We build the mobile app your crews use on site and the panel your office uses to see it: hours, photos, daily reports and job status captured where the work happens, even in buildings with no signal. Flutter and React Native, one fixed price agreed before work starts.
30 minutes. We ask how your crews report today and tell you what we would build first.
Construction app development means building the software crews use on site and the view the office needs of it: time on site, photos, daily reports, punch items and job status. Apps Value builds these as Flutter and React Native apps with a web panel for supervisors, offline first because basements, risers and new builds rarely have signal. Every project is quoted as one fixed price after a discovery call. Our field software in production includes TimeFix, a workforce app for electrical contractors, and Liniowiec, an offline navigation app covering over 1,000 km of waterways.
Hours, photos and sign off recorded on the site where the work is done, not typed up from memory on Friday afternoon.
One electrical job, from the first clock in to the signed report.
The timer starts on arrival at the site, not from memory on Friday.
Office sees: crew on siteTaken in the app and attached to the job before the wall is closed.
Office sees: proof of workWhat was used goes onto the job while the crew still remembers it.
Office sees: job costSign off on the phone, even in a basement with no signal.
Office sees: job closedHours, photos and signature reach the panel once coverage returns.
Office sees: ready to invoice
The trade decides what the app has to capture first.
Many jobs a week, time per job that has to be billable, and materials that go missing between the site and the report.
Several sites at once, subcontractors on each, and a daily report assembled later from photos and phone calls.
Short projects, scope that changes on site, and client sign off that has to happen before the crew leaves.
Long linear sites, weak or no coverage, and inspections that must be provable months later.
None of them shows up on one invoice. All of them show up in payroll, billing and disputes.
Timesheets filled in from memory are the reason payroll, job costing and the client invoice disagree with each other.
The photos exist, but in a foreman's camera roll. They surface only when a client questions the bill.
The report is written hours after the shift and records what the foreman remembers rather than what happened.
Every call asking where a job stands is a status field the app should have filled in on its own.
On one of our field apps, before the software covered a particular case, crews started writing things down in their phone's notepad. Within days the data in the system and the reality on site no longer matched. A construction app has to cover the real cases from the start, or the crew builds its own workaround.
Tell us how your crews report today, and we will tell you what the first version should include.
Thomas Siudut, Co-Founder and CEO, Apps ValueClock in by location, open the job with everything needed to start it, attach photos and checklists, and collect a signature before leaving. Built for gloves, sunlight and a foreman with six minutes between tasks.
On TimeFix, the work timer had to keep running when the electrician locked the screen or placed a call from inside the app. That requirement did not come from the specification. It came from real use on real jobs, which is typical of what construction apps meet on site.
Team leads and the office see hours, jobs and reports as they arrive, assign work, and approve what the crew sent. On TimeFix this is a separate web panel for contractors and team leads, built in React on the same backend as the mobile app.
One rule we keep on every project: the office must be able to correct a record by hand. Field data will occasionally be wrong, and when it is, fixing it should take a minute in the panel, not a support ticket.
Basements, risers, underground parking and new builds before the network is installed. Crews have to finish the job with no signal and trust that everything reaches the office once coverage returns. Site photos travel in their own upload queue, separate from the form data, so a report is never held back by a dozen images on one bar of signal.
The hardest offline system we have built is Liniowiec, navigation for more than 1,000 km of inland waterways where coverage is often absent. Data is split by route segment and only new versions are downloaded, so the backend never has to send everything at once.
It passed every simulator test and still showed position errors on the water, which is why a field app is accepted only after testing in real conditions. More on the approach in offline first app development.
On site, the app competes with a notebook in a jacket pocket. If recording the hours takes longer than writing them down, the notebook wins.
Two projects, two different problems, the same discipline about what happens away from the office.
A Flutter crew app for iOS and Android with GPS based clock in, job scheduling, photo documentation and reporting, plus a React web panel for contractors and team leads. The client ran technicians across several job sites through phone calls and a shared spreadsheet; we built around the two things that ate the most office time.
Read the TimeFix case studyAn offline first Flutter app with a NestJS backend and a web admin panel, covering over 1,000 km of waterways and 18+ rivers with no connection required. Delivered from the first workshop to launch in four months, then extended in further stages.
Read the Liniowiec case studyConstruction software gets overbuilt because every department has a wish list. The first release covers one complete path from job assigned to job signed off.
Fixed price, milestone payments, and working software you can open on a phone every two weeks.
We hear from the office and from someone who works on site, map how a job moves from assignment to invoice, and write the scope in plain language. The format is described in the app discovery workshop.
The scope becomes one price with payments tied to working software. Changes are agreed before they affect the price.
Each milestone is shown on real devices, so the app at launch is the one you have been reviewing all along.
Your own team tests the app on site, during or after development. What they find in real conditions goes into the release before rollout.
Store submission on accounts in your company's name, full source code and documentation, and delivery closed with a signed acceptance protocol. Larger contracts include a one year warranty on the software.
You get one fixed number after the discovery call. Three decisions move it more than the feature list does.
Viewing jobs without signal is simple. Completing them offline, with photos and signatures that sync correctly later, is the largest single cost driver.
Crew, foreman, office and subcontractor each see different data. Every role added is another set of screens and permissions.
Writing hours and jobs back into accounting or an ERP with a documented API is routine. Older systems without one are where scope grows.
A narrow first version built around one workflow takes 10 to 14 weeks. A full system with an office panel, offline reporting and an integration takes 14 to 22 weeks. You get a specific timeline together with the fixed price, split into milestones.
Yes. We build offline first by default, which means writes as well as reads: a crew can complete a job, attach photos and collect a signature with no signal, and everything syncs when coverage returns.
Yes, as a separate role that sees only the jobs assigned to them. It usually belongs in the second phase, once your own crews use the basics daily.
Usually. A documented API makes it routine, while an older system without one is where projects expand. We confirm what is possible before you commit, and how these connections are planned is covered in field service app integration.
If it fits how your crews work, keep it. Custom makes sense when crews work around the platform, when per seat costs grow with every hire, or when the app your field teams need is narrower than the platform your office bought. The signals are listed in when you outgrow field service software.
Yes. You receive the complete source code, design files and documentation, and the store accounts stay in your company's name. There is no licence fee and no vendor lock in.
Delivery is closed by signing an acceptance protocol once the agreed scope works as specified. Anything in the fixed price scope that does not work is ours to fix, and larger contracts include a one year warranty on the software.
Walk us through how hours, photos and reports reach your office now. We will tell you what the first version should include, how long it takes, and what it would cost.
30 minutes, no preparation needed.
