FAQ
Can you build one app for both Android and iOS?
Yes, I build cross-platform mobile apps with Flutter and React Native for Android and iOS from one codebase, saving time and budget with clean UI, smooth speed, and bug-free performance for all users.
Can you integrate ChatGPT or OpenAI into my app?
Absolutely. I integrate ChatGPT, OpenAI API, and custom AI chatbots into your Flutter or React Native app, with secure backends, fast replies, and smart features that keep users engaged and returning.
How long does mobile app development take?
A Flutter or React Native MVP usually takes 7 to 14 days, while full custom AI mobile apps take 3 to 6 weeks. Message me your ideas and I will send an exact timeline, plan, and quote for your project
Do you publish my app on Play Store and App Store?
Yes. I will handle Google Play Store and Apple App Store publishing, from developer account setup and screenshots to app review fixes, so your AI mobile app goes live quickly without rejection stress.
Can you build an app from just my idea?
Yes! Share your startup ideas, and I will plan features, design UI UX in Figma, build your Flutter or React Native app, test it, and deliver a launch-ready product that matches your goals and budgets.
Will I get the full source code?
Yes. You receive full source code, documentation, and app ownership after delivery. Your custom mobile app is yours completely, ready to scale, update, or hand over to any developer you pick later on.
Do you offer support after delivery?
Yes. Each order includes free post-delivery support for bug fixes and small tweaks. I also provide you ongoing app maintenance, upgrades, and AI feature updates so your Android and iOS app stays fast!
Which AI features can you add to my app?
I add AI chatbots, voice assistants, image recognition, smart recommendations, text generation, and machine learning predictions using OpenAI, TensorFlow, and Firebase, tailored to your app and users.
Can you fix or upgrade my existing mobile app?
Yes. I fix bugs, speed up app performance, redesign UI, and add AI features to your existing Flutter or React Native app. Send your code or app links and I will review it and give you an upgrade plan.
Is my app idea kept confidential?
Of course. I respect privacy and sign an NDA on request. Your app idea, code, data, and business details stay 100 percent confidential, and your AI mobile app is built securely from day one to launch.
