App Development

APP Development | iOS, Android & Flutter

Ship apps that can be listed and operated—not demos. Typical stacks are Flutter or native with admin backends, membership, and APIs; add AI, payments, or push when needed.

適合解決的問題

  • ・Have a product idea but lack a team that can build both APP and admin backend.
  • ・Existing Web / admin needs a membership APP or field operations APP.
  • ・Unsure whether to use Flutter cross-platform or separate iOS / Android.
  • ・Need store listing, push, login, and admin—not just UI mockups.

可以包含什麼

  • ・iOS / Android / Flutter cross-platform APPs
  • ・Membership, login, push, and permissions
  • ・Admin backend systems and APIs
  • ・Common integrations: payments, maps, camera
  • ・App Store / Google Play listing support
  • ・AI features when needed

怎麼做

  1. Requirements and platform

    Clarify users, feature priority, and whether Flutter or native is the better fit.

  2. APP + admin

    Design UI, APIs, and database together so the APP doesn’t ship disconnected from operations.

  3. Test and launch

    Accept in staging, support store listing, and keep an operations window.

適合誰、時間與費用

  • ・Startups or brands that need a customer-facing product APP
  • ・Field ops, membership rewards, points, or booking APPs
  • ・Enterprises with an admin backend that need a mobile interface

時程：Small MVPs commonly take 1.5–4 months; with admin, payments, and multiple roles usually longer. Store review time is separate.

費用：Scoped by number of platforms, admin scope, and third-party integrations. We assess requirements before quoting—no hard price without seeing scope.

正式價格於需求確認後提供，以上為參考。

我們不會直接承諾的事

  • ・Store review, payments, and third-party account setup time are not guaranteed.
  • ・No hard price when scope is undefined.
  • ・We don’t recommend “UI-only APPs” without an admin backend and data model.

常見問題

Flutter vs native iOS / Android?

For most commercial apps that need both platforms on a limited budget, Flutter is more efficient. Evaluate native when you need deep system capabilities, special hardware, or existing native codebases.

Can you build only the APP without an admin backend?

Yes, but most products still need an admin for members, content, or orders. During requirement analysis we’ll explain the minimum backend capabilities needed.

Can the APP connect to AI?

Yes. A common pattern is the APP calling your APIs, with the backend wiring OpenAI / Gemini and controlling keys, usage, and permissions on the server.
