Daily diary → live schedule

Log the day. Watch your schedule update itself.

SiteDiary Pro is a construction site diary wired straight into a live Gantt chart and CPM schedule. Note a delay this morning, and your progress path, production rate and cost are already recalculated by lunch.

The old way

Paper diary in the site office
Spreadsheet nobody re-opens
Schedule that's three revisions out of date

One entry. One schedule. One number everyone trusts.

How the link works

Three steps, one record

01 — On site

Log the day

Weather, deliveries, visitors, plant, labour, RFIs and delays — captured in the field in minutes, offline if you need to.

02 — Automatically

Your schedule reacts

Every entry maps onto your live Gantt chart. Finish-to-start dependencies shift, and one tap overlays the critical path so you know exactly what's driving your completion date.

03 — Anytime

Export the proof

A clean, print-ready PDF with the critical path highlighted — ready for the client, the QS or the file, with no re-typing.

Questions

Before you install

What is a construction site diary app?

It replaces the paper daily log or site journal that foremen and site managers fill in every day — weather, deliveries, visitors, labour, plant, delays and notes — with a searchable digital record that syncs to the office.

Does it work offline on remote sites?

Yes. SiteDiary Pro is offline-first, so diary entries, schedule updates and reports all work with no signal. Everything syncs in the background once you're back in range.

What's CPM scheduling, and why should a foreman care?

Critical Path Method scheduling identifies which activities have zero slack and are directly driving your completion date. SiteDiary Pro overlays this on your Gantt chart with one tap, so you always know which delay actually matters.

Is my project data shared with anyone?

No. SiteDiary Pro's Google Play data safety declaration states no data is collected and no data is shared with third parties.

Can I run more than one job site at a time?

Yes. Standard supports up to 5 concurrent projects and Pro supports unlimited concurrent projects, each with full historical diary navigation.

Your next diary entry could already be a schedule update.
