FAQ
Do you develop apps for both iOS and Android?
Yes! I develop cross-platform mobile apps using Flutter or React Native, ensuring one app works seamlessly on both iOS and Android.
Can you integrate third-party APIs and payment gateways?
Absolutely ✅ I integrate APIs, payment systems, social logins, and custom features as per your requirements.
Will my app have a modern and responsive design?
Yes! I design user-friendly UI/UX that adapts to all screen sizes for a smooth experience.
Do you provide backend development for apps?
Yes. I work with Firebase, NodeJS, DotNet Core, MSSQL, and MongoDB to create secure and scalable backends.
Can you publish my app on the App Store and Google Play?
Yes, I provide end-to-end support including app deployment to Google Play Store and Apple App Store.
Do you provide support after delivery?
Yes. I offer post-launch support, bug fixes, and maintenance plans to keep your app updated and secure.
Do you provide support and maintenance after the app is delivered?
Yes! I provide [14/30] days of free bug-fixing support after the final delivery to ensure everything runs perfectly. For long-term ongoing maintenance, regular updates, or adding new features, we can easily set up a custom monthly package or a separate gig.
What happens when iOS or Android releases a new system update?
Because I use modern, robust frameworks like React Native and Flutter, your app will be highly resilient to standard OS updates. If a major core update ever requires code adjustments in the future, I offer dedicated maintenance schedules to update your app and keep it 100% compatible.
Do you handle server and database maintenance after the app goes live?
I set up your backend architecture (NodeJS, Firebase, SQL, etc.) and hand over full ownership to you upon completion. If you prefer a hands-off approach, I offer ongoing server maintenance, database monitoring, and security updates as an optional monthly service.
