Cross-platform Flutter, React Native, and native iOS/Android apps

We build mobile apps that pass App Store review the first time, survive the top-100 chart, and still feel fast on a three-year-old Android. Our team ships in Flutter, React Native, Swift, and Kotlin depending on what the product actually needs.

Notable apps our team has built and operated: AI MATE (100K+ downloads, 4.5-star rating), Second Texting Number (millions of monthly messages in the US), and PixelsCraft (AI-powered creative companion). We know what breaks under real-world usage.

What You Ship With NerdDevs

What We Build

Six focus areas where we bring deep, shipped-in-production experience.

Flutter Apps

One codebase for iOS and Android when design fidelity and velocity matter — our default for MVPs and content-driven consumer apps.

React Native Apps

When you need to share code with a web product or tap into an existing JS/TS team.

Native iOS / Android

Swift + SwiftUI, Kotlin + Jetpack Compose when the product needs deep platform integration, performance, or hardware access.

Backend for Mobile

Auth, realtime sync, push notifications, in-app purchases, receipt validation, and offline queues.

Store Submission

App Store Connect, Play Console, provisioning, signing, review-ready metadata, and rejection recovery.

Growth Instrumentation

Analytics, attribution, crash reporting, A/B testing, and feature flags for safe rollout.

Frequently Asked Questions

Flutter or React Native — which should we choose?

Flutter when design fidelity and smooth animations matter (most consumer apps); React Native when you have an existing JS/TS team or want to share logic with a web app. We do a one-week tech-selection sprint at the start if the answer is not obvious.

Do you handle App Store and Play Store submission?

Yes. Provisioning, signing, screenshots, metadata, age ratings, in-app purchase review, export compliance — we take care of the whole submission. If a review rejects, we handle the response.

Can you add a mobile app to our existing web backend?

Yes. Typically we audit the existing API, add mobile-specific endpoints (pagination, push tokens, delta sync), and ship the app against the same backend — no rewrite required.

How do you handle mobile payments and subscriptions?

Apple IAP and Google Play Billing are mandatory for most consumer apps. We wire them through RevenueCat or a thin backend service, handle receipt validation, and add Stripe on the web side for cross-platform families.
