Custom iOS and Android app development, end to end
Searching for an iOS and Android development company usually means you already know a website is not enough. Your users expect push notifications, biometric login, offline use, and a listing they can trust in the App Store and on Google Play. We treat those constraints as product requirements, not extras.
Native iOS development at Zupitrix means Swift, SwiftUI, and the Apple ecosystem: TestFlight, Sign in with Apple, Apple Pay, widgets, and Human Interface Guidelines. Native Android development means Kotlin, Jetpack Compose, Play Console tracks, and devices that range from flagship phones to budget hardware. When a single codebase is the better business decision, we still keep iOS and Android quality bars explicit so neither platform feels like a port.
Core capabilities
- Native and cross-platform clients on a shared API, with room to scale traffic and features after launch.
- UI/UX that follows Apple and Google patterns so retention is not lost to awkward navigation.
- AI, camera, and real-time features wired in when they have a job to do — not bolted on as a buzzword.
- Security defaults: encrypted storage, pinned TLS where needed, and store privacy disclosures done properly.
- Integrations with the rest of your stack: payments, identity, CRM, and custom backends.

What we deliver
Native mobile app development services
Whether you need a new iPhone app, a Play Store product, or both platforms in parallel, the suite below covers consulting through launch and the years of OS updates that follow.
Native iOS App Development
We design and engineer iPhone and iPad apps in Swift and SwiftUI, with UIKit where a mature codebase needs it. The work covers navigation, offline storage, push notifications, widgets, Apple Pay, and App Store submission — built to Apple Human Interface Guidelines so the product feels native, not ported.
• Scalable & Secure:
Build Swift and SwiftUI apps with Combine, Core Data / SwiftData, Keychain, and enterprise-ready privacy, data protection, and App Store compliance.
• Feature-Rich:
Ship widgets, Apple Pay, Face ID, TestFlight pipelines, App Store Connect listings, and privacy labels without a last-minute scramble.
Native Android App Development
Our Android team ships Kotlin apps with Jetpack Compose, Material 3, and the latest Android SDKs. We handle fragmentation across devices, background work, Play feature modules, and Play Console rollout so the app stays fast on both flagship and mid-range phones.
• Expert Guidance:
Plan Kotlin, Coroutines, Jetpack, Room, and Hilt architecture with a timeline from prototype to Play Store launch.
• Enterprise-Ready:
Deliver Play Console tracks, staged rollouts, Data safety forms, and API integrations that hold up on real Android hardware.
Dual-Platform Native Product Teams
When the product needs two first-class apps, we run iOS and Android in parallel with a shared product spec, design system, and API contract. You get platform-native UX without two disconnected roadmaps or duplicated business rules on the server.
• Shared Product Core:
One backend, analytics, and feature-flag strategy so business rules live once and both clients stay aligned.
• Parity Without Ports:
Plan releases so iOS and Android do not drift — native UX on each OS, same outcomes for users.
Mobile App Consulting & Roadmapping
Before we write production code we settle platform choice, MVP scope, compliance, and integration risk. Consulting is useful when you are choosing native versus React Native, estimating a 2026 budget, or deciding what must ship in v1 versus v2.
• Product and Technology Roadmapping:
Map features, architecture, platform choices, user flows, release phases, and delivery priorities around business goals.
• Risk and Opportunity Assessment:
Find gaps in usability, security, scalability, store policy, integrations, and performance before they slow the project.
AI-Powered iOS & Android Apps
We add on-device and cloud AI where it changes the product: camera analysis, recommendations, voice, document capture, and in-app copilots. Models stay behind your API or on-device runtimes so user data is not scattered across third-party tools.
• Intelligent User Experiences:
Add on-device ML, LLM APIs, camera intelligence, voice, and privacy-preserving prompts where they improve the product.
• AI-Driven Operations:
Use models for recommendations, document capture, and in-app copilots — the same approach behind products such as Bud Proof AI and Fluent Fox.
Legacy App Modernization
Older Objective-C, Java, or abandoned hybrid shells slow releases and fail new store rules. We modernize in stages: dependency upgrades, crash reduction, UI refresh, then module-by-module rewrites so users are not forced into a big-bang cutover.
• Architecture and Code Modernization:
Upgrade OS, SDKs, privacy manifests, and 64-bit support while replacing brittle networking and unmaintained plugins.
• Business Continuity-Led Migration:
Modernize in planned stages so users keep access while modules move to SwiftUI, Jetpack Compose, or a current backend.
Enterprise & API Integration
A native app is only as useful as the systems behind it. We connect iOS and Android clients to REST or GraphQL APIs, CRMs, ERPs, payment processors, identity providers, and custom Node.js or Python backends with auth, retries, and offline queues.
• API-First System Connectivity:
Build secure APIs, SSO, OAuth, and role-based mobile access so the app exchanges data reliably with internal systems.
• Unified Enterprise Workflows:
Keep login, reporting, and operational data in sync — including offline queues when the network is poor.
App Store Launch & Maintenance
Launch is not the end of native development. We monitor crashes, OS breaking changes, store policy updates, and conversion on listing pages, then ship patches and features on a cadence your users can trust.
• Release Trains:
Crashlytics, performance traces, TestFlight and Play tracks, and a cadence for OS updates after launch.
• Ongoing Support:
Retainer or sprint-based iOS and Android maintenance so store policy and device changes do not stall the product.
We design and engineer iPhone and iPad apps in Swift and SwiftUI, with UIKit where a mature codebase needs it. The work covers navigation, offline storage, push notifications, widgets, Apple Pay, and App Store submission — built to Apple Human Interface Guidelines so the product feels native, not ported.
• Scalable & Secure:
Build Swift and SwiftUI apps with Combine, Core Data / SwiftData, Keychain, and enterprise-ready privacy, data protection, and App Store compliance.
• Feature-Rich:
Ship widgets, Apple Pay, Face ID, TestFlight pipelines, App Store Connect listings, and privacy labels without a last-minute scramble.

Why Zupitrix
Why hire Zupitrix for iOS and Android development
A native app is a long-lived asset. You want a team that has released to stores, survived review, and planned the version after the version you are buying today.
Shipped products, not slide decks
Our iOS and Android work sits in production: wellness, education, AI camera, marketplace, and social products with real users. Architecture choices are ones we have already operated after launch, including crash rates, store reviews, and OS upgrades.
Native craft with a full product team
You are not hiring isolated Swift or Kotlin contractors. Design, mobile engineering, APIs, cloud, and QA sit in one delivery team so the iPhone app, Android app, and backend stay aligned.
Security and store compliance built in
Privacy manifests, Play Data safety, biometric auth, and encrypted storage are planned in discovery. That avoids last-minute App Store or Play rejections and expensive rewrites before launch.
A path after v1
We stay for analytics instrumentation, A/B tests, OS compatibility, and feature sprints. Native apps age with every Apple and Google release; maintenance is part of the engagement model, not an afterthought.
Building Future-Ready Apps with Emerging Technology Integration
We pick the stack that matches the product — native Swift and Kotlin when the OS matters, Flutter or React Native when one codebase is the better bet, then wire in cloud, APIs, and on-device or cloud AI where they change what the app can do.
The same delivery team covers iOS, Android, backends, and release tooling: REST and GraphQL, AWS, Azure, and GCP, plus Fastlane and GitHub Actions so TestFlight and Play tracks are not manual heroics after launch.
Technologies we use: Swift, Kotlin, Flutter, React Native, Jetpack Compose, Firebase, GraphQL, REST, AWS, Azure, GCP, AWS Bedrock, Docker, Kubernetes, Terraform, GitHub Actions, Python, Node.js, PostgreSQL, Fastlane.

How we work
How we build iOS and Android apps
The process is designed for store constraints and real devices. Discovery is short enough to start, and strict enough that engineering is not guessing screens in week six.
Discovery & platform choice
We map users, compliance, devices, and whether native, React Native, or a mix is the right investment. The output is a scoped MVP, risks, and a delivery plan.
UX, UI & clickable prototype
Flows are designed to each platform’s patterns — navigation, typography, and gestures — then prototyped so stakeholders can tap through before engineering ramps.
Architecture & API contracts
We define auth, offline rules, push, analytics, and the backend contract both apps will share, including environments and secrets handling.
Native engineering sprints
Swift and Kotlin teams ship in short iterations with PR review, automated checks, and device builds you can install from TestFlight or Play internal testing.
QA on real devices
Functional, regression, performance, and store-guideline testing on physical iPhones and Android devices — not only simulators — including poor network and background cases.
Store launch & hypercare
We submit listings, respond to review questions, watch crash-free sessions, and patch quickly in the first weeks after release.
