Mobile App Development Company in Houston

We scope and quote each build rather than publishing bands. A scoped Houston mobile MVP is a ten to eighteen week engagement covering one platform (iOS or Android), offline sync, and the first integration (Epic Haiku, PI System mobile gateway, or a field operations backend). A production cross-platform energy field or clinical mobile app adds hazardous-area device validation, a HIPAA BAA, TDPSA disclosures, and App Store and Google Play release. Enterprise rollouts add MDM (Intune, Workspace ONE, Jamf), ITAR segregation, or CUBI-aligned biometrics. Houston sits below the Bay Area and New York but above secondary US markets because of the energy and TMC talent premium.

Yes. We target Class I Div 1 and Div 2 certified hardware (Aegex 10 tablets, Bartec Agile X IS, ecom Tab-Ex 03) for direct work in upstream offshore, midstream pipeline, and downstream refinery hazardous zones, and we validate the device-OS-app combination against the manufacturer’s intrinsic safety documentation before shipping. For supervisor-tier workflows that stay outside Division 1 zones, we use Samsung XCover Pro inside an intrinsically safe enclosure or rugged iPads with case-based attestation. Apps ship with offline-first sync (Realm or WatermelonDB), conflict-free updates when cellular returns, OSHA PSM-aware LOTO and JSA flows, and integration with PI System and asset frameworks where the operator runs AVEVA infrastructure.

Epic Haiku, Rover, and Canto sit inside Epic’s mobile suite and integrate with companion apps via Epic Bridges, FHIR R4 endpoints on App Orchard (now Vendor Services), and SMART on FHIR launch flows. We build companion mobile apps for MD Anderson, Memorial Hermann, Houston Methodist, CHI St. Luke’s, and Texas Children’s use cases like clinical photography for wound care, oncology consent capture, and ambulatory rounding aids that hand off cleanly into Haiku and Rover. PHI never lands on the device beyond an encrypted, MDM-controlled cache, and HIPAA BAAs are in place with every cloud service in the pipeline. HITRUST CSF readiness is delivered alongside the build.

Yes, with explicit scope. Mobile apps touching ITAR-controlled USML Category XV space-systems data require US-person engineer rosters, AWS GovCloud (US) or Azure Government backends, MDM with full attestation (Intune Government, Workspace ONE for FedRAMP environments), and CMMC 2.0 Level 2 or Level 3 readiness depending on the prime contract. Our delivery model separates unclassified product work (handled across Edmonton and Chandigarh hubs) from ITAR-bounded work (US-person only) and documents the segregation in the statement of work. We will not take an engagement where ITAR posture is not buildable on the timeline, and we will say so during discovery rather than after kickoff.

Texas Capture or Use of Biometric Identifier (CUBI) statute (Bus. & Com. Code § 503.001) governs facial recognition for clinical check-in at TMC, fingerprint-based field-worker authentication on offshore platforms, and biometric venue entry for Astros, Texans, and Rockets games. Our mobile builds capture informed consent with timestamped audit before any biometric is enrolled, store templates encrypted at rest and never transmitted in raw form, and run scheduled destruction jobs aligned with the one-year-after-purpose rule. Apple Face ID and Touch ID local-only flows where the template never leaves the Secure Enclave or TrustZone are preferred wherever the use case allows, because they reduce CUBI exposure substantially.

Yes. Offshore platforms in the Gulf of Mexico, the Permian, and Eagle Ford operate with intermittent VSAT, microwave, and 4G/5G coverage, so all energy field apps we build assume offline as the default and online as a periodic sync window. We use Realm, WatermelonDB, or SQLite with a CRDT layer for conflict-free updates, persist hours of operational data per device, batch uploads on connectivity return, and surface clear sync state to the field worker so safety-critical actions (LOTO, JSA, gas-detection logs) are never silently queued. Critical alerts use APNs and FCM with SMS fallback through Twilio for the period when satellite links are saturated.

A typical Houston field or clinical mobile app takes fourteen to twenty-two weeks from kickoff to App Store and Google Play release, assuming hazardous-area hardware decisions are settled by week 3 and Epic Bridges or PI Web API credentials are available by week 4. Week 1 to 4 is discovery, hardware selection, and integration credential sourcing. Week 5 to 14 is offline-first sync, the first integration, OSHA PSM or HIPAA workflows, and TDPSA disclosures. Week 15 to 18 is hardening, MDM integration, and store submission. Week 19 onward is pilot rollout with the first operator or TMC site. We have shipped to this cadence on Houston scope.

A typical Houston mobile pod is five to eight people: a US-based delivery lead in Central Time, one senior iOS engineer (Swift, SwiftUI), one senior Android engineer (Kotlin, Jetpack Compose) or a single React Native lead, one backend engineer for sync and integration, one platform/SRE for AWS or Azure, a part-time product designer, and a security lead for TDPSA, HIPAA, and CUBI work. For energy field engagements we add a hazardous-area hardware specialist who has commissioned Aegex or Bartec fleets before, and for Astros, Texans, and Rockets engagements we add a real-time and CDN specialist for in-venue and broadcast workflows.
