WakaTime is the most popular automatic time tracker for devs. We release a report each January about the time devs spend coding using our platform [0] and the average is 48 mins per day. However, there's room for segmenting by things like languages, editors, job description, student vs full time vs contract. Maybe this year we'll segment our yearly report to show daily average segmented by these attributes.

Does this include time in the terminal using a REPL to poke around in the code or debug things?

Yes, using https://wakatime.com/desktop since it tracks any app even without a plugin.
