Frequently asked questions

The process includes several phases: needs analysis, user interface design, development, testing, store deployment, and maintenance. Each step is validated with you to ensure alignment with your objectives.

I manage the entire publication process, from app creation to going live. I ensure your application complies with store guidelines, prepare all necessary elements (screenshots, descriptions), and handle any feedback from the validation teams.

I have a testing protocol where I review each feature on different devices and on older Android and iOS versions to ensure the app works for all types of users, guaranteeing an optimal experience for everyone.

I develop the interface so it automatically adapts to all screen formats. Each element is tested on different devices to ensure a beautiful presentation, whether on a small smartphone or a large tablet.

The methodology adapts to the scope of your project. For a simple app, I offer a direct approach with regular validation checkpoints. For more complex projects, I break down development into distinct phases, each with its own objectives and validations. This allows better control of costs and timelines while maintaining consistent quality.

I can integrate various usage aids depending on your needs: first-use tutorial, help tooltips on main features, introduction screens explaining key functionalities. These elements are always designed to be discreet and not bother experienced users.

Absolutely. I design applications in a modular way to facilitate future evolution. We can add new features, optimize existing ones, or adapt the app based on user feedback.

I ensure that older versions of the app continue to work and that user data is preserved during major updates.

New features are developed in isolation so as not to disrupt the existing app. A thorough testing phase is performed on the entire application to ensure new features integrate perfectly with existing ones. If optimizations are possible on existing features, I implement them as well to continuously improve the user experience.

I monitor announcements of new iOS and Android versions to anticipate necessary adaptations. The app is updated to take advantage of new features while maintaining compatibility with previous versions.

If you collect user feedback, we can plan evolutions to address their needs. These improvements are prioritized by importance and complexity, and can be integrated during regular app updates.

I offer a flexible payment schedule adapted to your project: 30% at signing to get started, then payments tied to key development milestones. The payment method used is bank transfer. For long-term projects, we can set up a monthly payment schedule.

No, all costs are transparent and detailed in the initial quote. This includes: development, testing, deployment, license fees if necessary, and store publication costs. Any maintenance or evolution costs are discussed with you based on your needs.

The annual maintenance budget typically represents 15-20% of the initial development cost. This covers: security updates, compatibility with new iOS/Android versions, bug fixes, and technical support. Customized packages are available based on your specific needs.

Yes, I offer a free, no-obligation initial consultation. After our discussion about your needs and objectives, you'll receive a detailed estimate within 72 hours including budget, timelines, and different options available for your project.

Play Store registration costs approximately 25 euros (one-time payment) and 99 euros per year for the App Store. These fees are included in the overall quote unless you already have your licenses. I handle the entire publication process. Regarding the preparation of required materials (screenshots, descriptions, etc.), it depends on your needs — your team can handle it or I can take care of it as well.

Yes, I offer several monthly maintenance packages: basic (fixes and updates), standard (+ technical support), and premium (+ feature evolutions). Each package is customizable based on your needs and user volume.

I maintain regular communication through weekly check-ins via video call or in person. You have access to a dashboard tracking project progress, and each major milestone includes a demonstration for validation. I also remain available by email or phone for any urgent questions.

Yes, it's possible after a technical audit phase of the existing code. This analysis evaluates code quality, identifies potential necessary improvements, and determines the best approach to continue development. I can then take over the project while maintaining existing features and making necessary improvements.

I use monitoring tools that allow me to detect if users encounter technical problems. The app is tested on the most common devices on the market, but given the wide variety of models available, adjustments may be needed after launch. Regular maintenance ensures compatibility with new devices and operating systems.

I perform several types of tests: functional tests to verify each feature works as expected, performance tests to ensure app smoothness, and tests on different devices to guarantee good compatibility.

I adapt to your existing ecosystem. I can work with your usual teams or providers, clearly defining each party's responsibilities. I provide the necessary technical specifications and ensure good communication to guarantee project consistency.

Data security is at the core of development. The app integrates: encryption of sensitive locally stored data, secure authentication with biometric option or other methods as needed, secure API communications (HTTPS/SSL), cache data protection, and secure data erasure upon logout.

Yes, the application is developed according to GDPR standards: minimization of collected data, explicit consent for permissions (location, notifications, etc.), ability to delete account and data.

I implement the most appropriate login methods for your needs: secure password, biometric login (fingerprint, facial recognition) if available on the device. The app can also integrate with your existing authentication system.

On screens containing sensitive information, I can implement screenshot protection. On both iOS and Android, the screen will appear black when a capture is attempted. I can also automatically blur sensitive information when the app goes to the background.

Data stored locally on the device is encrypted with industry-standard algorithms. Upon app uninstallation or logout, sensitive data is automatically securely erased. This ensures no information remains accessible even if the device is lost or stolen.

Yes, I offer post-launch support including corrective maintenance, security updates, performance optimization, and adding new features according to your needs.

Yes, I offer maintenance and optimization services for existing applications. After a thorough code analysis, I can identify and fix bugs, improve performance, and update the application to the latest standards.

I actively monitor new iOS and Android versions to anticipate necessary changes. Each major update is tested in a development environment to identify potential incompatibilities. I then offer preventive app updates to ensure continued compatibility and take advantage of new OS features.

For serious issues preventing app usage, I respond within 24 business hours. For minor issues that don't affect core functionality, intervention is performed within 48-72 hours.

If desired, I can integrate a feedback system directly into the app (contact form, bug reporting). These tools allow your users to easily report issues encountered. I can also set up crash monitoring to quickly detect and fix technical problems.

The choice depends on your goals. Native development offers the best performance and access to all platform-specific features. Cross-platform solutions are ideal for rapid deployment on both platforms with a tighter budget. I can advise on the best approach based on your needs.

I can develop your application with offline capabilities, allowing users to access essential content and synchronize data once the connection is restored.

I develop while ensuring compatibility with older versions of iOS and Android. The application is optimized to work efficiently even on less recent devices.

I can develop the application in a multilingual version, with automatic detection of the device language. The interface and content adapt according to the language chosen by the user.

iPhone and Android apps each have their own visual codes and interaction patterns. On iPhone, the interface follows Apple's guidelines with specific gestures and menus. On Android, the interface respects Google's standards. I develop respecting these specificities so users feel comfortable with the app, regardless of their usage habits.

Timelines are established after a detailed analysis of your needs. Each phase has specific objectives and deadlines: design, development, testing, deployment. The schedule is adjusted according to your priorities and constraints. Weekly checkpoints allow tracking progress.

I recommend regular updates every 1-2 months, an optimal frequency for maintaining good store visibility based on my experience. For bug fixes and security updates, deployment happens after resolution and Apple/Google validation — expect 24-72 hours for effective publication.

The timeline varies by complexity: 1-2 weeks for simple features, 3-4 weeks for medium features, 1-2 months for complex features. Each new feature follows a complete process: design, development, testing, and deployment.

The validation process typically takes 2-5 days on the Play Store and 1-3 days on the App Store. These timelines may vary depending on app complexity and review team workload.

The first submission requires a more thorough store review: complete content verification, rule compliance, detailed security analysis. Expect 5-7 days for the Play Store and 3-7 days for the App Store. This first validation is crucial as it establishes the app's initial compliance.
