First-submission store approval rate

Mobile app development services cover the full build of an iOS, Android, or cross-platform application: discovery, UX and UI design, front-end and back-end engineering, QA, security testing, app store submission, and post-launch support. In the United States, a production app typically costs $20,000 to $250,000 and takes three to nine months, depending on complexity, platform count, and compliance requirements.

Mobile App Development Services We Deliver

Most teams do not need every service on this list. A founder validating an idea needs an MVP and nothing else. An enterprise replacing a five-year-old app usually needs a consulting engagement, a modernization plan, and an integration audit before anyone writes code. AppVerticals offer a wide range of mobile app development services to match your exact business needs.

Custom Mobile App Development

Custom mobile app development means the app is built around how your business actually works instead of bending your operations to fit a template. It is the right call when your workflow is the product, when a SaaS tool covers 70% of what you need and the missing 30% is the part that matters, or when you need to own the code outright.

Key Benefits & Outcomes

  • Source code, design files, and IP transfer to you in full
  • Architecture chosen around your integration load and compliance obligations
  • A written product brief governs scope before development starts
  • Built to extend, so year-two features do not require a rewrite

Technologies & Process

Discovery produces a written product brief, an architecture recommendation, and a fixed-fee or time-and-materials estimate before anyone writes code. Stack is selected against your integrations and user roles, drawing on Swift, Kotlin, React Native, Flutter, Node.js, Python, and Go.

Not Sure Which Mobile App Development Services You Need?

Tell us what you are building and who it is for. Within 48 hours a US-based solution architect sends back a written recommendation covering scope, platform, stack, and an estimated cost band. No charge, and no obligation to work with us afterwards.

How much does it cost to build a mobile app?

A mobile app of medium complexity typically costs $50,000 to $120,000. Simple apps start around $25,000. Complex, regulated, or AI-driven builds run $120,000 and above. These are averages. There are apps that cost considerably less and apps that cost several times more, and we cannot price yours accurately until we understand your user roles, integrations, and compliance obligations.

Simple Medium Complex
What it is One core task, single user role, minimal backend Multi-step journeys, 2–3 roles, custom backend, integrations
Timeline 2–3 months 3–5 months
Typical cost $25,000 – $50,000 $50,000 – $120,000

Native or Cross-Platform: How to Choose

Choose native, meaning Swift for iOS and Kotlin for Android, when you need maximum performance, day-one support for new OS features, or deep hardware access. Choose cross-platform, meaning Flutter or React Native, when reaching both stores quickly and cheaply matters more than the last few percent of performance.

Factor Native Apps Cross-Platform Apps
Performance Best-in-class performance 90–95% of native performance for most app categories
Development Speed Slower development due to two separate codebases 35–45% faster development with a shared codebase
Total Cost (iOS + Android) $70,000 – $160,000 $45,000 – $95,000
Access to New OS Features Immediate access to the latest platform features Typically 3–6 month lag for new OS capabilities
Hardware and Sensor Access Full access to device hardware and sensors Full access through native modules when required
Maintenance Requires two codebases and separate skill sets One codebase managed by a single development team
Best Suited For Fintech, gaming, AR/VR, and enterprise applications requiring maximum performance MVPs, content platforms, e-commerce apps, and social applications

Mobile Apps We Build by Industry

Each industry has unique operational challenges, compliance requirements, and user expectations. A healthcare app and a booking app may share similar screens, but the systems behind them are built for completely different realities. Healthcare requires HIPAA controls, fintech depends on security and fraud prevention, logistics relies on offline reliability, and e-commerce succeeds on frictionless transactions. We build custom mobile app development solutions tailored to the workflows, regulations, and business goals that define each industry.

Our healthcare app development services focus on compliance, secure data handling, and improving patient access to care. Healthcare apps are governed by what happens to sensitive health data after it leaves the device. PHI must be encrypted at rest and in transit, every access event needs to be tracked, and third-party vendors must meet compliance requirements.

We build healthcare solutions including:

  • Telemedicine apps for virtual consultations
  • Patient portals for appointments, records, and communication
  • Remote patient monitoring platforms
  • E-prescription and pharmacy solutions
  • Clinical workflow and hospital management apps
  • EHR integrations with systems like Epic and Cerner using HL7 and FHIR

For hospitals, private practices, and healthtech companies.

How We Build Mobile Apps

The choices that shape a mobile build, meaning scope, platform, and architecture, are made in the first few weeks and set most of what follows. Our process puts those decisions up front and closes every stage with a named deliverable you can review before the next one starts.

Discovery and Strategy (1–2 weeks)

We interview your stakeholders, map user personas, review three to five competitors, and pressure-test the scope against your budget. You receive a written Product Brief covering scope, success metrics, a recommended stack with the reasoning behind it, a timeline, and a fixed-fee or time-and-materials estimate.

UX Wireframing and Prototyping (2–3 weeks)

Low-fidelity wireframes for every screen, then a clickable prototype you can put in front of real users before a line of production code exists. Changing a flow here costs an afternoon. Changing it in month four costs a sprint.

UI Design and Design System (2–4 weeks)

We build a full design system, meaning components, typography, colour tokens, and motion specifications, then apply it across every screen in light and dark mode. All design files transfer to you. Deliverable: design system and high-fidelity screens.

Front-End Development (6–16 weeks)

Engineers build in Swift, Kotlin, React Native, or Flutter, working in two-week sprints. Each sprint closes with a demo of working software on a real device, not a status update.

Back-End Development (parallel, 4–12 weeks)

Backend runs alongside the front-end rather than after it, using Node.js, Python, or Go on AWS, Azure, or Google Cloud. APIs are documented in OpenAPI and infrastructure is defined in Terraform, so nothing about your environment lives only in someone's head.

QA, Security and Compliance Testing (2–4 weeks)

Manual QA on physical devices, automated UI regression, load testing, an OWASP MASVS security scan, and a pre-submission audit against current store guidelines. Regulated apps get an additional compliance review.

Launch and Post-Launch (ongoing)

We handle App Store and Google Play submission and answer reviewer questions directly. For the first 30 days we monitor Crashlytics and Sentry and ship bug-fix releases at no charge. Handover includes the repository, deployment configuration, environment documentation, and architecture decision records.

Three Ways to Hire Mobile App Developers

Hiring mobile app developers usually comes down to one of two problems: you have no engineering team, or you have one that is short-handed against a deadline. Those need different answers. We run three models, and all three staff from the same pool of senior engineers with five or more years of production experience.

Model Best for What you get Pricing and minimum term
Full-Service Development Team Founders and companies without in-house engineering A complete mobile app development team: product manager, designers, engineers, and QA, managed end to end. You approve at each stage, and the team handles everything between. Fixed-fee or milestone-based · $25,000 – $120,000 / month · Project-based term
Staff Augmentation Teams with a specific skills gap or a deadline problem Hire individual mobile app developers who work inside your Slack, Jira, and repositories under your tech lead. iOS, Android, React Native, Flutter, or backend developers can be added to your existing team. Monthly per engineer · $8,000 – $25,000 · 3-month minimum
Dedicated Development Team Long-term products with a continuing roadmap Hire an app development team of five to fifteen people working dedicatedly on your product, with a named tech lead. The same team works month to month, so nobody has to re-learn your codebase. Monthly team rate · $40,000 – $180,000 · 6-month minimum

Trusted by enterprise teams globally

Our Mobile Technology Stack

We choose stack on the shape of the problem rather than on preference. Take a look at our widespread tech stack and see how we make sure every product is built using the right technology.

We choose the platform based on your users, performance requirements, and product roadmap. Native development with Swift and Kotlin gives maximum control for apps where speed and device-level capabilities matter, while Flutter and React Native help teams launch iOS and Android experiences from a shared codebase.

Choosing a Mobile App Development Company

The right app development partner brings more than coding expertise. Look for a team with proven product experience, a transparent process, clear ownership terms, and the technical depth to build and scale your app. Here’s what makes AppVerticals the first choice for businesses with the goal to scale.

Senior-only engineering teams

Every developer on your project has five or more years of production experience, and a US-based solution architect leads the engagement. The people who scope the project are the people who ship it.

Delivery speed without a quality trade

Production-ready MVPs in eight to twelve weeks, roughly 30% to 50% faster than traditional agency timelines, achieved through parallel design and development tracks and pre-built component libraries rather than by cutting review stages.

Pricing agreed in writing first

A written Product Brief and a fixed-fee or milestone quote before any code is written. Scope changes get priced and approved rather than appearing on an invoice.

Security and compliance from day one

ISO 27001 and SOC 2 Type II certified, with HIPAA, PCI-DSS, and GDPR requirements designed into the architecture rather than retrofitted before launch. OWASP MASVS testing on every build.

A 96% first-submission approval rate

Our pre-submission audit tracks every Apple and Google guideline change. When a submission does come back with questions, we handle the reviewer correspondence and resubmit at no charge.

Proof you can verify independently
