FAQ
Can you build for both Android and iOS?
Yes. I use Flutter or React Native, so one codebase produces apps for both platforms. This costs roughly half of building two native apps and keeps future updates in sync across Android and iOS.
Should I choose Flutter or React Native?
Flutter suits apps with heavy custom UI and animation. React Native suits apps that share logic with a web product or need a large npm ecosystem. Tell me your project and I will recommend one with the reasoning, not just a preference.
Can you publish the app to the App Store and Google Play?
Yes, included in the Full App package and available as an extra on others. I handle store listings, screenshots, privacy details and the submission itself. You will need your own developer accounts, which I can help you set up.
How much do developer accounts cost?
Google Play is a one-time $25 fee. Apple charges $99 per year. These are paid directly to the platforms and stay in your name so you keep full ownership of your app listings.
Do I get the source code?
Yes, on every package. I push the full repository to your GitHub or send it as an archive, with a short walkthrough video covering the project structure and how to run a build yourself.
Can you integrate APIs, Firebase or a payment system?
Yes. I work with Firebase, Supabase, REST and GraphQL APIs, Stripe, and native in-app purchases. If you already have a backend I connect to it; if you do not, I can build one in Node.js or Python.
Can you build an MVP for my startup?
Yes, this is most of my work. I focus the first version on the core feature that proves your idea, ship it to the stores, then add features once you have real user feedback rather than building everything upfront.
Can you fix or update my existing app?
Yes. Send me the repository or store link and I will review it first. If the existing code is not worth continuing, I will tell you honestly and quote a rebuild rather than charging you to patch it.
Will I be able to see progress before delivery?
Yes. You get a testable build partway through, as an APK for Android or via TestFlight for iOS, so you can use the app on your own phone and give feedback while there is still time to change direction.
Can I order directly, or should I message first?
Either. If your project fits a package, order and I will start right away. If you are unsure about scope, message me and I will send a fixed price, timeline and feature list within the hour at no cost.
