The work diary is a day, as a list of short voice entries. The technician taps the capture button at the truck, talks for thirty seconds (the site walk, the conversation with the foreman, the voicemail they returned), and the entry lands in the diary with its time, a transcript, the recording, and tags for the company and the quote it relates to. The diary shows entries per day, total time recorded, and how many have been reviewed. A daily disposition summarises the day, and anything that needs review is flagged.

The capture button is on every screen. Record, stop, done. Transcription and timestamp are automatic.
Each entry is tied to a company and, where relevant, a quote number, so the diary is also the customer's history.
Entries show as reviewed or needing review. The office works the flagged ones; the rest are already filed.
Entries, total minutes, and reviewed count per day, with the week across the top to move between days.
Field notes do not get written because writing is slower than the work it describes, happens after the moment, and never visibly helps the person writing. Speaking is faster than the work, happens in the moment, and comes back to the same technician at the next visit. That is the whole reason the diary is voice-first.
It also means the office hears what actually happened on site, in the technician's own words, rather than "done" in a status field.
