Mobile App Development Services

It depends heavily on what you're building. Simple MVP apps typically range from $30,000 to $60,000. Mid-complexity apps with custom backends, multiple integrations, and polished design run $60,000 to $150,000. Enterprise apps with complex workflows and security requirements can exceed $200,000. We provide detailed estimates after understanding your requirements—no ballpark numbers without context.

MVP apps typically take 8-12 weeks. Full-featured apps take 3-6 months. Complex enterprise applications can take 6-12 months. These timelines assume clear requirements and timely feedback. Scope creep is the biggest schedule killer—we plan carefully upfront to avoid surprises.

Cross-platform (React Native, Flutter) works well for most apps and saves 30-40% compared to building two native apps. We recommend native when you need maximum performance (games, AR, complex animations), heavy use of platform-specific features, or when your app is the core product for a funded company. For MVPs and most business apps, cross-platform delivers excellent results.

We sign NDAs before discussing project details. Our service agreement explicitly transfers all IP ownership to you—code, designs, documentation, everything. We implement secure development practices: access-controlled repositories, no code sharing between clients, and regular security audits.

Yes. Most apps need ongoing maintenance—OS updates break things, user feedback reveals improvements, and bugs surface in production. We offer maintenance retainers (typically 10-20% of initial build cost annually) or per-engagement support. No long-term lock-in required. For ongoing development and feature expansion, consider a Dedicated Development Team.

Our team works from Europe and Latin America—Portugal, Poland, Croatia, Ukraine, and Argentina. We've been remote-first since 2016, so timezone overlap and communication are solved problems. Most clients are in the US, and we maintain business-hours overlap for calls.

For iOS: Swift, SwiftUI, UIKit. For Android: Kotlin, Jetpack Compose. For cross-platform: React Native, Flutter. For backends: Node.js, Python, PostgreSQL, MongoDB. We deploy on AWS and GCP. Technology choices depend on your requirements and existing systems—we recommend based on what's right for your project.

We manage the entire submission process for both App Store and Google Play. This includes preparing screenshots, descriptions, privacy policies, and handling reviewer questions. Apple reviews are stricter—we build apps with guidelines in mind to avoid rejection. First-time approval rates for our apps are over 90%.

Absolutely. We do team augmentation where our developers integrate with your existing team, following your processes and tools. We also take on specific workstreams (mobile while you handle web) or provide specialized expertise that your team lacks.

We've shipped apps across fintech, healthcare, e-commerce, logistics, media, real estate, and education. Industry experience matters because each domain has its own regulations, user expectations, and integration requirements. Healthcare means HIPAA, fintech means PCI DSS—we've navigated these before.

Security is built in, not bolted on. We follow OWASP Mobile Security guidelines, implement secure authentication (biometrics, OAuth), encrypt data at rest and in transit, and conduct code reviews focused on security vulnerabilities. For sensitive apps, we engage third-party penetration testing before launch.

That's fine—most projects start there. We offer discovery workshops to turn your idea into a concrete plan: user stories, wireframes, technical architecture, and cost estimates. This phase typically takes 2-3 weeks. You get a clear roadmap before committing to full development. For early-stage validation, see our MVP development services.

Yes. We take over existing projects regularly—sometimes the original team disbanded, sometimes the codebase needs fresh eyes. We start with a code audit to understand what we're working with, identify technical debt, and plan improvements.

Weekly video calls for demos and planning. Daily availability on Slack for quick questions. Shared project board (Jira, Linear, or your preferred tool) for task tracking. Monthly written reports summarizing progress, spend, and upcoming work. You'll never wonder what's happening with your project.

We're not the cheapest or the biggest, but we ship. Senior developers working directly on your project, realistic timelines we actually hit, and architecture that doesn't need rebuilding in a year. Check our Clutch reviews—clients come back because we deliver.
