FAQs

Flutter or native—what do you recommend?

We default to Flutter for most products to ship faster across iOS & Android. We go fully native in Swift/Kotlin when heavy camera/Bluetooth, ultra-low latency, advanced background execution, or deep platform integrations are core to the experience.

Do you build the backend too?

Yes. We deliver a Node.js API with MongoDB (Atlas) and provide Postman collections, env templates, and deployment docs.

Can you integrate with our existing services?

Absolutely—REST or GraphQL, payments, auth providers, and 3rd-party APIs.
