Construction site app

Daily logs, safety and deficiencies, even with no signal.

Construction software often assumes a desk and a signal. We build site apps for the opposite: a phone in a work glove in a concrete basement. Logs, safety forms and deficiencies are captured where the work happens and become a record you can search when it matters.

// what matters here

What is different in this industry.

Offline first

Everything works with no signal and syncs when the phone finds one, so a log written on the fifth floor of a steel frame is not lost.

Fast enough to actually use

Large buttons, few steps and photos that attach themselves to the right item. If a form takes longer than paper, crews will go back to paper.

A record that holds up

Each entry is stamped with who, when and where, and edits are kept, so the site record stands up in a claim, an insurer's review or a safety inspection.

Fits the tools you already use

We connect to Procore, your accounting system or your document storage instead of asking the office to switch.

Site app for logs and safety

Hypothetical. Not a client, not a result.

// The problem

A general contractor keeps daily logs, safety inspections and deficiency lists on paper and in photos on personal phones, so nothing is searchable when a dispute or an inspection comes.

// What we would build

An iOS and Android app that works offline on site, with daily logs, safety forms, toolbox talk sign-in and deficiency lists pinned to drawings, and a web dashboard for project managers across every job.

// What is in it

Tools and materials tracked from the yard to each site, with QR labels and GPS trackers on the larger equipment
Daily logs with weather, crews on site, deliveries and photos
Safety inspections and toolbox talks signed on the phone, in the worker's language
Deficiencies pinned to the drawing, assigned to a trade and closed with a photo
Works offline in a basement or a steel frame and syncs when it finds a signal
A dashboard of every job's logs, open items and safety records
Exports for owners, insurers and safety regulators

// questions

Questions we get about this.

Does the site app work with no cell signal?

Yes. Logs, forms, photos and drawings are stored on the phone and sent when the phone is back online. Conflicts are resolved by rules you agree with us.

Can trades use the contractor's site app?

Yes, with their own sign-in and only the jobs and items assigned to them. They do not see your other projects or your costs.

Do forms follow WorkSafeBC or provincial rules?

The forms are yours. We build the inspections, toolbox talks and incident reports your safety team uses for WorkSafeBC or your province's regulator, and change them as they change.
