Overview

Cross-platform mobile, without the cross-platform compromises

We build mobile apps with React Native and Expo because it is genuinely the right answer for ninety-five percent of products being launched in Pakistan today: one codebase, two app stores, a fraction of the cost, and performance that is indistinguishable from native for the vast majority of UX.

We have shipped buyer apps, seller apps, supplier apps, fitness apps connected to hardware sensors, real estate marketplace apps with multi-role flows, and security camera companion apps with live video streaming. We know where React Native ends and a native module needs to start, and we are comfortable writing those native modules when the product needs them.

When you work with DevKey on a mobile build, you get a published, store-listed app — not a debug APK. We handle Apple and Google submission, store assets, ASO basics, push notifications, crash reporting, and the over-the-air update pipeline you will want after launch.

One codebase, two stores

iOS and Android shipped from a single TypeScript codebase — faster, cheaper, easier to maintain.

Store-ready, not demo-only

We publish your app — Apple Developer setup, Play Console listings, store assets, review escalations.

Native when it matters

Bluetooth, camera streaming, secure enclave, background tasks — we drop into native modules when React Native can't reach.

Over-the-air updates

Push critical fixes to users without a new store submission — every project ships with EAS Update wired in.

What we actually deliver

Capabilities that ship together, not as eight separate sales pitches. Every project blends the ones your problem needs.

Submission, store listings, screenshots, and basic ASO done with you.

Frequently asked questions

The answers prospective clients usually want before the first call.

For ninety-five percent of products launching today, React Native is the right call — one codebase, two stores, a fraction of the cost, indistinguishable performance for normal app UX. We only recommend going fully native when you are doing heavy real-time camera work, deep ARKit / Core ML integration, or shipping a single-platform consumer app at huge scale.
