How Much Does It Cost to Build a Mobile App?

The cost to build a mobile app is the price of the scope you actually ship — platforms, surfaces, payments, and how many roles the product has — not a single catalogue number. Sigi Technologies does not publish client invoices or invented project totals. The ranges below are labelled typical-scope estimates for planning conversations. Real quotes come from a written brief. Sigi’s mobile work includes Flutter apps (3DLogistiX, Antrak, Bix, Trim) and React Native apps (Kwik eMart).

Recognized & reviewed on

A mobile app’s cost is driven by how many user types it serves, whether iOS and Android ship from one codebase, and what must be true in production (payments, maps, store review, admin). Sigi prices from that brief on mobile app development. This page does not invent what any named client paid. Published third-party prices that already appear in Sigi case studies (for example 3DLogistiX SaaS tiers, or off-the-shelf laundry SaaS ballparks) are product prices, not Sigi build fees.

Typical-scope estimates (not quotes)

These USD ranges are planning estimates for a custom build by a professional team in 2026. They assume product design, engineering, and basic QA — not a no-code template and not a Fortune-500 compliance programme. Currency, region, and seniority move the number. Treat them as order-of-magnitude, then ask for a scoped estimate.

$40k–$80k

Estimate: focused MVP, one codebase, core flows only

$80k–$180k

Estimate: production iOS + Android, auth, payments, admin light

$150k–$350k+

Estimate: multi-surface marketplace (customer + worker + admin)

What actually moves the price

  • Surfaces: one consumer app versus customer + driver/agent + admin (Just Dry Cleans, ServiPR, Kwik eMart, Antrak).
  • Shared record complexity: a booking calendar (Trim, ServiPR) versus an order state machine with proof of delivery (Just Dry Cleans, Kwik eMart) versus rack-and-bin inventory plus live 3D (3DLogistiX).
  • Money: Stripe checkout only versus per-provider connected accounts (ServiPR) versus charge-then-invoice adjustment (Just Dry Cleans).
  • Realtime: maps, job feeds, WebSockets (Antrak, 3DLogistiX, Kwik eMart tracking).
  • Store and release: two apps × two stores is four listings, as on ServiPR and Trim. Sigi handled those submissions on the named projects; budget time for review.
  • Staffing model: 3DLogistiX was engineering capacity inside an existing product team; other apps were end-to-end Sigi builds. Those are different commercials.

Which shipped Sigi apps sit in which complexity band

Use these as shape, not as prices. A scanning companion beside a web WMS (3DLogistiX Mobile) is a different brief from a four-surface grocery marketplace (Kwik eMart) or a bilingual two-app services marketplace (ServiPR). Trim shipped Flutter customer and business apps plus a React admin. Antrak shipped Flutter customer and driver apps with a Node.js dispatch backend. Just Dry Cleans added invoice-after-inspection and dual proof of delivery. Each extra surface and money rule is why the top estimate band exists.

Ways teams cut cost without inventing a bargain

  • One cross-platform codebase (Flutter or React Native) when the UI can be shared — see the companion comparison guide.
  • Ship customer value on one platform first only if the second store can wait; many of Sigi’s on-demand products needed both stores at launch because drivers and customers arrive together.
  • Reuse a proven order or booking model instead of a novel workflow on day one.
  • Keep v1 admin internal and ugly-but-correct rather than a second consumer-grade product.

Questions this guide answers

No. Price follows scope: surfaces, platforms, payments, realtime, and compliance. Sigi publishes typical-scope estimate bands on this page and quotes from a written brief. This page does not list what any named client paid.

A marketplace is several apps and one money model. Sigi’s Kwik eMart, ServiPR, Just Dry Cleans, and Antrak each shipped customer and worker surfaces plus admin. That is a different product than a single consumer app talking to an existing API.

One shared codebase usually costs less than two native teams for the same screens. It does not remove backend, design, QA, or store work. Sigi has shipped both Flutter and React Native; choose from product constraints, not from a discount slogan.

From the brief: who the users are, which surfaces launch together, which payments and maps are required, and whether Sigi is building end to end or extending a team. Contact Sigi via the mobile apps service page after reading the estimate bands above.
