Site diary app that captures what happened, on the day
it happened

A live daily record of work done, workforce, weather, incidents and photos. Captured on mobile at the moment, not typed up at the end of the week from memory.

Built so 95% of the diary is already written before the site manager opens it

THE PROBLEM

The Word doc diary vs the live mobile diary.

A traditional site diary is a Word document opened Friday afternoon, populated from memory, and rarely referenced again. When a dispute happens six months later, the diary is thin, contradictory, or missing.

A Plexa diary is captured live: photos taken on the deck, workforce numbers logged at the toolbox, weather recorded automatically, incidents timestamped as they occur.

The mobile diary in action

The site manager opens the diary on the phone at 7am. It’s already pre-populated with today’s weather, expected workforce and scheduled trades. They add a photo, a note, a variation reference. Diary closed by 4pm, not 8pm.
