App 开发套餐：从想法到上架的完整移动产品交付

A one-time engagement that scopes, designs, builds, and submits a mobile app (iOS + Android) for booking / loyalty / portal / marketplace / operations use cases. Defaults to React Native + Expo so ~80% of code is shared cross-platform; native iOS / Android when business case justifies.

A SeoMata app package always starts with use-case validation (vs PWA / website improvement / Zapier workflow). Sometimes the honest answer is "you do not need an app" — we will say so before charging.

Build an app when: (1) customer behavior is mobile-first and your home-screen icon is its own marketing channel, (2) you need device features (camera / GPS / push / biometric / offline) that browsers cannot do reliably, (3) you have field operations (drivers / technicians / sales reps) who need a focused tool, (4) you have a marketplace / SaaS / loyalty business where the app is the product.

Do NOT build an app when: (1) a PWA would work fine + cost 30-50% less, (2) the use case is one-shot (you would not return weekly), (3) you have not validated the website / lead funnel yet — an app cannot fix upstream problems.

Pick the $14,999 MVP tier when you need to validate an idea — 5–8 screens, single core flow, iOS + Android via React Native. 6–10 weeks to first TestFlight + Play Console build.

Pick the $34,999 v1 tier when you have validated the idea + need 10–15 screens with multiple flows, CRM/scheduling integration, in-app messaging. 10–14 weeks to v1 launch.

Pick the $79,999 full v1 tier when you need native iOS + Android (not React Native), marketplace / multi-tenant / B2B SaaS scope, backend services, compliance (HIPAA / SOC 2). 16–22 weeks to v1 launch with dedicated PM + iOS + Android + backend leads.
