FAQ
Will my app work on both iOS and Android?
Yes, I build cross-platform apps using React Native or Flutter for iOS & Android. However, these app stores requires some time for actual production deployments. So, you might need to wait 7-14 days to get the app approved.
Can you publish the app on the App Store and Google Play?
Yes! I handle app submission, testing, and deployment to both stores.
Can you integrate push notifications, maps, or payment gateways?
Absolutely! I can integrate Firebase, Google Maps, Stripe, PayPal, and more. Premium already includes these. But ping me to get total cost.
Will you provide source code and documentation?
Yes, you will get the full source code, setup instructions, and documentation. Usually I provide .md files for DeployGuide, UserGuide, ProjectStructure. However if you need I can also provide pdf for an extra fee.
Do you provide app maintenance and updates?
Yes! I offer post-launch maintenance & bug fixes (additional charges may apply). Premium offers included only once any amount of bug fix in the app I designed.
Do you use any AI tool for coding?
No, I understand some people do not like AI or sometimes AI causes performance issues or security risks. So, no AI tool is used for coding.
