Frequently Asked Questions about Web App Development
How much does it cost to develop a web app?
Cost varies greatly based on complexity, features and timeline. Simple apps: €3,000-8,000. Medium apps: €8,000-20,000. Complex apps: €20,000+. We offer a free consultation to quote your specific project.
How long does it take to develop a web app?
Depends on complexity. Simple app: 2-3 months. Medium app: 3-6 months. Complex app: 6-12 months. We work in 2-week sprints with incremental releases.
Can you integrate with legacy systems?
Yes, we integrate with legacy systems via APIs, SOAP, direct database connections. We handle data migration and integration testing.
Do you offer post-launch maintenance?
Yes, the first 30 days are included. We also offer monthly maintenance plans: monitoring, backups, security updates.
What performance and uptime guarantees do you offer?
We optimize for performance (load time <1s, targeting 99.9% uptime). We offer SLAs for support and monitoring. Load testing before deploy.
Can you develop mobile apps (iOS/Android)?
We develop Progressive Web Apps (PWA) that work on mobile like native apps. For native iOS/Android apps we recommend specialized partners.
