Mobile Apps
Apps people keep on the home screen
Native and cross-platform builds engineered for retention, not just launch day. A working prototype on your phone by day 14.
Your App
Home
Why our apps win
Retention is the only vanity-free metric.
Performance-budgeted
A 60fps budget enforced in CI — animations that stutter don't merge.
Pixel-accurate UI
Design QA against the Figma file, screen by screen, before every release.
Offline-first
Queued writes and conflict resolution, so the app works on the subway and syncs later.
Store-savvy
We've shipped 60+ store submissions; rejections are edge cases we've already met.
Capabilities
The right stack, argued honestly.
We'll tell you when Flutter saves you six figures — and when only native will hit your performance bar.
iOS (Swift)
SwiftUI-first apps that feel like Apple built them. ProMotion, widgets, App Intents.
Android (Kotlin)
Jetpack Compose, Material 3, and the device-fragmentation testing everyone else skips.
Flutter
One codebase, two platforms, pixel parity. Our default for content and commerce apps.
React Native
The pragmatic choice when your web team ships TypeScript and speed to market wins.
In the box, every build.
Not add-ons. Not "phase two." Every Auxtech app ships with the unglamorous infrastructure that decides whether users are still there in month three.
How it works
Strategy to store in five moves.
Product Strategy
Platforms, scope, and the one metric the app must move.
UX/UI Design
Prototypes tested on real devices in real hands — first live demo on day 7.
Agile Development
Weekly builds to your phone via TestFlight and Play internal track.
QA & Testing
A 40-device lab, performance profiling, and the edge cases reviewers punish.
Launch & Scale
Store submission handled end to end, ASO, and post-launch iteration.
Release machinery
From commit to store, on rails.
Shipping to two app stores every week takes machinery, not heroics. This runs on every build we deliver.
Stability, measured
Crash reporting is wired before feature one — regressions page us, not your app store reviews.
Green before it ships
The 60fps budget, the 40-device lab, and store guideline checks all gate the release — automatically.
Every build in your pocket
Weekly builds land on your phone via TestFlight and Play internal track — you test what users will touch.
Releases on command
Staged rollouts, promotions, and OTA updates are one-command operations — not release-day ceremonies.
Case study — Halcyon
From two-star legacy app to category leader in one rebuild.
Flutter rebuild of a failing native pair. Shipped to both stores in 16 weeks, with the offline sync layer their users had been begging for in reviews.
Beyond the build
The app is the start, not the deliverable.
MVP Development
A lean, store-ready first version in 8–14 weeks to test demand with real users.
App Modernization
Rescue aging Objective-C and Java codebases without a big-bang rewrite.
Mobile Analytics
Event taxonomy, funnels, and cohorts — so 'how's the app doing' has a number.
Wearable & IoT
watchOS, Wear OS, and BLE device integration when the phone is only half the product.
The 14-day prototype
A working prototype on your phone in 14 days.
Fixed price, fixed scope: your core flow, on your device, installable via TestFlight. Use it to raise, to test, or to fire us — the prototype is yours either way.
What partners say
Trusted by founders and product leaders.
"Our app hit 4.9 stars and doubled retention in the first quarter."
"Weekly builds on my own phone from week one. No agency has ever done that for us."
"Two OS releases since launch, zero fire drills. The Care plan pays for itself."
FAQ
Answers to common questions.
Native or cross-platform?+
We model it against your roadmap: cross-platform when speed and parity win, native when performance, hardware access, or platform feel is the product. You get the reasoning in writing.
How long to launch?+
First live demo on day 7, a prototype on your phone by day 14, and a store-ready MVP typically in 8–14 weeks.
What about maintenance?+
Care plans cover OS updates, dependency patches, crash triage, and iteration. 84% of our clients stay on one — it's cheaper than the first fire drill it prevents.
Who owns the app and IP?+
You do — code, store listings, and accounts, all transferred at delivery under your own developer accounts from day one.
