What We Do

End-to-end mobile engineering from architecture to store approval.

Building for iOS and Android doesn't mean maintaining two divergent engineering teams, splitting your product budget, or settling for sluggish web wrappers. We build cross-platform mobile products with Flutter and React Native that compile directly to native binaries with zero-jank UI.

From intuitive consumer mobile commerce and real-time delivery tracking to complex offline field tools and hardware integrations, we handle the entire product lifecycle: mobile UI/UX in Figma, native bridge engineering, backend API synchronizers, automated test suites, and ongoing release compliance.

Where This Fits

Choose the right platform surface for your users.

Native mobile apps, responsive web applications, and counter desktop tools solve fundamentally different operational constraints.

You Are Here

Mobile App Development

Dedicated iOS & Android applications on phones and tablets. Push notifications, camera/biometric access, background geolocation, and offline persistence.

Flutter · React Native / Expo
Browser Experience

Web Application & SaaS

High-converting websites and cloud dashboards accessible instantly in any desktop or mobile browser without store installation.

Front-Desk & Counter

Desktop App Development

Heavyweight desktop software for Windows and macOS. Deep local peripheral integration, sub-10MB installers, and local SQLite databases.

Key Challenges We Solve

Where typical mobile projects stumble.

App Store Rejections

Vague guidelines, privacy manifest non-compliance, and unexpected App Store rejections delaying marketing launches by weeks.

Unstable Offline Sync

Mobile apps that freeze or lose critical user data the second internet drops in elevators, basements, or rural areas.

Frame Jitter & Battery Drain

Unoptimized rendering cycles, memory leaks, and redundant background polling that overheat devices and trigger 1-star reviews.

Dual-Codebase Overhead

Paying two disconnected teams for separate Swift and Kotlin codebases, doubling bug backlogs and desynchronizing product roadmaps.

Why POSflow

We operate production mobile software, not just prototypes.

POSflow operates mission-critical restaurant management and point-of-sale systems that run on mobile tablets and handheld devices all day. The exact same standards for memory management, offline resilience, and hardware connectivity power our client builds.

01

60 FPS Native Performance

Compiled to native machine code using Flutter (Impeller/Skia) or React Native (Hermes engine) with zero stutter during high-velocity list scrolling.

02

Offline-First Architecture

Local SQLite and WatermelonDB synchronization ensure full operational capability with or without cellular connectivity.

03

Native Hardware Bridges

Deep integration with Bluetooth thermal printers, barcode scanners, NFC readers, camera scanners, and background GPS tracking.

04

Store Approval Guarantee

We handle privacy manifests, store metadata, screenshots, App Store Review guidelines, and Google Play 20-tester tracks end-to-end.

05

Over-The-Air (OTA) Updates

Instant bug fixes and UI updates pushed directly to users' devices without waiting days for App Store re-review cycles.

06

Full Code Ownership

Clean, documented TypeScript or Dart code pushed to your private repository. Zero vendor lock-in, zero proprietary runtime fees.

What We Build

Mobile applications engineered for commercial impact.

E-Commerce & Ordering

Fast visual catalogues, Apple Pay / Google Pay checkouts, one-tap reorders, and live order tracking with push notifications.

Offline Field & Inspection

Field inspection forms, inventory counts, and audits that store data locally and sync securely when connection returns.

On-Demand & Logistics

Rider and courier apps with battery-efficient background GPS geofencing, route turn-by-turn, and instant dispatch notifications.

Hardware & POS Handhelds

Tablet POS, handheld ordering terminals, and warehouse barcode scanners paired via Bluetooth or USB OTG peripherals.

FinTech & Secure Portals

Biometric authentication (FaceID/TouchID), encrypted local keychains, KYC document capture, and PCI-compliant transaction flows.

Customer Loyalty & Booking

Digital membership cards, Apple Wallet integration, real-time table reservations, and personalized segmented push alerts.

B2B Enterprise Dashboards

Executive KPI dashboards, real-time branch sales analytics, and role-based operational approval workflows for managers.

Healthcare & Appointments

Doctor scheduling, encrypted patient chat, prescription uploads, and HIPAA/GDPR-compliant telemedicine consultations.

Platforms & Frameworks

Flutter and React Native. The two industry standards.

We don't use obsolete hybrid webviews or experimental engines. We specialize strictly in the two production-proven cross-platform frameworks.

FlutterDart & Impeller Engine

Google's open-source framework that compiles directly to native ARM machine code. Renders every pixel using its own GPU-accelerated engine, ensuring 100% visual parity across every Android and iOS version.

Choose it when:

You require complex custom branded UI, high-speed fluid animations, hardware tablet displays, or guaranteed identical rendering across hundreds of different Android devices.

Architectural Trade-off:

Initial binary size is ~15–20MB due to bundled rendering engine; uses Dart rather than TypeScript.

Core Stack:
DartFlutter 3.xRiverpodBlocHive / SQLiteMethodChannelsFastlane
React Native & ExpoHermes & TypeScript

Meta's battle-tested mobile framework paired with the modern Expo application ecosystem. Invokes real native UI primitives with a high-speed Hermes JavaScript engine and seamless Over-The-Air deployment.

Choose it when:

Your team already has TypeScript/React expertise, you want to share data models and API client hooks with your Next.js web application, or you require instant Over-The-Air updates.

Architectural Trade-off:

Requires careful bridging when interfacing with esoteric C++ hardware SDKs that lack active React Native community packages.

Frequently Asked Questions

Everything you need to know about our mobile engineering.

We choose based on your product architecture and existing team capabilities. Flutter is ideal when your app requires pixel-perfect, custom-branded UI across iOS and Android with high-frequency graphics or heavy offline workflows (compiled directly to native ARM code via Skia/Impeller). React Native (with modern Expo) is optimal when your company already has a React/TypeScript web app and wants to share state management, API query hooks, and utility libraries across web and mobile. We evaluate your feature list and provide a transparent architectural recommendation before writing any code.
