For vlogs, just record it in 720P on your iPhone. Just use the selfie mode camera, or the front facing one and turn around your phone.

If you have the iPhone Pro, put it in Ultra Wide mode, and have the iPhone face you while vlogging. It is like a more streamlined GoPro; you can directly airdrop the videos to your other devices, whether it be your iPad or MacBook laptop. We’re better yet, you could directly upload your vlogs to YouTube from your iPhone. No intermediary required.

I am also just using the basic iPhone SE and it works fine.
