I use my iPhone, but nowhere nearly as involved as a spreadsheet. I just use my finger to write the lens/aperture in a notetaking app and take a pic of it before I start using the lens. Then in post the info is there and I can transfer it to the individual files via ExifChanger.

Looks like this:



MyScript Memo app

All I have to do is remember to actually record the data on the phone.
