion video FX” it’s a free, light weight and very easy to use app.
This app can record slow motion video direct from your phone camera or you can choose from phone gallery, not only this record your speech and make it slow or fast, record video and make it slow or fast motion.
