Your App in Your Users' Pockets
Are you looking to create a high-quality mobile application?
To create a mobile application, we define the users, design, and functionalities that the product needs. We develop apps for iOS and Android with Flutter, sharing code and testing the experience on real devices.
We review native integrations, performance, and App Store and Google Play requirements. When browser access is sufficient, we also consider a PWA. The decision depends on the app's usage and the device capabilities it requires.
From Idea to App Stores
Our process to build your mobile app minimizes risk and speeds up deployment. From mobile app design to publication: early validation, fast iterations and a clear path.
-
Discovery and Definition
We analyze your model to define the best technology: Native app, hybrid (Flutter), or perhaps a PWA? We define critical functionalities for the MVP.
-
UX/UI Design
Wireframes and visual design adapted to iOS and Android guidelines to ensure smooth visual performance.
-
Iterative Development
Two-week sprints with builds of your hybrid app (Flutter) that you can install and test on your device.
-
Testing and Performance
Testing on physical devices, including low-end phones, automated testing, and thorough performance analysis before deployment.
-
Publication in Stores
We manage the complete deployment on Apple App Store and Google Play: accounts, assets, and publishing policies.
-
Maintenance and Evolution
App stores require constant updates. We offer ongoing maintenance to ensure performance with each new version of iOS and Android.
Why choose Mecexis to create your mobile app?
Experience with apps and PWAs used by thousands of people
We have built apps that handle millions of sessions a month and have scaled to hundreds of thousands of users without being rewritten.
A mobile app gets used on the metro, in an arena or on a phone that's a few years old, so we prepare it to respond just as well offline or on a modest device.
We also build the backend and manage the infrastructure, so performance issues are ours to solve. With hybrid technology (such as Flutter), a single codebase serves both iOS and Android.

Frequently Asked Questions
Clear answers to the most common questions about mobile application development.
Everything You Need to Know Before You Start
We cover both with a single development. We use hybrid technology (Flutter) that generates native code for both platforms from a single base.
It depends on the scope. A functional MVP typically costs between €25,000 and €50,000. More complex apps with a robust backend can exceed €100,000. We agree on the scope and give you a detailed quote after understanding your needs.
A typical MVP is in the app stores within 3-4 months. More complex apps can take 6-9 months. We work in two-week sprints with consistent releases.
Yes, we handle the entire deployment process on the App Store and Google Play, account management, assets, and regulatory compliance.
Yes. Every version goes through a test environment first, where your team installs it on their own devices and validates it before it's published on the App Store and Google Play.
Apps require ongoing maintenance. We offer maintenance contracts so your app keeps working with every iOS and Android update and meets the stores' new requirements.
If your system has an API or allows data export, yes. We integrate with ERPs, CRMs, payment gateways, and third-party services. If it doesn't have an API, we can develop a connection layer.
