A practical mobile team that also understands how apps get found and installed.
We start by mapping screens, data flow and the native features you actually need, like camera, push notifications, payments or location. Then we decide on navigation, state management and whether to use Expo or a bare React Native workflow. This avoids the common trap of rebuilding the foundation halfway through the project.
Most UI and logic is written once in TypeScript and runs on both iOS and Android. When a feature needs native performance or a platform SDK that has no ready bridge, we write the native module in Swift or Kotlin and connect it. You get one codebase to maintain without giving up access to device hardware.
We test on actual iPhones and Android phones across a range of OS versions and screen sizes, since simulators hide real gestures, memory limits and performance issues. We check cold start time, list scrolling and offline behaviour. Bugs that only show up on older or budget Android devices get caught before release, not after.
We prepare builds for the Apple App Store and Google Play, including signing, store listings, privacy declarations and review guidelines that often cause rejections. After launch we monitor crashes, ship updates and tune slow screens. React Native also lets us push certain JavaScript fixes without waiting for a full store review.

Their attention to detail and compliance-focused approach helps build a stronger and more sustainable business. Initially they ask for documentation many sellers find difficult to provide. that is exactly what sets them apart. They now also offer USA seller account management. Loved the service. Bestseller in 3 category.

Dcrayons has built and shipped digital products since 2016, with teams in Delhi and the US. We treat a React Native project as a product, not a one-off deliverable, which means clear scope, code you can maintain, and support after the app goes live. Because we also run SEO, content and paid media in house, we can help with the part most app teams ignore: getting people to actually find and install what you built.
One codebase for iOS and Android, with native Swift or Kotlin modules added only where a feature genuinely needs them
Honest advice on when React Native is the right fit and when a fully native or web build would serve you better
Real questions people ask Dcrayons about react native app development. Honest answers, no jargon.
It is a team that builds mobile apps using React Native, a framework that lets one codebase run on both iOS and Android. Instead of writing and maintaining two separate native apps, you share most of the code while still accessing device features through native modules. Dcrayons handles scoping, UI, native integrations, testing and store submission for both platforms.
React Native is a strong fit for most content, commerce, booking and dashboard style apps where you want iOS and Android from one team and one codebase. It is less ideal for apps built around heavy 3D graphics, intensive on-device processing or platform-specific hardware that needs deep native control. We give you an honest read on your specific case before you commit to it.
A focused first version with a clear feature set typically takes a few months from kickoff to store submission, while larger apps with many integrations take longer. The biggest variables are the number of screens, backend complexity and how many native features like payments or maps are involved. We scope this in detail upfront so the timeline reflects your actual app, not an average.
Yes, the large majority of code is shared across both platforms, which is the main reason teams choose React Native. A portion of work still goes into platform-specific behaviour, such as different navigation patterns, permissions and store rules. We build and test for both so each platform feels native rather than like a copy of the other.
Yes. When a feature needs platform SDKs or native performance that React Native does not cover out of the box, we write native modules in Swift for iOS and Kotlin for Android and bridge them into the app. Common examples include advanced camera use, Bluetooth, background tasks and specific payment SDKs. The rest of the app stays in the shared JavaScript and TypeScript codebase.
Yes. We prepare and submit builds to the Apple App Store and Google Play, including signing, store listings and the privacy and review requirements that often cause rejections. Because Dcrayons also runs SEO, content and paid media, we can help with app store listing optimisation and download campaigns once the app is live.
