Turnaround inspection app
During a plant turnaround, inspectors scan the QR tag on each valve or vessel, work through an offline checklist, mark defects on photos and hand findings to the maintenance system once they are back in range.

Mobile App Development in Houston
Most of our mobile app development in Houston is for people who never sit at a desk, such as plant inspectors, site supervisors and drivers working out of the port. We plan for dead zones and storm outages before we design a single screen.

Apps for crews who work outside in Houston
Houston’s economy puts a lot of people in the field. Refineries and chemical plants line the Ship Channel, the Port of Houston keeps trucks and yards busy, and builders keep adding subdivisions across Harris County and beyond. The people doing that work open an app in a hard hat, in the heat, often with gloves on and one bar of signal. Big buttons, short forms and good photo capture matter more to them than a polished dashboard.
Weather is the other Houston constraint. Hurricanes and flash floods can knock out power and cell service for days, and that is when restoration, roofing and utility contractors are busiest. We build these apps offline-first, queue every photo and form on the device, and test sync by cutting the network mid-upload. For clinics in and around the Texas Medical Center the first constraint is different. Patient privacy gets designed in before the interface.
Typical mobile app development projects in Houston
Storm restoration dispatch
After a hurricane or flood, a restoration or roofing company assigns jobs, records damage with photos for insurance claims, and tracks crews in neighborhoods where cell service can stay patchy for days.
Specialty clinic patient app
Appointment requests, pre-visit forms, prep instructions and secure messages for a specialty practice whose patients travel in from across Texas and beyond for surgery or ongoing treatment.
Budgeting a Houston field or patient app
Each package is fixed-price for the agreed scope. Work outside that scope, or support after launch, is billed at $25–50 per hour.
| Package | Proof of concept | MVP | Market ready | Enterprise |
|---|---|---|---|---|
| Price | From $2,400 | From $9,600 | From $24,000 | From $48,000 |
| Typical timeline | 2–4 weeks | 2–4 months | 4–7 months | 7+ months |
| Usually, for Houston teams | One offline inspection checklist on a tablet, tested by a crew on a real unit | Field or driver app in both stores with photo capture, sync and an office dashboard | Bilingual app with QR asset tracking, a maintenance system integration and a storm-proof offline queue | Multi-site platform for plants or clinics with MDM rollout, SSO and several integrations |

Collaboration
Working with Houston teams
Our engineers keep U.S. business hours, so your superintendent or operations lead can reach us in the same workday when something on site does not behave. Before release we put the app in the hands of a few real crew members, watch them use it in the field and fix whatever they trip over.
Our U.S. operations are facilitated through Orcatec LLC, our trusted American business partner, enabling seamless collaboration with clients across the United States.

Frequently asked questions
Can an inspection app replace our paper checklists at a refinery or chemical plant?
Yes, and we usually start from your existing forms. Each checklist becomes an offline form with QR or barcode scanning for equipment tags and photo markup for defects, and results go to your maintenance system. If your site restricts phones in certain areas, we build for the devices your safety team approves.
What happens to the app during a hurricane or a long outage?
An offline-first app keeps working on the phone with no network. Jobs, forms and photos queue on the device and upload in order, without duplicates, when a connection returns. We size local storage for several days of photos and test with the network switched off, since that is what Houston crews deal with after a storm.
Do you build apps for practices in the Texas Medical Center area?
We build patient and scheduling apps designed for HIPAA: encryption, role-based access, audit logs and HIPAA-eligible hosting under a business associate agreement. We follow your compliance team on policy and do not certify compliance ourselves. EHR integration depends on the APIs your vendor offers, which we check during discovery.
Can a driver app for port drayage connect to our TMS?
If your TMS has an API or a regular data export, yes. Drivers see assigned containers and appointments, capture photos and documents at pickup and delivery, and send status updates that land in the TMS without retyping. We confirm what your system allows during discovery and include the integration in the fixed scope.
What does a field or inspection app cost for a Houston company?
Offline sync, the number of forms, scanning and integrations with maintenance or dispatch systems drive most of the cost. Packages start at $2,400 for a proof of concept, $9,600 for an MVP, $24,000 for a market-ready app and $48,000 for an enterprise rollout, all fixed-price. Changes outside scope run $25–50 per hour.
