App Development
Mobile apps people keep open.
We build cross-platform iOS and Android apps that feel native, perform reliably, and run from one clean React Native codebase — so you ship faster and maintain less. From MVP to App Store launch, FortifiLab handles product, engineering, and release.
One codebase, two stores
React Native means a single codebase for iOS and Android — faster delivery and simpler long-term support.
Launch-ready
We handle store submission, review requirements, and release pipelines, not just the build.
Built to scale
Analytics, crash reporting, and clean architecture from day one so the app grows with your users.
What you get
- iOS & Android (React Native)
- App MVP & product strategy
- Push notifications & deep links
- Offline sync & real-time data
- App Store & Play Store delivery
- Post-launch support & updates
Stack
How we work
A clear, low-risk process
Product & UX scoping
We define the core user journeys and cut the MVP to what proves value, then agree platforms, scope, and budget.
Design & architecture
Screen flows, navigation, and the offline/real-time data layer are designed before build so the app feels coherent.
Build & test on device
Weekly builds you can install on your own phone via TestFlight / internal track — feedback happens on real devices.
Store launch & iterate
We handle App Store and Play Store submission, then support updates, analytics, and the next round of features.

Frequently asked
Do you build native or cross-platform apps?
We specialize in cross-platform apps with React Native, which covers iOS and Android from one codebase. For cases that need it, we drop down to native modules.
How long does it take to build a mobile app?
A focused MVP typically takes a few weeks to a few months depending on scope. We define milestones upfront so you always know what ships when.
How much does it cost to build an app?
Most app MVPs start in the low five figures and scale with features, integrations, and platforms. We scope to a fixed range after understanding your core user journeys.
Do you help get the app approved on the App Store and Play Store?
Yes — store submission, review guidelines, and release management are part of delivery, not an afterthought.
Can you maintain and update an existing app?
Yes. We take over existing React Native (and some native) apps to fix, modernize, and add features.
