About this app

BILD.os is a field app for construction site managers and foremen. Say what just happened on site, and it becomes structured work: tasks with owners and dates, field updates on the record, and a log nobody has to write up later.

TALK INSTEAD OF TYPING
Hold the mic and describe the situation the way you would to a colleague. "Third floor bathroom, the old riser is more corroded than the survey showed, we need to replace the full run up to the fifth floor." BILD.os turns that into the tasks it implies, and shows them to you before anything is created. You approve, edit, or throw them away.

BUILT FOR BAD SIGNAL
Stairwells, basements and lift shafts are where notes get lost. Everything you capture is written to the phone first and uploaded when there is a connection again. Walk out of range mid-sentence and the note is still there when you come back.

CAPTURE HOWEVER SUITS THE MOMENT
Voice when your hands are dirty. Photos when it is easier to show than describe — mark them up to point at the crack you mean. Typed notes when the site is too loud to talk.

THE DAY'S WORK, IN ORDER
See what is overdue, what is due today, and what is coming. Tasks carry subtasks, dates and the person responsible. Tick them off as they are finished.

A SITE LOG THAT WRITES ITSELF
Every note, photo and completed task lands in one timeline with who did it and when. Filter by date, by person, by trade or by task. When someone asks what happened three weeks ago, the answer is already there.

REVIEW BEFORE IT COUNTS
Work suggested from the field waits for an admin to approve it. Nothing enters the plan because a phone misheard a word.

FOR THE WHOLE CREW
Project managers set up projects, manage members and edit details from the site. Employees see the work assigned to them. Everyone is on the same plan.

SPEAK IN ANY LANGUAGE
The app itself is available in Finnish and English, switchable anytime. But when you're recording, speak whatever language you're comfortable in, BILD.os understands you and translates it into your project's language automatically.

BILD.os needs an account with a company already using BILD.os. If your company has not set one up yet, get in touch at hello@luju.fi.
Voice, photo and text field notes, turned into tasks by AI. For site teams.

Nothing said on site gets lost again. Voice, video, photos and notes become tasks and a log that writes itself.
