Development Cost by App Complexity

**Simple app** (4–6 screens, basic CRUD, one user role): €8,000–15,000. Typical example: internal tool, simple directory, basic booking flow. Timeline: 2–3 weeks.

**Mid-complexity app** (8–12 screens, multiple user roles, payments, push notifications): €15,000–30,000. Typical example: marketplace MVP, SaaS mobile companion, booking platform. Timeline: 4–6 weeks.

**Complex app** (15+ screens, complex logic, AI features, real-time, custom integrations): €30,000–60,000. Typical example: full-featured SaaS mobile app, social platform, fintech app. Timeline: 8–12 weeks.

These are agency rates. A freelance FlutterFlow developer costs €400–800/day and takes longer β€” account for QA, project management, and deployment time that agencies include.

Tool Costs (Monthly)

FlutterFlow: $0 (free, limited) / $30 (basic) / $70 (pro) / $150 (teams). For production apps, you need at least the $70 Pro plan.

Supabase: $0 (free tier, great for MVPs) / $25/month (pro, required for production). Pro includes daily backups, no pausing, custom domains.

Xano (if used for backend logic): $59–135/month.

Firebase (if used instead of Supabase): Often free at MVP scale, but pricing scales unpredictably with users.

**Total tool cost for a production app**: €100–200/month covering FlutterFlow + Supabase + any third-party services (email, push notifications, payments).

App Store Costs

Apple Developer Program: $99/year (required to publish on iOS). One-time setup β€” includes TestFlight for beta testing.

Google Play Developer Account: $25 one-time fee (required to publish on Android).

Note: Apple reviews every update, typically 1–3 days. Plan releases accordingly β€” a bug fix can't go live the same day on iOS.

No-Code vs Native: Real Cost Comparison

For the same mid-complexity app:

| | No-Code (FlutterFlow) | Native (React Native) | Native (Swift+Kotlin) | |---|---|---|---| | Development | €15–30K | €60–120K | €80–180K | | Timeline | 4–6 weeks | 4–6 months | 5–8 months | | Monthly tools | €100–200 | €50–100 (hosting) | €50–100 (hosting) | | First major update | €3–8K | €15–30K | €20–40K |

The no-code advantage is largest at the MVP stage. At scale (50,000+ DAU), the gap narrows because infrastructure costs grow regardless of the tech stack.

Hidden Costs to Budget For

**Third-party services**: Push notifications (OneSignal, free tier usually sufficient), analytics (Mixpanel $25/month or Amplitude), error tracking (Sentry $26/month). Budget €100/month for third-party services.

**Ongoing maintenance**: Budget 15–20% of development cost per year for updates, dependency upgrades, and new FlutterFlow versions.

**App Store compliance**: Privacy policy, data deletion flow (Apple requirement), GDPR compliance for EU users. These should be built in from day one β€” retrofitting is expensive.

**Design assets**: App icons (1 icon in all required sizes), splash screen, screenshots for the App Store listings. Budget €500–2,000 for professional assets.
