iOS and Android applications engineered for performance, stability, and long-term maintainability
Mobile Application Development
We deliver end-to-end mobile application development: UX design, iOS and Android implementation, backend API engineering, and app store submission. Whether the application serves field workers, customers, or internal operations teams, we build for real-world device conditions — not just the demo environment.
Mobile performance is determined by engineering decisions, not device specifications
Sluggish list scrolling, janky transitions, slow API responses, and battery drain aren't hardware problems — they're symptoms of engineering shortcuts taken during development. We treat mobile performance as a first-class requirement: list virtualization, image pipeline optimization, network request batching, offline cache strategies, and background sync are standard engineering practices in our delivery process, not optional performance optimization passes after launch. Backend APIs are designed for mobile consumption patterns from the start — not adapted from a web API that was never intended for mobile network conditions.
Apps that shipped — but not to production quality
Mobile application quality problems cluster around four failure modes: device fragmentation, performance regression at scale, dual-platform maintenance cost, and security gaps that compound over time.
Android fragmentation creates a long tail of device issues
OEM Android customizations produce behavioral differences that are impossible to fully test in advance. Unhandled edge cases on specific device/OS combinations emerge post-launch as user complaints.
Performance issues surface only at production load
Scrolling and transition performance acceptable on a flagship development device deteriorates on mid-range hardware. Unoptimized list rendering, synchronous main-thread work, and memory leaks don't manifest until real usage.
Dual-platform maintenance doubles engineering cost
iOS and Android codebases maintained independently. Every feature is implemented twice. Every bug is fixed twice. Two release pipelines to manage. Maintenance cost scales with the feature set.
Mobile-specific security surface poorly managed
Local storage of sensitive data without encryption, insufficient certificate pinning, overly broad permission requests — mobile security requirements differ from web and require explicit engineering attention.
Push notification delivery is unreliable on Android
OEM Android customizations aggressively restrict background processes. Notifications from apps without manufacturer-specific SDK integrations or system-level permissions frequently fail to deliver — silently, with no error feedback.
Binary size drives abandonment before first use
Unoptimized asset bundling produces installer packages that exceed the user's willingness to download on mobile data. Large cold-start asset loads compound the problem after installation.
Technology selection and engineering discipline determine long-term quality
Framework choice, architecture patterns, and engineering standards established at project start define the performance ceiling and maintenance burden for the application's lifetime.
Native vs. cross-platform: documented tradeoff decision
Deep system integration, advanced graphics, or maximum performance requirements justify native development. Standardized functionality and budget constraints favor cross-platform. We document the tradeoff and recommend based on your specific requirements.
Performance engineering from day one
List virtualization, image caching pipeline, network request deduplication, and main-thread offloading are baseline requirements, not performance optimization tasks. Pre-production device testing covers the target hardware profile.
Mobile security requirements explicitly addressed
Data at rest encrypted. HTTPS enforced with certificate pinning where appropriate. Token storage in OS secure enclave. Permission requests minimized and documented. Security review part of pre-release checklist.
Maximum business logic code sharing across platforms
Data layer, state management, and business logic maximally shared between platforms. UI layer platform-specific where necessary. Feature changes touch shared code once — UI adaptation is the remaining delta.
Push notifications and offline capability
Push notification integration with proper token lifecycle management. Offline-first cache strategy with optimistic UI updates and conflict resolution on sync recovery. Network partition handling designed, not improvised.
Crash monitoring and analytics instrumented pre-launch
Crash reporting and user behavior analytics integrated before go-live. Post-launch issues are identified from telemetry data — not inferred from user complaint patterns.
From prototype to app store approval
Mobile delivery includes UX design, engineering, multi-device testing, and app store submission — all managed as a single engagement.
Requirements analysis & platform selection
User scenario mapping, feature scoping, and platform selection decision (native vs. cross-platform). Backend API requirements defined alongside mobile requirements.

UX design & prototype validation
Mobile-native UX design — not a web layout adapted for smaller screens. Interactive prototype for core flows tested with representative users before development begins.

Parallel mobile & API development
Mobile and backend teams work against shared API contracts. Mock server enables mobile development to proceed independently. Two-week sprint reviews with stakeholders.

Common application types
Mobile applications suit any scenario where users need anytime, anywhere access to business systems or services.
Enterprise field applications
Approval workflows, expense reporting, task management, and internal communications — enabling mobile productivity for office and field workers alike.
Customer service applications
Customer-facing service and product applications — order tracking, support, account management, and loyalty programs delivered through a native mobile experience.
Field operations tools
Inspection, maintenance recording, and data capture tools for frontline workers. Offline-first design for environments with unreliable connectivity.
O2O service applications
Booking, redemption, and location-aware services that bridge online and offline customer journeys.
Corporate learning & training

Why Metavun
End-to-end mobile delivery — UX, mobile engineering, backend API, and app store submission managed as a single engagement.
Full-stack mobile delivery
Mobile engineering, backend API, and UX design from one team. No handoff gaps between frontend, backend, and design vendors. Architectural coherence maintained across the stack.
App store submission experience
We know Apple and Google review requirements, common rejection causes, and escalation paths. App store delays from avoidable rejections don't happen to our engagements.
Performance is a delivery requirement
Mobile performance optimization is baked into our development process — not a post-launch pass. Target device profiles are tested, not assumed.
Long-term iteration support
Launch is the beginning of the product lifecycle. We support ongoing version releases, feature addition, and platform OS compatibility maintenance.
Android push delivery engineering
We've navigated manufacturer-specific push restrictions and iOS background delivery constraints across real production applications. Push reliability is an engineering problem we've solved — not a capability we claim abstractly.
Binary size optimization process
Asset compression, code splitting, dynamic delivery, and on-demand resource loading are applied systematically. We size apps appropriately for real-world download conditions, not just developer WiFi.
