Frequently Asked Questions

Answers about mobile app development in Lithuania

Why does my business need a mobile app?

Mobile apps help you reach clients directly on their phones, ensure better engagement, loyalty, and faster access to services. Unlike a website, a mobile app can work offline, send push notifications, and create a personalized user experience.

What is the usual cost of mobile app development?

The standard hourly rate is 30 EUR/hour. Small projects start from 300 €, while more complex apps with integrations or backend systems usually range from 3,000–6,000 €. The price depends on functionality and project scope.

How long does it take to develop a mobile app?

A simple app usually takes about 1–2 weeks, while more complex projects (with database, payments, authentication) can take 1–2 months. The timeline always depends on the project size.

Do you develop both Android and iOS apps?

Yes, I develop apps for Android and iOS using Flutter. This allows writing code once for both platforms, making development faster and more cost-effective.

What is the mobile app development process?

The typical process consists of:
1. Consultation – discuss goals, requirements, and features.
2. Design – create UI/UX mockups and prototypes.
3. Development – implement features, database, and integrations.
4. Testing – quality, performance, and security tests.
5. Launch – publish the app on Google Play and App Store.
6. Support – updates, bug fixes, and adding new features.

Do you provide post-launch support?

Yes, I offer long-term support: app updates, bug fixes, new feature development, and integrations. This ensures your app remains reliable and secure as your business grows.
