Innostax builds iOS, Android, and cross-platform mobile apps with a dedicated Tech Lead who owns delivery end-to-end — from architecture decisions to App Store submission. We've shipped consumer apps with 100,000+ downloads and enterprise mobile tools for regulated industries.
THE PROBLEM
Most mobile projects focus on getting to launch. The hard part comes after — when real users encounter edge cases your test suite didn’t cover, when a platform update breaks something that was working, when the codebase that made sense at 1,000 users becomes unmanageable at 100,000.
The difference between a mobile app that scales and one that doesn’t comes down to decisions made before the first sprint: native vs. cross-platform, state management approach, offline handling, push notification architecture, analytics instrumentation.
Get these right early and you’re building on solid ground. Get them wrong and every new feature costs more than the last.
Innostax’s Tech Leads have made these decisions before. They’ll make the right ones for your product — and they’ll be accountable for the outcome.
Mobile App Skills That Scale
Every engagement is different. Use the links below to explore focused pages for this service.
Native iOS apps for consumer and enterprise. Built in Swift, following Apple's Human Interface Guidelines, with the performance and platform integration that native development makes possible. The right choice when your product needs deep iOS integration — widgets, Siri shortcuts, HealthKit, ARKit — or when App Store performance metrics are critical to your growth.
Learn more →Native Android apps built in Kotlin, optimised for the diversity of Android devices and OS versions your users actually have. Material Design, adaptive layouts, and the performance characteristics that matter for Android's fragmented hardware landscape.
Learn more →One codebase, both platforms — without the UX compromises that gave cross-platform a bad reputation. React Native is our primary cross-platform framework: mature, widely adopted, and capable of near-native performance when implemented correctly. The right choice for most consumer and B2B mobile products that need to ship on both platforms without maintaining two separate codebases.
Learn more →For teams that need a single codebase across mobile, web, and desktop — or that need pixel-perfect custom UI that React Native's component model doesn't accommodate cleanly. Flutter's rendering engine gives you full control over the visual layer, which matters for design-led products.
Learn more →For products where a full native app isn't justified but mobile-quality UX is required. Offline capability, push notifications, home screen installation — without App Store submission or native codebase maintenance.
Learn more →Existing mobile apps that need performance work, platform update compatibility, or a codebase that's become difficult to extend. We assess, plan, and improve incrementally — without the risk of a full rewrite.
Learn more →During discovery, the Tech Lead makes a clear recommendation based on your product requirements, target platforms, team structure, and timeline — not based on what’s easiest to staff. If React Native is the right choice, we’ll tell you why. If native is the right choice, we’ll tell you that instead.
AI generates a full implementation plan before development begins. The Tech Lead and engineers review it, challenge the approach, and correct it. For mobile specifically, this is where offline handling, state management, and platform-specific edge cases get surfaced before they become sprint problems.
iOS and Android have different performance characteristics, different review processes, and different failure modes. Our review chain accounts for both — Tech Lead review includes platform-specific checks, and QA covers the device and OS matrix your users actually use.
AI review (confidence-scored), peer review, Tech Lead review, architect sign-off. Every merge. Clean, maintainable mobile code isn’t a goal — it’s a gate.
We handle the submission process — metadata, screenshots, review guidelines compliance — and stay engaged post-launch for the stabilisation period that every app needs after real users start using it.
Your Tech Lead, your product requirements, real architecture decisions being made and real features being built. You’ll see the technical judgment and the delivery process before you commit. If it’s not right, walk away. No invoice.
Mobile projects go wrong when you’re locked into a vendor who’s already spent your budget. We remove that entirely — if we’re not delivering to the standard we committed to, you’re out tomorrow.
Great Place to Work certified — the mobile engineer who learns your app’s architecture in month one is still accountable for it in month six. Mobile codebases are complex enough that continuity isn’t a nice-to-have, it’s a quality requirement.
CLIENT OUTCOMES
Nuw
100K+ Downloads • 97% Retention • Top 10 ranking
Innostax built and scaled the Nuw React Native app for a US market launch. The result: over 100,000 downloads, a 97% user retention rate, and a top 10 ranking in the shopping category on both App Store and Google Play. A 97% retention rate isn’t a launch metric — it’s a signal that the app works the way real users expect it to.
Elate Wellbeing
Long-term mobile development and maintenance — the kind of engagement that only works when the codebase stays clean enough to keep building on.
"I have very good working experience with Innostax for developing and maintaining mobile app for my business. Their team is very qualified and professional."
Consumer app founders who need a mobile development partner with the architectural judgment to build something that retains users — not just something that launches. The App Store is full of apps that worked in a demo and failed in production.
B2B product teams adding mobile to an existing product. You have a web platform that works. You need a mobile app that integrates with it cleanly, matches your product’s quality standard, and doesn’t require your internal team to become mobile specialists.
CTOs extending their mobile capability who need React Native or native iOS/Android engineers that can integrate into an existing team and codebase without introducing patterns that conflict with what’s already there.
Tech stack
The tech lead selects the right combination from this stack based on your product requirements, scale targets and integration needs.
It depends on your product requirements, not on what's easiest to staff. React Native is the right choice for most consumer and B2B apps that need to ship on both platforms — it delivers near-native performance and significantly reduces development and maintenance overhead. Native is the right choice when your product requires deep platform integration (HealthKit, ARKit, platform-specific widgets) or when App Store performance metrics are critical to your growth model. The Tech Lead will make a clear recommendation during discovery, with the reasoning behind it.
Android fragmentation is a real problem and we treat it as a first-class concern, not an afterthought. During development, we test against a representative matrix of devices and OS versions — not just the latest flagship. The Tech Lead establishes the minimum supported OS version during discovery, based on your target market's actual device distribution.
The same team that built the app handles post-launch support — bug fixes, performance optimisation, platform update compatibility, and the next feature set. You're not handed off to a support team who doesn't know the codebase. The Tech Lead who made the architectural decisions is still accountable for the product after launch.
We handle the full submission process — metadata, screenshots, review guidelines compliance, and the back-and-forth with Apple and Google review teams if issues arise. We've been through the process enough times to know where rejections happen and how to avoid them.
Yes. We start with a technical assessment — understanding the current architecture, identifying the decisions that are limiting your velocity or causing stability issues, and building a plan to address them. We improve incrementally, not through a big-bang rewrite, so your users aren't disrupted while we work.
