Mobile App Development Services — Hire an App Developer
Looking to build a mobile app? Whether you're a startup with a new idea, a business that needs a custom tool, or an individual with a concept you want to bring to life, finding the right developer is the most important decision you'll make. This guide covers what to expect when hiring an app developer — costs, timelines, process, and technology — and explains how SMTN Tech can help you build and launch your app.
How Much Does It Cost to Build an App?
App development costs depend on complexity, features, and platforms. Here's a realistic breakdown:
Simple Apps — $10,000–$30,000
Apps with a few screens, basic functionality, and no backend. Examples: calculators, simple informational apps, basic utility tools.
Mid-Complexity Apps — $30,000–$75,000
Apps with custom UI, user accounts, backend/database integration, push notifications, and API connections. Examples: scheduling apps, e-commerce apps, content platforms.
Complex Apps — $75,000–$150,000+
Apps with real-time features, complex business logic, advanced integrations, payment processing, or large-scale infrastructure. Examples: social networks, marketplace apps, fintech tools.
Save 30–40% with Cross-Platform Development
Using Flutter, we build one codebase that runs on both iOS and Android — instead of paying for two separate native apps. This significantly reduces cost and development time while delivering native-quality performance on both platforms.
How Long Does It Take to Build an App?
Timelines vary by scope, but here's what to expect:
- Simple apps: 2–3 months
- Mid-complexity apps: 3–5 months
- Complex apps: 6–9+ months
These timelines include the full process: discovery, design, development, testing, and App Store submission. We provide regular test builds so you can follow progress throughout.
Our Development Process
We follow a proven four-phase process that keeps you involved at every step:
- Discovery — We learn about your idea, define requirements, research your market, and plan the project scope and timeline.
- Design — We create wireframes and visual mockups so you can see and approve the look and feel before any code is written.
- Development — We build the app with regular check-ins, test builds, and progress updates so nothing is a surprise.
- Launch — Final testing, polish, App Store and Google Play submission, and post-launch support to make sure everything runs smoothly.

Why Flutter for App Development?
We specialize in Flutter, Google's open-source framework for building cross-platform mobile apps. Flutter lets us write a single codebase that compiles to native iOS and Android apps — delivering real native performance, not a web wrapper.
Benefits of Flutter development:
- One codebase, two platforms — Ship for iOS and Android simultaneously
- Native performance — Compiles to native ARM code, not interpreted
- Faster development — Hot reload, rich widget library, and mature ecosystem
- Lower cost — 30–40% less than building separate native apps
- Proven at scale — Used by Google, BMW, eBay, Toyota, and thousands of production apps

Freelancer vs. Agency vs. Small Studio
When hiring an app developer, you generally have three options:
- Freelance developer — Lower rates, flexible scheduling, but may lack design, backend, or deployment skills. You often need to manage the project yourself.
- Large agency — End-to-end service with multiple specialists, but significantly higher rates ($150–$300+/hr) and less direct access to the people building your app.
- Small studio (like SMTN Tech) — The best of both worlds: direct communication, competitive pricing, and full-service capability covering design, development, backend, and App Store launch.
We're a small, focused team that handles everything from concept to launch. You work directly with the people building your app — no account managers or layers of bureaucracy.
