Mobile App Development
iOS and Android. One codebase.
Cross-platform mobile apps built to scale — real-time features, push notifications, payments, and AI — shipped in weeks, not quarters. For businesses that need a branded mobile experience without two separate engineering budgets.

Spec through submission.
Product spec & UX flows
Written requirements, screen-by-screen user flows, and data model agreement before any code is committed.
Expo (React Native)
One codebase targeting iOS and Android simultaneously. Full access to native device APIs — camera, push, location, biometrics.
Real-time features
Live status updates, in-app messaging, worker tracking, and event-driven UI via Pusher. Built for the features that require it from the start.
Stripe Connect payments
Accept payments from customers, manage payouts to service providers or partners. Full payment lifecycle built into the app.
Push notifications
Expo Push Notifications wired to your business events — job updates, payment confirmations, reminders, and custom triggers.
AI-native features
Claude SDK integration for intelligent dispatch, content generation, routing decisions, or any business logic that benefits from AI.
Purpose-built backend API
Hono + PostgreSQL API built specifically for the app — not a generic backend bolted on. Architected around your data model.
QA and testing suite
Vitest unit tests, Playwright E2E, device testing across iOS and Android. Every critical path covered before submission.
App Store submission support
App Store and Play Store submission requirements, screenshots, metadata, privacy policy, and review process management.
Available capabilities

How we engage
Spec to App Store in five stages.
Product Spec
Written requirements: user roles, screen inventory, data model, third-party integrations, and edge cases. Everything is agreed upon before design begins.
UX Design
Screen wireframes, navigation flows, and interaction patterns reviewed and approved. You know exactly what you are building before it is built.
Build
Backend API and mobile app built in parallel by dedicated agents. ATHENA coordinates so integrations are never a surprise at the end.
QA & Device Testing
Full test suite run against the actual app. Testing on physical iOS and Android devices. Edge cases, error states, and performance under load.
Submit & Ship
App Store and Play Store submission support from end to end. We manage the review process and handle any rejections. Post-launch monitoring included.
Who this is for
Four types of mobile product.
Service marketplace platforms
On-demand dispatching, worker tracking, customer booking, payment collection, and review systems — a complete operational layer for on-demand service businesses.
Field service & inspection apps
Technician apps for job management, checklists, photo documentation, customer signatures, and back-office reporting. Replace paper and email.
B2B operational tools
Internal apps for teams in the field — inventory, scheduling, work orders, route planning, and real-time communication with office staff.
Consumer booking & loyalty
Customer-facing apps for appointment scheduling, membership management, loyalty programs, and personalized recommendations powered by AI.
Common questions
Straight answers.
Why Expo instead of native Swift or Kotlin?
One codebase, two platforms. Expo gives you full access to every native device API — camera, push notifications, location, biometrics, Bluetooth — at approximately 40% of the cost and timeline of two separate native builds. The performance difference for 99% of business apps is imperceptible to users.
What backend does the app connect to?
We build a dedicated Hono + PostgreSQL backend specifically architected for your app — not a generic backend dropped in. The data model, API routes, and business logic are designed around your specific workflows from day one.
Can we add features after launch?
Yes. We can continue on a monthly retainer for feature iteration, AI improvements, and platform updates. Expo makes over-the-air updates possible for most feature changes without requiring a full App Store resubmission — which keeps the iteration cycle fast.
What does App Store submission actually involve?
We handle the technical requirements: build configuration, App Store screenshots, metadata, privacy policy, required declarations, and the submission itself. Apple review typically takes 24–72 hours. We manage any rejection feedback and handle resubmissions. You do not need to deal with this directly.
Why mobile
Your customers are already on their phones.
Over 60% of web traffic in the Dallas-Fort Worth area comes from mobile devices. For service businesses — auto repair, home services, healthcare, fitness — that number is even higher. Your customers are searching, booking, and paying from their phones. If your business relies on phone calls and a website that was not designed for mobile interaction, you are losing leads to competitors who have a native app experience.
A mobile app is not just a smaller version of your website. It is a direct channel to your customer that lives on their home screen. Push notifications replace email marketing. In-app messaging replaces phone tag. Real-time tracking replaces "where is my technician" calls. Stripe payments replace paper invoices. Every interaction becomes faster, more reliable, and easier to track. For businesses that dispatch workers, manage bookings, or serve recurring customers, a mobile app is the single highest-impact technology investment available.
Routiine builds cross-platform apps with Expo and React Native, which means one codebase ships to both iOS and Android simultaneously. This cuts development cost by roughly 40% compared to building two separate native apps, while maintaining access to every native device feature — camera, GPS, biometrics, push notifications, and offline storage. The backend is a dedicated Hono and PostgreSQL API architected specifically for your data model, not a generic backend service bolted onto a template. Every app we ship goes through ten quality gates including automated testing, security review, and device testing on physical hardware before App Store submission.
Cost transparency
What to expect on budget and timeline.
Mobile app development costs vary widely depending on the number of user roles, the complexity of the backend logic, and whether the app requires real-time features like GPS tracking or in-app messaging. A straightforward service booking app with payments and push notifications typically falls in the $15K to $35K range and ships in 6 to 10 weeks. A full marketplace platform with dispatch, multi-party payments, real-time tracking, and an admin portal typically falls in the $40K to $80K range and ships in 10 to 16 weeks. We provide an exact quote after the product spec is finalized — there are no estimates that balloon during development.
The Expo and React Native stack we use cuts development cost by approximately 40% compared to building separate native iOS and Android applications. Both platforms share a single codebase, which means every feature, bug fix, and update ships to both app stores simultaneously. Over-the-air updates through Expo allow us to push most changes without requiring a full App Store resubmission, which keeps the post-launch iteration cycle fast and significantly reduces ongoing maintenance costs for Dallas businesses that need their app to evolve alongside their operations.
