When is React Native with GMI not the best fit?
Gaming, 3D or AR at native level
For heavy 3D or AR experiences, native stacks or a game engine are often a better fit.
Your team already ships only Flutter/Dart
If hiring and delivery are Flutter-only, switching to RN without a business reason slows delivery.
Very small scope with no growth plan
For a tiny PoC without backend integrations a freelancer may suffice - we focus on production apps.
A mobile product, not a rushed APK
Capabilities serious brands expect
Expo and React Native are our default for products that must feel native, work offline, use device hardware, and ship without drama - the same bar as large-scale rollouts.
One codebase, two stores
React Native and Expo: faster iteration than maintaining two native codebases, with native modules when the product truly needs them.
Push and in-app inbox
Segmentation, deep links, and transactional flows - from reminders to operations messaging, without burning user trust.
Offline-first sync
Queued actions in the field, retries, and conflict handling - so weak signal does not block revenue.
Hardware and permissions
Camera, scanning, Bluetooth, NFC, location, and sensors - when the product is more than flat screens.
Store releases & OTA
App Store and Google Play publishing plus JavaScript updates without a full store review cycle - shorter path from fix to user.
Cooperation process
How does our cooperation look like?
A transparent process that leads from idea to finished product
01
DDT: scope and risks
Workshops, MVP priorities, integrations, and architecture, ending with a spec, prototype, and fixed-price quote.
02
UX and prototype
We design and validate key journeys before coding, creating one consistent experience for iOS and Android.
03
Build and quality assurance
The app, backend, integrations, and testing move through one team and one release cadence.
04
Store release and growth
We handle App Store and Google Play, switch on monitoring, and evolve the product using real data.

Why GMI
We do not bolt an app onto your system. We own the whole product outcome.
Strategy, UX, React Native, backend, and store release sit in one team, so product decisions do not disappear between vendors.
One team from prototype to stores
Design, mobile, backend, and QA work from one scope. You do not manage four separate vendors.
Risks resolved before development
DDT validates integrations, offline behavior, permissions, and store requirements before price and timeline are locked.
After launch, outcomes drive the roadmap
Analytics, error monitoring, and releases follow retention, conversion, and real user behavior.
FAQ
Frequently asked questions about mobile apps
How much does a React Native app cost at GMI Software?
Ballpark: loyalty MVP EUR 18-28k, commerce app with integrations EUR 35-55k, full CRM-style mobile EUR 45-70k. Initial estimate within 48 hours; fixed price after DDT.
Is React Native production-ready?
Yes. The SFD app built by GMI Software in React Native hit 100,000+ downloads and 4.9★ on the App Store (Mobile Trends Awards 2025 Commerce nomination).
How long does mobile app development take?
A simpler production MVP usually takes 3-5 months. Apps with complex integrations, offline workflows, or multiple user roles typically take 5-10 months. DDT turns that range into a delivery plan by resolving scope, UX, architecture, and risk first.
Do I own the source code after delivery?
Yes. GMI Software transfers full IP and source code after project completion. No vendor lock-in.
Analytics from day one
On a greenfield build, React Native migration, or major modernization we build the tracking plan alongside code - funnels, CDP, and server-side measurement without a last-minute bolt-on.
- One event dictionary for iOS and Android
- Conversion funnels from entry to purchase
- Dashboards and marketing team onboarding
