Nexus Code Lab designs and builds iOS and Android apps end to end — from the first wireframe to App Store and Play Store launch — with one team responsible for the whole product, not just one slice of it.
We build both native (Swift/Kotlin) and cross-platform (React Native/Flutter) apps, and help you pick the right approach based on your budget, timeline, and how much the app leans on platform-specific features.
Every build is mobile-first from day one — real device testing, offline handling, and push notifications aren't an afterthought bolted on before launch, they're part of the plan from the first sprint.
Native where it pays off, cross-platform where it saves time and budget — decided per project, not by default.
Swift and Kotlin builds for apps that need deep platform integration, maximum performance, or the latest OS-level features on day one.
One codebase for both platforms, when that's the right trade-off — faster to build, faster to update, and easier to maintain going forward.
Local storage and sync logic built so the app stays usable on a weak connection, not just when signal is perfect.
Listing copy, screenshots, and keyword targeting handled as part of launch, so the app is actually findable once it's live.
The same discipline behind DOS ERP, applied to mobile — a defined process at every stage, not a black box until launch day.
We start by mapping what the app needs to do, who it's for, and which platform strategy — native, React Native, or Flutter — fits your budget and timeline best.
This stage ends with a clear feature list and technical plan, so there's no ambiguity about what's being built before any design work starts.
Wireframes and clickable prototypes come first, built around each platform's own interface conventions rather than a single generic layout stretched across both.
You review and approve the flow on a prototype you can actually tap through, before a single line of app code is written.
We build in short, reviewable sprints, with a working build you can install and test on a real device at every milestone — not just a demo video at the end.
API integration, authentication, and push notifications are built and tested alongside the UI, so backend issues surface early, when they're still cheap to fix.
Before launch, the app is tested across a spread of real iOS and Android devices and OS versions — not just a single simulator — to catch layout, performance, and offline-handling issues that only show up in the real world.
Crash reporting and analytics are wired in before release, so post-launch issues are visible immediately instead of surfacing as one-star reviews.
We handle store listing setup, screenshots, and submission for both the App Store and Google Play, including the review-process back-and-forth so it's not left to you to navigate alone.
Push notification setup and app store optimization are part of this stage too, so the app is positioned to be found, not just approved.
Apps need upkeep — new OS versions, device sizes, and store policy changes all land after launch. We offer ongoing maintenance so the app keeps working, not just on the day it shipped.
Feature updates and version releases follow the same tested, staged process as the original build, so quality doesn't slip after the first release.
