I would just use a cloud product like Google drive or Google notes for this. Then at the end of the day paste it into the correct location in the log.

I've thought about this type of tracking in the past, but I haven't been confident enough that it would actually find useful patterns to put in the work to implement it.

If you're using a phone, you could email yourself with a journal specific subject then use an API to automatically add those observations to a log. (Might be able to do that with Google Drive or notes too, I'm not sure if they have API hooks).

If you don't want to keep a phone, a small journal is also a possibility.
