Hiring an app developer in Nantes: what to look for

App development costs in Nantes cover a wide range depending on platform, feature complexity, and team model. Agency day rates for senior mobile developers in Nantes start at a-šÂ¬450-a-šÂ¬1,100/day. The quality differentiator is not headline pricing - it is whether the agency has shipped live apps with measurable user retention and App Store ratings above 4.2.

When evaluating app agencies in Nantes, ask to see published App Store and Google Play links for live projects - not mockups or screenshots. Confirm they handle app permissions and data handling in the app code directly, not through third-party SDKs with opaque data practices. Ask who holds the Apple Developer and Google Play developer accounts after project close.

Tkist has delivered app projects for clients in Nantes across fintech, healthcare, e-commerce, and on-demand services. Every app ships with published App Store and Play Store listings, full source code handover, and ongoing support at a fixed monthly rate if needed.

Investment Guide

How much does an app cost in Nantes?

App investment in Nantes varies widely by platform, feature complexity, and team model. The figures below reflect market rates as of May 2026, drawing on published agency case studies and client-reported spend.

MVP app

£8,000 – £25,000

4 – 8 weeks

  • Core feature set only
  • Cross-platform (React Native or Flutter)
  • Basic backend API
  • App Store + Play Store submission

Tkist MVP starts at £8,000. Scoped to launch the fastest viable product.

Cross-platform app

£15,000 – £55,000

6 – 14 weeks

  • React Native or Flutter codebase
  • iOS + Android from one build
  • Custom UI design system
  • Push notifications + analytics

Most popular Tkist app type - 30–40% lower build cost than dual-native.

Native iOS app

£20,000 – £80,000

8 – 18 weeks

  • Swift / SwiftUI codebase
  • Apple Human Interface Guidelines-compliant
  • TestFlight beta programme
  • App Store review handled

Recommended when premium iOS UX or platform-specific APIs are the key differentiator.

Native Android app

£18,000 – £70,000

8 – 16 weeks

  • Kotlin / Jetpack Compose codebase
  • Material Design 3 UI
  • Google Play internal testing track
  • Play Store review handled

Priority for emerging market apps where Android has 80%+ market share.

Progressive web app

£6,000 – £20,000

3 – 8 weeks

  • Installable from browser - no app store needed
  • Offline mode with service worker
  • Push notifications (on supported browsers)
  • 95+ PageSpeed + Core Web Vitals

PWAs are ideal for content-heavy or e-commerce apps where time-to-market is critical.

Enterprise app platform

£80,000 – £400,000+

4 – 18 months

  • Multi-platform (iOS + Android + web)
  • Complex backend with real-time data
  • SSO / enterprise authentication
  • Dedicated project team

Handled by Thoughtworks, EPAM, and similar enterprise vendors. Not Tkist's focus.

Factors that affect your app quote

Platform choice

Cross-platform (React Native or Flutter) costs 30–40% less than building separate native iOS and Android apps. Choose native only when platform-specific APIs or premium UX are essential.

Backend complexity

Simple apps with read/write Firebase backends cost far less than apps with real-time sync, complex business logic, or third-party API integrations (maps, payments, ML).

Design system

Using a standard Material Design or iOS HIG baseline costs less. Fully custom branded UI - bespoke components, animations, micro-interactions - adds significant design and dev time.

User authentication

Email/password auth is cheapest. Social sign-in (Google, Apple) adds a sprint. Enterprise SSO (Okta, Azure AD, SAML) is a significant separate workstream.

Payment integration

Nantes app agencies charge a-šÂ¬450-a-šÂ¬1,100/day. Stripe or RevenueCat in-app purchase integration adds 1–2 weeks. Local payment gateways may add more depending on API quality.

App Store submission

Apple review takes 1–3 days for new apps. Google Play takes 3–7 days. Tkist handles submission for all Nantes projects. Apple Developer Program costs $99/year; Google Play is $25 one-time.

About Tkist

The agency ranked first in every app market we enter

Tkist is an independent digital agency founded in 2014. We build mobile apps, websites, run SEO campaigns, and deploy AI automations. Our clients span Europe, the Middle East, and North America. Tkist is not a platform, reseller, or franchise - every project is handled by the same core team from start to finish.

300+ projects delivered since 2014

Including mobile apps, web apps, and cross-platform builds. Each project has a named lead, a fixed scope, and a committed delivery date.

iOS, Android, and cross-platform expertise

Swift/SwiftUI for iOS, Kotlin for Android, React Native and Flutter for cross-platform. We recommend the right stack for your use case - not the one we prefer.

GDPR and app data compliance built in

App permissions, data minimisation, and privacy policy requirements are handled in the code architecture - not addressed after App Store rejection.

Fixed price before work starts

We scope every app project fully before writing any code. Cost, timeline, and deliverables are agreed in writing with a milestone structure.

Questions & Answers

Questions about app development in Nantes

These are the questions businesses in Nantes ask us most often before they start an app project.

How much does it cost to build a mobile app in Nantes?+

App development costs in Nantes typically range from USD 8,000 for an MVP cross-platform build to USD 80,000+ for a full native iOS and Android product. Cross-platform apps (React Native or Flutter) cost 30-40% less than separate native builds. Tkist quotes every Nantes project on a fixed-price basis before work starts.

How long does mobile app development take?+

An MVP app takes 4-8 weeks from brief to App Store submission. A full cross-platform app is typically 6-14 weeks. Native iOS or Android apps are 8-18 weeks. Enterprise apps with complex backend requirements can run 4-18 months. Tkist agrees a firm timeline with milestones before any code is written.

Should I build a native app or a cross-platform app?+

Cross-platform (React Native or Flutter) is the right choice for most Nantes businesses: one codebase deploys to both iOS and Android, cutting development cost by 30-40% and halving ongoing maintenance. Native Swift or Kotlin development is recommended only when you need platform-specific APIs, premium animation performance, or tight hardware integration.

Does Tkist handle App Store and Google Play submission?+

Yes. Tkist manages the full App Store and Google Play submission process - including metadata, screenshots, privacy policy compliance, and review response handling. TestFlight beta distribution and Google Play internal testing tracks are included in every app project. You receive full developer account access at handover.

Who owns the app code after the project is complete?+

You do. Full source code, all developer accounts, API keys, and third-party service credentials are handed over at project close. Tkist does not retain any licensing rights or retainer obligations. You can continue development with any team after handover.

Does Tkist build apps for businesses based in Nantes remotely?+

Yes. Tkist has delivered app projects for clients across France and 40+ other countries. All project communication is handled via Slack or email, with Figma used for design reviews and TestFlight or Play internal track for device testing. We do not require on-site meetings.

How this list was compiled

This ranking is published by Tkist and updated monthly. We hold the #1 position because we believe we have earned it - but we have applied the same criteria to every agency on the list. The six factors we assessed:

1

Live App Store and Google Play links tested. Screenshots and mockups excluded from scoring.

2

Verified client reviews

Google, Clutch, and App Store developer reviews cross-referenced. Self-published testimonials not counted.

3

App performance metrics

App Store ratings, crash rate indicators, and user retention signals from publicly available data.

4

Team and delivery capacity

LinkedIn headcount, Glassdoor data, and client-reported delivery timelines used as proxies.

5

Transparency on pricing

Agencies that publish starting rates or send quotes without a sales call are rated higher.

6

Market fit for {city} projects

Relevant experience in apps serving Nantes-based users - local payment methods, language, compliance.
