為能真正上線的行動 MVP 定範圍

Most mobile MVPs fail on scope, not on technology. The feature list grows to match the website, the timeline triples, and the app never reaches a store. A shippable MVP starts by cutting almost everything.

One job, done well

The MVP does the single highest-value thing the customer needs on a phone: reorder, book, check status, capture data in the field. Everything else is a phase-two list, written down so stakeholders can see it is heard but not built yet.

One codebase, two stores

Flutter ships to Android and iOS from one codebase, which roughly halves build and maintenance cost against native pairs. Native still wins for hardware-heavy or platform-specific work — but most business MVPs are forms, lists, auth and notifications, where Flutter is comfortably enough.

Plan submission from week one

Store review rejects apps for predictable reasons: placeholder content, broken links, missing privacy policy, permission requests without explanation. Collect the assets early — screenshots, descriptions, data-safety declarations — so review is a step, not a surprise.

Instrument before launch

Crash reporting, basic analytics and a feedback path ship in version one. An MVP nobody measures teaches nothing; the point of shipping small is learning fast.
