FAQ
What do you need from me to get started?
An app description (what it does and who it's for), a screen list or rough wireframes, any design files you have (Figma, screenshots, or reference apps), and backend/API details if you have an existing system. Don't have everything ready? Message me first — I'll help you figure out exactly what's ne
Do you build for both iOS and Android?
Yes. Flutter and React Native produce one codebase that runs natively on both iOS and Android. Every project I deliver works on both platforms unless you specifically request one only.
Can you work on my existing app instead of building from scratch?
Yes. I can add new screens, fix bugs, refactor messy code, or integrate APIs into your existing Flutter or React Native project. Share your codebase when you message me and I'll review it before we agree on scope and price.
Will I receive the full source code?
Always. 100% of the source code is delivered to you — clean, documented, and organized. You own it completely. I retain no rights to anything built for you.
Can you submit my app to the App Store and Google Play?
Yes — this is included in Standard and Premium packages, and available as an add-on for Basic. You'll need an active Apple Developer account ($99/year) and a Google Play account ($25 one-time). I handle the full submission process — screenshots, descriptions, and compliance. You just approve and pub
What if I don't have a design yet?
No problem. I'll implement a clean, modern UI based on your brief and reference apps you point me to. If you want a fully custom UI design before development starts, that's available as an add-on — message me and we'll scope it.
Can you add AI features like ChatGPT or recommendations to my app?
Yes. I've built OpenAI-powered features into production apps — including content moderation that reduced manual review time by 60%. I can integrate AI chat, GPT-4, voice features, image analysis, or recommendation engines into your Flutter / React Native app. Message me for a custom quote on AI work
Do you work with FlutterFlow?
I build custom Flutter apps from code, not FlutterFlow. However, if you have an existing FlutterFlow project that needs custom code extensions or a full migration to a native Flutter codebase, I can help with that — message me to discuss.
How do revisions work?
A revision is one round of consolidated feedback applied to the delivered work. Basic includes 2 rounds, Standard 3, and Premium 5. Revisions cover changes within the agreed scope — new screens or features outside the original brief are quoted separately. Additional revisions beyond your package
What happens after delivery?
All packages include 90 days of free bug support after delivery. If something breaks or behaves unexpectedly, I fix it at no charge. After that, I'm available for ongoing work and new features through a new order.
