Platforms we ship

Native, hybrid, or both.

We pick the right runtime for the outcome, not the trend. A senior pod owns iOS, Android and any cross-platform layer in between - so the choice never blocks the roadmap.

iOS (Swift / SwiftUI)

Native iPhone and iPad applications with SwiftUI, Combine, Core Data and full App Store delivery pipelines.

Android (Kotlin)

Jetpack Compose-led Android apps with Coroutines, WorkManager, Room and Play Store release engineering.

Cross-platform

React Native and Flutter for teams that need a single codebase without sacrificing native feel or performance.

Tablet & rugged devices

Field-ops apps for tablets, kiosks and rugged Zebra / Honeywell handhelds with barcode and NFC integrations.

What we build in

Six capabilities, in every app.

The defaults we apply to every mobile engagement - so your app works when the network doesn't, the device is locked, or the user is on the worst handset you support.

  • Offline-first sync

    Conflict-free local stores, background sync and queueing so your field teams keep shipping work when the network drops.

  • Push & messaging

    APNs, FCM, in-app messaging and behaviour-driven nudges with deep links that survive cold starts and reinstalls.

  • Biometric & SSO auth

    Face ID, Touch ID, passkeys, SSO/SAML/OIDC and SCIM provisioning - hardened against jailbroken devices.

  • Device & data security

    App attestation, certificate pinning, secure enclaves, MDM/MAM policies and at-rest encryption for sensitive payloads.

  • OTA updates

    Over-the-air JS bundles, staged rollouts and instant kill-switches without waiting on store review windows.

  • Crash-free telemetry

    Crashlytics, Sentry, OpenTelemetry traces and product analytics wired to SLOs - so regressions surface in hours, not weeks.

How we engineer

Prototype. Engineer. Submit. Operate.

A four-stage loop that runs every engagement - and every release inside it. Weekly TestFlight and Play Internal builds. Real devices, every demo.

  1. 01

    Discover & prototype

    Field research with real users, a clickable prototype and a costed delivery plan - in 2 to 3 weeks.

    Prototype + scoped backlog
  2. 02

    Design & engineer

    Senior pods ship reviewable builds to TestFlight and Play Internal every week against a shared roadmap.

    Weekly beta builds
  3. 03

    Harden & submit

    Performance budgets, accessibility audits, penetration tests and store-review hardening before every release gate.

    Store submission + audit pack
  4. 04

    Release & operate

    Phased rollouts, kill-switches, crash triage, OTA patches and managed release trains after launch.

    Live ops + 90-day support
How we build

Mobile work that moved the metric.

These are the targets we engineer to on every engagement.

Year-one impact
  • -62%Crash rate

    A retail handheld app rebuilt on Kotlin and Jetpack Compose for a national 3PL.

  • 4.8★App Store rating

    A patient-facing iOS app for a US healthcare system, launched in 11 weeks.

  • 70%Shared code

    A React Native rebuild that retired two native codebases for a fintech challenger.

  • HIPAAControls applied

    An ambient capture mobile app cleared US health system security review on first pass.

Mobile stack

Native-grade tools, pragmatically chosen.

Where it ships

Mobility for the workplace and the wallet.

The four scenarios we ship into most often - each with its own quirks, integrations and compliance bar.

  • Field service & logistics

    Driver, dispatcher and warehouse apps with offline sync, barcode and signature capture.

  • B2B SaaS companions

    Native iOS and Android companions for your web SaaS - dashboards, approvals and alerts.

  • Regulated workflows

    HIPAA-aware patient apps, FCA-aligned banking apps and audit-ready insurance mobility.

  • Consumer & loyalty

    Storefronts, loyalty, scan-and-pay and in-store assist apps tied to your commerce backend.

Why SyncTrix

Mobile, owned end-to-end.

One pod for the app, the backend, the store and the live rollout - no handoffs, no finger pointing on launch day.

  • Native feel, every time

    Whether native or cross-platform, every screen ships against a strict gesture, motion and accessibility checklist.

  • Store delivery, owned

    We own the Apple and Google relationship - submissions, reviewer responses, expedited reviews and policy escalations.

  • Localized & accessible

    RTL, dynamic type, VoiceOver, TalkBack, locale and currency - tested in every release, not bolted on at the end.

  • Built for the real world

    Low-bandwidth, intermittent connectivity, low-spec devices and battery budgets are tested - not assumed away.

SyncTrix shipped our driver app to four thousand handsets without a single crash on day one. Their pod owned the OTA pipeline, the MDM rollout and the store submission - we just watched the dashboards.

Frequently asked

Straight answers, no sales talk.

The questions that come up on most first calls. If yours is not here, ask us directly - we will write back the same week.

  • We default to React Native or Flutter when feature parity across iOS and Android is the priority and the app is mostly forms, lists and integrations. We choose native (Swift / Kotlin) when you need deep platform APIs, AR/ML, low-level performance or strict App Store optimisation. We will recommend the honest fit during discovery.

  • Yes. Most engagements embed alongside in-house mobile engineers. We share repos, contribute to your release trains, follow your review gates and uplift your CI / device-lab infrastructure as we go.

  • We own the entire submission loop - metadata, screenshots, policy reviews, reviewer Q&A and expedited review escalations. Our pods include senior engineers who have shipped 50+ apps across both stores.

  • We deliver against Intune, Jamf, Kandji, Workspace ONE and Apple Business Manager / Google Managed Play. Enterprise SSO, conditional access, app config and per-app VPN are part of our default checklist.

  • Yes. Every engagement includes a 90-day live-ops window with crash triage, OTA patching, store rating monitoring and SLO reviews. Most clients extend into a long-term managed mobility partnership.
