Native iOS
application development
in Houston

For Houston businesses, iOS app development with Toimi starts at $25,000 for an MVP and typically ranges from $40,000 to $100,000 for a full-featured app. Energy sector clients in the Westchase district and medical device companies near the Texas Medical Center often require specialized integrations — HIPAA compliance, real-time sensor data handling, or equipment monitoring — which can increase project scope. We provide a fixed-price quote after the discovery phase, so you know exactly what you're investing before development begins. Payment is milestone-based, with 30% upfront and the remainder split across delivery checkpoints.

Most Houston projects take 3 to 4 months from kickoff to App Store launch. Discovery and design require 3-4 weeks, development runs 8-10 weeks, and testing plus deployment take another 2 weeks. If your app serves the Galleria area retail market or connects to existing enterprise systems at the Houston Ship Channel logistics hub, we factor in extra time for third-party API integration and load testing. We provide a detailed Gantt chart during onboarding so your team can plan around launch dates.

We work extensively with Houston's core industries — oil and gas field service apps for companies in the Energy Corridor, telemedicine and patient engagement platforms for providers around the TMC, and logistics tracking tools for Port of Houston cargo operations. Each sector has unique requirements: energy apps need offline functionality for remote sites, healthcare apps require HIPAA compliance and EHR integration, and logistics apps demand real-time GPS and barcode scanning. Our team understands these Houston-specific technical demands.

Toimi specializes in native iOS development using Swift and SwiftUI, which delivers superior performance and full access to Apple's latest frameworks — critical for apps using HealthKit for medical applications or ARKit for industrial training modules. Native apps load faster, handle complex animations smoothly, and integrate seamlessly with iCloud, Apple Pay, and Face ID. For Houston clients who need both iOS and Android, we can discuss React Native, but we recommend native development when user experience and device-specific features are priorities. Native code also simplifies compliance audits for healthcare and finance apps common in Houston's business landscape.

Given Houston's massive healthcare sector, we implement HIPAA-compliant architecture from day one — encrypted data storage using AES-256, secure API communication over TLS 1.3, audit logging for every data access event, and role-based permissions. We sign Business Associate Agreements before handling any PHI, conduct security reviews at each sprint, and provide documentation for your compliance team. Our backend infrastructure uses AWS HIPAA-eligible services with servers in US regions.

Absolutely — many Houston enterprises operate legacy ERP systems, proprietary databases, or industry-specific platforms that need mobile access. We build secure REST or GraphQL APIs to connect your iOS app with SAP, Salesforce, Oracle systems, or custom .NET backends common in energy companies. For manufacturers in Greenspoint or distribution centers near IAH airport, we integrate with warehouse management systems and IoT sensors for real-time inventory tracking. We handle authentication via OAuth 2.0 or SAML, maintain data synchronization even with spotty connectivity, and stress-test integrations under load conditions typical of Houston's large-scale operations.

You'll have a dedicated project manager available during Houston business hours, with Slack or Teams for daily questions and scheduled video calls every Monday and Thursday to review progress. We operate from Eastern Europe but overlap with Central Time mornings, and we adjust sprint planning meetings to fit your calendar. You get access to our Jira board to track every task in real time, see designs in Figma as we create them, and test builds via TestFlight every two weeks. For Houston clients managing remote oil field crews or multi-location healthcare operations, we're experienced at asynchronous collaboration — detailed written updates, recorded demo videos, and clear documentation mean you never lose visibility into the project.

Toimi provides 30 days of post-launch support included in every project — bug fixes, performance monitoring, and App Store optimization guidance. After that, most Houston clients choose a monthly maintenance retainer ($2,000-$5,000) covering iOS updates, server maintenance, security patches, and feature iterations based on user feedback. We monitor crash reports through Firebase, track KPIs in your analytics dashboard, and respond to urgent issues within 4 hours. As your Houston user base grows — whether that's patients across Harris County or field technicians from Beaumont to Corpus Christi — we can scale infrastructure, add features, and ensure your app continues performing reliably under increased demand.
