Common Mobile App Development Challenges
Here's what we help businesses overcome.
You're unsure whether to build native iOS/Android or go cross-platform
We analyze your requirements and recommend the right approach. Cross-platform saves 30-40% when it fits.
Previous apps got rejected by the App Store or Play Store
90%+ first-time approval rate. We build with platform guidelines in mind from day one.
Your existing systems don't integrate well with mobile
API development connecting ERPs, CRMs, payment gateways, and legacy backends.
Security and compliance requirements keep you up at night
HIPAA security, PCI DSS features, GDPR protections built in. Encryption, secure auth, and audit trails from the start.
You've been burned by agencies that disappeared after launch
Ongoing maintenance included. OS updates, bug fixes, and performance monitoring.
You need to launch fast but can't sacrifice quality
Agile sprints with working builds every 2 weeks. Test early, iterate quickly.
Mobile App Development Services
End-to-end mobile development from strategy to launch, covering native iOS and Android, cross-platform solutions, and everything in between.
iOS App Development
We build native iOS applications using Swift and SwiftUI that feel right at home on iPhone and iPad. Our iOS developers have shipped apps across fintech, healthcare, and consumer markets—so we know what Apple reviewers look for and what users expect. Every app follows Human Interface Guidelines, uses modern frameworks, and gets optimized for performance on older devices too.
Android App Development
Native Android development using Kotlin and Jetpack Compose for smartphones, tablets, and specialized devices. We've dealt with the fragmentation headaches—different screen sizes, OS versions, manufacturer quirks—so your users don't have to. Our Android developers build apps that perform well on budget devices while taking advantage of flagship hardware.
Cross-Platform Development
React Native and Flutter development for apps that work on both iOS and Android from a single codebase. This isn't about cutting corners—it's about shipping faster without sacrificing quality. You get 30-40% cost savings compared to building two native apps, and your team maintains one codebase instead of two.
Backend & API Development
Your app needs a reliable backend—whether that's a straightforward REST API or a more complex system handling real-time data, authentication, and third-party integrations. We build backends using Node.js, Python, deploy on AWS or GCP, and set up proper CI/CD pipelines. We handle database design, API architecture, and authentication flows. For dedicated backend expertise, see our Backend Development Services.
UI/UX Design
Mobile design that works means understanding how people actually use their phones—thumb zones, interruptions, varying network conditions, accessibility needs. Our designers create interfaces that feel intuitive from the first tap. We run user research, build interactive prototypes, and test with real users before development starts.
App Maintenance & Support
Launching is just the beginning. iOS and Android release new OS versions every year, app store policies change, and bugs surface that you couldn't predict. We provide ongoing maintenance: performance monitoring, crash analytics, security patches, OS compatibility updates, and feature enhancements based on user feedback.

Platform choice
High impactBuilding for iOS only is cheaper than iOS + Android. Cross-platform saves 30-40% compared to two native apps, but native still wins for performance-critical apps.
Feature complexity
High impactA simple CRUD app costs less than one with real-time sync, video streaming, or complex algorithms. Features like chat, payments, or maps each add development time.
Backend requirements
Medium to High impactSome apps work with simple APIs, others need complex backends with user management, business logic, and integrations. If you have existing APIs, costs drop.
Third-party integrations
Variable impactPayment gateways, maps, social login, analytics—each integration has its own quirks. Well-documented APIs are quick. Legacy systems take longer.
Compliance requirements
Medium impactImplementing HIPAA, PCI DSS, GDPR requirements adds overhead for documentation, security measures, and audit trails. Budget 15-25% extra for regulated industries.

FaQ
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.
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.
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.
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.
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.
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.
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.
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.

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.
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.
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.
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%.
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.
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.
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.
