FAQ
Why should you choose me?
We build polished mobile apps with React Native, Flutter, Swift, and Kotlin. Senior team only, no outsourcing. Apps shipped in fintech, edtech, food delivery, healthcare across EU and US.
iOS, Android, or both?
Both. We build cross platform apps with React Native or Flutter (one codebase for iOS and Android). Premium package includes separate native development with Swift for iOS and Kotlin for Android for maximum performance.
Do you handle App Store and Google Play submission?
Yes. Standard and Premium packages include full submission to both App Store and Google Play. We handle store listings, screenshots, descriptions, and review process. You need to provide developer accounts ($99 Apple, $25 Google).
Do you provide design or do I need to bring my own?
We provide custom UI/UX design in all packages. If you have your own Figma designs we follow them precisely. If not, our designers create polished, modern interfaces tailored to your brand and target audience.
What about backend and database?
Firebase backend is included in Standard and Premium packages (auth, database, storage, push). For custom backend with Node.js and PostgreSQL, that is part of Premium or available as a custom offer with our Web App gig.
Will I receive the source code?
Yes. All packages include full source code via GitHub. You own the code completely. Premium includes detailed documentation and code comments so any developer can continue working on your app.
Do you provide post launch support?
Premium includes 60 days of post launch support (bug fixes, minor updates, store rejection issues). Basic and Standard come with 14 days. Extended monthly support and feature updates are available as a custom retainer.
