Why do app development costs vary so much?

Cost depends on the number of features and screens, platforms, integrations, security requirements and design quality, as well as the team's location and seniority. Two apps that look similar can differ greatly in backend complexity.

Is it cheaper to build one app for iOS and Android?

Usually yes. Cross-platform frameworks like Flutter and React Native build both apps from a single codebase, which reduces development and maintenance cost compared with two separate native apps.

Is offshore app development safe for US startups?

It can be, with the right safeguards: a clear contract with IP assignment, code in your own repository, regular demos, defined communication hours and a team with a verifiable portfolio.

What ongoing costs should I budget for after launch?

Plan for hosting, third-party APIs, app store fees and commissions, updates for new operating system versions, security patches, monitoring and support. These continue for as long as the app is live.

How Much Does It Cost to Build an App in the USA in 2026?

The cost of building a mobile app for the US market depends mainly on complexity and on who builds it. Working with an offshore team like Mavani Solution, a simple MVP starts from $1,800, a mid-complexity app with payments, notifications and an admin panel typically costs $3,500 to $10,000, and a full-featured app costs $12,000 to $30,000. Our rates are typically 60% to 70% lower than US and European agencies for equivalent senior engineering, mainly because of local salaries and overheads. Whichever team you choose, the features, platforms and integrations you need decide most of the price.

Key Takeaways

Complexity, not platform, is the biggest cost driver: the number of screens, user roles, integrations and real-time features.
Cross-platform frameworks such as Flutter build iOS and Android from one codebase, which reduces build and maintenance cost.
Offshore teams can reduce cost substantially for US startups, provided communication, time-zone overlap and code ownership are agreed up front.
Budget for running costs: hosting, third-party services, app store fees, updates and support.
Start with an MVP that proves one core use case, then expand based on real usage.

App Development Cost by Complexity

These ranges are Mavani Solution's published prices for US clients:

Simple MVP, from $1,800. About 8 to 12 screens, sign-up, a core feature and a basic backend. Good for validating an idea with early users.
Mid-complexity app, $3,500 to $10,000. Payments, push notifications, user profiles, an admin panel and a few integrations.
Full-featured app, $12,000 to $30,000. Real-time features, multiple user roles, complex integrations, analytics and higher security requirements.

AI features such as recommendations, chat assistants or document scanning start from about $3,000 each. UI/UX design for a mobile app starts from $1,800. For an estimate based on your features, use our app cost calculator.

What Drives App Development Cost

Features and screens

Every screen needs design, development and testing. Features like chat, live tracking, video or offline sync take much longer than standard forms and lists.

Platforms

Building separate native iOS and Android apps roughly doubles the client-side work. Flutter or React Native deliver both from one codebase for most business apps. We compare the options in Flutter vs native development ROI.

Backend and integrations

Payments, maps, messaging, calendars, CRMs and other third-party services each add work. A custom backend with an admin dashboard is usually needed for anything beyond a simple app.

Security and compliance

Health apps handling patient data in the US need HIPAA-aware design, and fintech apps need secure payment handling and stronger authentication. These requirements add architecture, testing and documentation work.

Design quality

Clean, tested UX reduces support and improves retention. A design phase with a clickable prototype also reduces rework during development.

US Team vs Offshore Team

US-based agency or in-house team. Same time zone and easy in-person meetings, but much higher hourly rates, and in-house teams add recruiting, salaries and benefits.

Offshore team (for example, India). Lower cost for comparable engineering skill, and overlap hours can be arranged with US time zones. Success depends on clear written requirements, regular demos and shared tools.

Hybrid. A US-based product owner or fractional CTO with an offshore development team. This combines local product leadership with lower build cost. See when to hire a fractional CTO.

Running Costs After Launch

Hosting and backend services, which grow with users.
Third-party APIs: maps, messaging, payments, AI models.
App store fees: Apple's developer programme and Google Play registration, plus the stores' commission on in-app purchases and subscriptions. See Apple and Google billing rules.
Updates and maintenance for new OS versions, devices and security patches.
Support and monitoring, including crash reporting.

How Long App Development Takes

An MVP typically takes 12 to 16 weeks from discovery to App Store and Google Play submission. A full-featured app with real-time features, payments and an analytics dashboard typically takes 20 to 28 weeks. Timelines depend on how quickly decisions are made and on app store review. See our startup app development timeline guide.

How to Keep App Costs Under Control

Validate the idea with users before building; see how to validate a startup idea before building an MVP.
Limit the MVP to the core workflow.
Use cross-platform development where it fits.
Use managed services for login, payments, notifications and analytics.
Get fixed-price quotes per phase with clear deliverables.
Make sure you own the code, accounts and documentation.

From Our Work

Our mobile projects span fintech, sports, wellness and real estate. ParrotPOS, a bill payment and cashback app, took 8 months to build with Flutter, Firebase and Node.js, and Yogwe, a personalised wellness app, took 7 months on the same stack. Both shipped to Android and iOS from a single codebase.
