Our Process

How do we move a mobile app from idea to App Store in 6 sprints?

A predictable, transparent mobile app development process that has shipped apps for service businesses, SaaS startups and enterprise clients for over 20 years.

STEP 01

Discovery & Strategy

Goals, target users, monetization, platform decision (iOS, Android, cross-platform or PWA) and a written technical scope.

STEP 02

UX & UI Design

User flows, wireframes and high-fidelity mockups in Figma. Mobile-first, accessibility-checked, brand-aligned screens for every state.

STEP 03

Backend & APIs

PHP / Node / Next.js APIs, MySQL or Postgres schema, auth (OAuth / JWT), payment integrations, push and SMS systems.

STEP 04

Mobile Build & AI Wiring

React Native, Flutter or native iOS / Android development. AI features wired with OpenAI, Anthropic, on-device models and vector search.

STEP 05

QA, Beta & Submission

TestFlight and Play Console beta with real users, full QA, accessibility, performance and security testing, then App Store + Play Store submission.

STEP 06

Launch & Growth

Analytics, ASO, A/B testing, push campaigns, crash monitoring and a roadmap of updates so the app keeps earning its place on the home screen.

FAQ

Mobile App Development Questions, Answered

Everything we get asked before kicking off a mobile app project.

How much does a custom mobile app cost?
A single-platform MVP starts at $24,000, a polished iOS + Android production app typically runs $65,000-$120,000, and enterprise multi-app systems with native iOS and Android plus field / driver companion apps start at $150,000. Final pricing is set after a free discovery call where we scope the feature list and platforms together.
How long does it take to build a mobile app?
MVPs ship in 4-8 weeks. Production iOS + Android apps typically take 10-16 weeks from kickoff to App Store. Enterprise apps with multiple roles, on-device AI and complex integrations usually run 4-6 months. We provide a sprint-by-sprint schedule before any code is written.
Should I build native iOS, native Android, or cross-platform?
If you need maximum performance, deep platform features (CarPlay, Apple Intelligence, Live Activities, Wear OS) or AAA-grade UI - go native. If you need to ship fast on both platforms with one codebase and the app is mostly business workflows, cross-platform (React Native or Flutter) is usually the right call. We help you pick during discovery.
Do I own the source code and app store accounts?
Yes. You own 100% of the source code and intellectual property. The apps are published under your own Apple Developer and Google Play accounts so you can transfer the app or change agencies at any time. We never lock your business into our platform.
Can you add AI features to my existing mobile app?
Yes. We routinely audit existing iOS / Android / React Native / Flutter apps and add RAG chat, vision pricing, on-device LLMs, voice agents, semantic search or generative features on top of the existing codebase. Many of our AI-feature projects start as add-ons to a working app.
Will my mobile app work offline?
Yes, when it makes sense. Field apps, driver apps and apps for users with spotty signal get offline-first architecture: local SQLite or Realm storage, queued writes, conflict resolution and background sync the moment connectivity returns. Many of our enterprise apps function fully offline for an entire shift.
Do you handle App Store and Google Play submission?
Yes. We prepare your App Store listing (icons, screenshots, descriptions, keywords for ASO), handle TestFlight beta, manage the App Review process, respond to reviewer questions and resubmit until approved. We do the same for Google Play and follow up on staged rollouts.
Do you provide ongoing support after launch?
Yes. Every plan includes 30-365 days of post-launch support. After that, most clients move to a monthly retainer that covers OS updates, bug fixes, ASO, analytics, A/B tests and a steady stream of new features so the app keeps earning its spot on the home screen.
Can you build companion apps for drivers, technicians or admins?
Yes - this is one of our specialties. Many of our clients run a customer-facing app plus a separate driver, technician or field-ops app and a web admin dashboard. We design them as one connected system with shared backend, real-time sync and role-based permissions.
Are you a Kansas City mobile app developer?
Yes. The Turn Group is based in Kansas City and we have been building mobile, web and software for KC businesses for over 20 years. We also serve clients nationwide and have shipped apps for clients in healthcare, aerospace, education, hospitality and home services across the United States.
