The three questions every buyer asks — what will it cost, how long will it take, native or cross-platform? — are answered directly on this page: most business apps run $40K–$150K over 12–20 weeks, and for roughly 80% of business cases, cross-platform (Flutter or React Native) is the right call. The detail is below; the shortcut is a free app estimate.

We'll put our recommendation for your case in writing, with reasoning — and if native is overkill for your app, we'll say so even though it would bill more. Full analysis: Flutter vs React Native and native vs hybrid vs cross-platform.
**Product discovery (1–2 weeks).** Who is the user, what job does the app do, what's the retention hook? Output: feature map, user flows, fixed quote. Apps fail on definition more than on code — this phase exists to prevent that.
**UX/UI design.** Clickable prototype tested on real users before a line of production code. Store-ready visual design for both platforms' conventions.
**Sprint development.** Two-week sprints; TestFlight / Internal App Sharing builds on your phone from the first month. Backend and app built in parallel.
**QA on real devices.** Automated tests plus manual QA across a physical device matrix (not just simulators) — old Androids included, because your users have them.
**Store launch.** We prepare listings, screenshots, privacy declarations, and review submissions for both stores — and handle the rejection-response cycle if Apple pushes back. Average first-approval rate: [X%; replace with real figure or remove].
**Post-launch.** Crash monitoring, analytics review at day 7/30, and a prioritized v1.1 backlog from real usage data. The app you launch is the start, not the end.
Offline-tolerant architecture · push notifications done respectfully · analytics instrumented from day one (retention funnels, not vanity installs) · accessibility (WCAG-aligned) · app-store privacy compliance (ATT, data-safety forms) · CI/CD so updates ship in days, not release-crunch weekends.
Healthcare apps (HIPAA-compliant messaging, RPM) · FinTech apps (KYC, biometric auth, PCI scope) · Logistics (driver apps, proof-of-delivery) · Restaurants & food delivery · Fitness · Real estate · Field services · All industries →

Backend, admin dashboard, and both platforms are included in these ranges. What moves the number most: third-party integrations, real-time features, and compliance scope — itemized in the app development cost guide.
$30K–$60K for a simple app, $60K–$150K for a typical business app, $150K+ where payments, video, or regulated data are involved — including backend and both platforms. Your fixed quote comes from a 1–2 week discovery.
| Choose | When | Why |
|---|---|---|
Cross-platform (Flutter / React Native) | Business apps, marketplaces, field tools, most consumer apps | One codebase, one team, both stores; near-native performance for typical UI-driven apps |
Native (Swift + Kotlin) | Heavy hardware use (BLE, camera pipelines, AR), console-grade animation, platform-first features | Maximum performance and day-one access to new OS capabilities |
PWA | Internal tools, content apps, no-store-needed distribution | Fastest and cheapest to ship; no store review cycle |
| App complexity | Range | Examples |
|---|---|---|
| Simple (single core flow) | $30K – $60K | Booking app, content app, internal field tool |
| Standard business app | $60K – $150K | Marketplace, delivery app with tracking, patient app with messaging |
| Complex / regulated | $150K – $400K+ | FinTech with KYC + payments, telehealth with video + EHR integration |
