FAQ
Frequently asked questions
It's building iOS and Android apps from a single codebase using React Native or Flutter, a native feel and performance without maintaining two separate apps, taking your product from MVP to store release.
Startups validating a mobile product, businesses extending a web product to phones, and teams who want one codebase across iOS and Android instead of paying to build and maintain two.
A store-ready MVP typically takes 8 to 16 weeks depending on features and integrations. You get test builds on your own phone from week one and TestFlight or Play Console betas before submission, so there are no surprises at launch.
A cross-platform app, backend and API integration (offline-first where it matters), push notifications, analytics and crash reporting, App Store and Play Store submission, and post-release updates and maintenance.
We choose based on your app's needs, not habit: React Native when you're already JavaScript and React heavy, Flutter for highly custom UI. We'll explain the trade-off for your specific case rather than defaulting to one.
