Problems We Solve
Sound familiar?
We've fixed these problems before. Let's make sure your app doesn't repeat them.
Low user adoption
Slow performance and weak UX make users drop the app instead of coming back.
Slow feature rollout
Even small changes take weeks, making it hard to react to user feedback.
Costly maintenance
Legacy or poorly built apps that require constant fixes and rising support costs.
Unreliable in production
Crashes, bugs, and inconsistent behavior that hurt the users' trust instantly.

With 16+ years of experience and hundreds of shipped products, Stfalcon knows how to build mobile apps of any complexity, including solutions for logistics and transportation companies.
We build native iOS apps using Swift and Apple-native technologies, including Face ID, Apple Pay, and on-device machine learning.
Our team delivers Android apps with GPS tracking, real-time synchronization, secure integrations, and other complex features your business requires.

Let's talk through your ideas and map out the next steps in a short, no-pressure call.
Our Approach
How our mobile app development process works
We've built and rebuilt mobile apps for teams across multiple industries. Our approach stays the same: adapt to the project's needs and tailor every technical decision to the specific case.
Step 1
Understand your business goals
We start by understanding what the app needs to achieve. This helps avoid building features that don't add value.
Step 2
Shape requirements and scope
Together with your team, we define functionality, platforms (iOS, Android, or both), and priorities. You get a scope and a realistic plan.
Step 3
Choose the right technical approach
Based on your goals, we recommend native or cross-platform development, define the architecture, and plan integrations.
Step 4
Design for usability and conversion
We design mobile-first interfaces focused on speed and ease of use, from onboarding to key actions that drive engagement or conversions.
Step 5
Build, test, and integrate
Development runs in iterations with continuous testing. We integrate the app with backend systems, third-party services, and analytics.
Step 6
Launch and support growth
We handle app store releases, monitor stability, fix issues quickly, and support further development as your app grows.
Success Metrics
How we measure success in custom mobile app development

Questions teams ask before a mobile app project
How do I know whether I need a custom mobile app development or just modernize an existing one?
During a short consultation, we review your current mobile app, business goals, and technical constraints. Based on that, we'll recommend whether a rebuild, partial mobile app modernization, or targeted improvements make the most sense.How long does mobile app development take?
Timelines depend on the scope, platforms (iOS, Android, or cross-platform mobile development), and the complexity of features. MVP or small mobile app: 2–3 months. Mid-size mobile app: 3–5 months. Complex or enterprise mobile app: 5–8+ months. For mobile app modernization, partial rebuilds or UX improvements often take 1–3 months.Can you work with an app that already has users?
Yes. We regularly work on mobile apps used by thousands or millions of users. We can improve performance, redesign UX, or scale features without disruptions.Which platforms do you support for custom mobile applications development?
We build native iOS apps, native Android apps, and cross-platform mobile apps using Flutter or React Native.Can you handle complex features like real-time data or GPS?
Yes. We've built custom mobile applications with real-time synchronization, GPS tracking, booking flows, payments, and integrations that operate at national scale.What does a mobile app project cost?
Cost depends on scope, platforms, design complexity, and integrations. MVP mobile app — from $65,000. Mid-size mobile platform — $120,000–$150,000. Enterprise mobile ecosystem — $150,000+. We provide a detailed estimate after the discovery phase.What happens after the app is launched?
We don't disappear after release. We support app store publishing, monitor performance, fix issues, and help evolve the product as usage grows. Many clients continue working with us as a long-term mobile development partner.
