FAQ
Can you build both Android and iOS?
Yes. I can build Android and iOS versions with Flutter or React Native, or use FlutterFlow, Bubble, Adalo, or another suitable stack when it fits the product. Confirm your preferred technology before ordering.
Can you integrate payments or a crypto wallet?
Yes, I can integrate supported payment APIs and wallet-related flows. You must provide the chosen provider, approved credentials, documentation, and business rules. I do not bypass KYC, AML, security, or local regulations.
Will you publish the app to Google Play or the App Store?
I can prepare production builds and guide or assist with submission. You must own the developer accounts, provide required store information, and approve any compliance, privacy, or review responses.
What do you need before starting?
Send your app brief, user roles, screen list, brand assets, target platforms, preferred stack, API/payment documentation, and any reference apps. Clear requirements prevent delays and scope changes.
Does the package include the backend and admin panel?
The Basic package is a prototype. Backend, APIs, database, admin dashboard, and third-party services are included only when listed in the selected package or custom offer. Ask for a tailored quote if your product needs them.
Can you sign an NDA and provide maintenance?
Yes, I can review a reasonable NDA before the order. Maintenance, updates, security fixes, and new features can be arranged as a separate monthly or milestone-based service.
