I'm 73 and I make videos for the same reason, posterity.
I use my 2020 iPhone 7 and it works just fine- I tried an iPad mini and sent it back. (Dell inspiron 15 3000) to load from my phone to upload to you tube-after you do it a couple times it's easy-
and it gets easier as we get older-
I use the lap top in the open position to support my phone with the screen and I'm only a couple of feet away from the phone.
That works better than the phone tripod I have. I guess the screen reflects the sound into the phone directly, It's like the sound goes past the phone on the tripod- IDK the why it works better the way I do it, but, it does.
