Native iOS & Android App Development
Build native apps in Swift and Kotlin where performance, hardware access, and platform behaviour matter more than a shared codebase.
Mobile App Development
Mobile apps built to ship, survive review, and keep their ratings
TxLabz designs, builds, and ships mobile apps for iOS and Android — native where it matters, cross-platform where it pays — with offline behaviour, payments, push, and store release handled as part of the build instead of discovered at submission.

Who This Is For
Best for teams launching a first mobile product, rescuing an app that stalled in review or ratings, or rebuilding a prototype into something that can carry real users.
Common Starting Points
- A prototype works on the founder's phone but falls over on real devices, real networks, and real data volumes.
- App Store or Play review keeps rejecting the build and nobody on the team knows why.
- The mobile app and the web product have drifted apart, so every feature now gets built twice.
What We Cover
Services inside this category
Cross-Platform Apps with React Native & Flutter
Ship to both platforms from one codebase where it genuinely saves time and money, without giving up native feel.
Mobile MVP & First Release
Take a mobile product from concept to a store-ready first release fast enough to learn from real users before the budget is spent.
App Rescue & Modernization
Take over a stalled, unstable, or inherited app, stabilize the release, and rebuild the parts that block every new feature.
Push, Payments & Device Integrations
Add notifications, in-app purchases, subscriptions, maps, camera, biometrics, and offline sync as first-class parts of the product.

Our Process
How TxLabz delivers this work
01
Product and platform scoping
We define the core flows, target devices, offline behaviour, and whether native or cross-platform is the honest answer for your product.
02
Experience and architecture design
We design the interface against platform conventions and map state, sync, and API contracts before the first screen is built.
03
Build, test on real devices, iterate
We ship to TestFlight and internal tracks early and often, testing on real hardware and real networks rather than a simulator.
04
Store release and post-launch care
We handle submission, staged rollout, and crash monitoring, then fix what real usage exposes in the first weeks.
Why TxLabz
What sets our delivery apart
01
The network is not always there
We design for offline and flaky connections from the first sprint — local state, sync, and conflict handling — because retrofitting it later means rewriting the app.
02
One codebase where it pays, native where it counts
We pick React Native, Flutter, or fully native per product rather than per fashion, and we tell you which one your case actually justifies.
03
Release is part of the build
Signing, store metadata, staged rollout, crash reporting, and update strategy are scoped up front, so launch day is uneventful.
FAQ
Common questions before engaging
01
Should we build native or cross-platform?
It depends on what the app does. Heavy camera, sensor, background, or animation work usually justifies native Swift or Kotlin. Most content, commerce, booking, and internal apps ship faster and cost less on React Native or Flutter with no user-visible difference. We make that call during scoping and explain the trade-off rather than defaulting to one stack.
02
How long does it take to launch a mobile app?
A focused first release is typically 6 to 12 weeks depending on scope, integrations, and whether the backend already exists. You get testable builds throughout, so you are never waiting until the end to see progress.
03
Can you take over an existing app someone else built?
Yes. We start with a short audit of the codebase, dependencies, and release setup, then give you an honest assessment of whether it is cheaper to continue the existing app or rebuild the parts that are holding it back.
04
Do you handle App Store and Google Play submission?
Yes. Signing, provisioning, store listings, privacy declarations, staged rollout, and review responses are part of the engagement. Most rejections we see are avoidable and get resolved before submission.
