Mobile App Development
Your Idea, Turned Into an App Users Love
We design and develop native and cross-platform mobile apps for iOS and Android. From ideation to store publishing, with native performance, exceptional UX/UI design and ongoing support.
Your customers live on their phones, but your business isn't there
92% of mobile time is spent in apps, not web browsers. If your competitors have an app and you don't, you're ceding ground every day. But a poorly-made app is worse than none at all: 25% of apps are uninstalled after a single use.
Your customers access your service through the mobile browser with a slow, frustrating experience that causes immediate abandonment.
You can't send push notifications to re-engage inactive customers or communicate offers instantly like your competitors do.
Without offline access or native features (camera, GPS, biometrics), your digital service falls short of mobile user expectations.
Duplicated development budgets: maintaining separate iOS and Android apps multiplies costs and delivery timelines.
Everything Your App Needs to Succeed
We cover every aspect of mobile development: from designing the first screen to store publishing and data-driven iteration.
Native iOS & Android Development
We build high-performance native apps for both platforms, leveraging each operating system's full capabilities with Swift and Kotlin.
Cross-Platform Apps with Flutter & React Native
A single codebase for iOS and Android. We reduce development time by up to 40% without sacrificing performance or user experience.
Mobile UX/UI Design
Intuitive and visually striking interfaces, specifically designed for touch experiences on smartphones and tablets following Material Design and Human Interface guidelines.
Push Notifications & Engagement
Segmented push notification system, in-app messaging and retention strategies to keep your users active and boost engagement.
API & Cloud Backend Integration
Robust REST and GraphQL API connections, cloud databases with Firebase and AWS, secure authentication and real-time data synchronization.
App Store & Google Play Publishing
Complete publishing management: account creation, ASO-optimized listings, professional screenshots and approval process tracking.
In-App Monetization & Analytics
We implement monetization models (subscriptions, in-app purchases, freemium) and advanced analytics tools to measure and optimize your app's performance.
Automated Testing & QA
Thorough testing on real devices, automated testing with specialized frameworks and continuous quality control to ensure a bug-free app.

From Idea to App Store in 5 Steps
An agile and transparent process where you participate in every decision. Demos every two weeks so you can watch your app come to life.
Product Ideation & Validation
We analyze your idea, define the value proposition, study the market and validate the concept with potential users before writing a single line of code.
Product Ideation & Validation
We analyze your idea, define the value proposition, study the market and validate the concept with potential users before writing a single line of code.
Interface Design & Interactive Prototyping
We create wireframes, interactive Figma prototypes and pixel-perfect visual designs adapted to iOS and Android guidelines to validate the experience before development.
Development & Agile Sprints
We build your app using agile methodology in 2-week sprints. Functional partial deliveries from the first iteration so you can see real progress.
Testing on Real Devices
Thorough testing on physical iOS and Android devices, automated testing, performance testing and usability validation with real users.
Publishing, Launch & Iteration
We publish on App Store and Google Play with ASO-optimized listings. After launch, we iterate with real data: analytics, user feedback and continuous improvements.

The cost of developing a mobile app in Valencia depends on complexity and features. A basic app starts from €6,000, apps with advanced features (payment gateway, geolocation, chat) from €12,000, and complex platforms with robust backends from €20,000. We offer personalized quotes with no commitment.
For most projects, cross-platform development with React Native or Flutter offers the best balance: near-native performance, a single codebase for iOS and Android, and up to 40% lower costs. Native development with Swift/Kotlin is recommended when you need intensive hardware access or extreme performance (games, AR/VR).
A basic app is developed in 6-8 weeks, medium-complexity apps in 3-4 months, and complex platforms in 5-8 months. We work with agile methodology and deliver functional versions from the first weeks so you can validate with real users.
Yes. With cross-platform technologies like React Native and Flutter, we develop a single app that works natively on both platforms. We adapt the interface to each operating system's design guidelines so the experience feels natural on every device.
Yes, UX/UI design is an integral part of our process. We include user research, wireframes, interactive Figma prototypes, complete visual design and usability testing. We don't start coding until the design is validated.
Yes, we manage the entire App Store and Google Play publishing process: developer account creation, listing preparation with ASO (App Store Optimization), professional screenshots, optimized copy and review/approval process tracking.
Yes, we offer monthly maintenance plans including security updates, compatibility with new iOS/Android versions, bug fixes, crash monitoring and technical support. We also develop new features on demand.
Absolutely. We work in 2-week sprints with demos at the end of each one. You have access to test builds via TestFlight (iOS) and internal distribution (Android), plus direct communication with the development team through a dedicated channel.
