How do I add a voiceover to my reel after I've already edited the video?

Record your voiceover as the final editing step, once you know exactly how many seconds you need to fill. Most editing apps have a built-in voiceover or audio recording feature — just tap the audio or voiceover button, record directly on your phone, and the app will add it as a new audio layer over your video. This works in mobile editing apps and even in some platforms’ native editors. After adding your voiceover, you can also add closed captions so viewers watching on mute can still follow along.
