Mobile App Development

Native iPhone and Android apps that feel inseparable from the device — built to ship fast and scale to millions.

Overview

Mobile App Development at Prixelo means picking the right build for what you're actually shipping, not defaulting to one stack for every client. Early-stage products and internal tools often move fastest as a single React Native or Flutter codebase deployed to both iOS and Android 30-40% faster than building each natively. Apps where performance, platform APIs, or a genuinely native feel aren't optional — anything targeting Apple Watch, Vision Pro, foldables, or Wear OS — get built natively instead, in Swift/SwiftUI and Kotlin/Jetpack Compose.

A lot of this work is a legacy app on an outdated stack that needs rebuilding, or a live app that needs continuous feature work without breaking what's already in production. We wire apps to Firebase or Supabase for auth, data, and push infrastructure so you're not maintaining custom backend plumbing alongside the mobile build itself, and we hand off code a future team — ours or yours — can actually extend.

Shipping doesn't end at the build. We handle submission to both the App Store and Google Play and the store-listing optimization that turns approval into installs. Timelines run 6-8 weeks for a focused MVP up to 6-9 months for enterprise-grade builds, priced from $5,000 for simple apps, $15,000 for medium complexity, and $50,000+ for enterprise-grade — scoped up front so there's no guessing mid-project.

How We Work

Our process

01

Platform Selection

We assess your product against native (Swift/SwiftUI, Kotlin/Jetpack Compose) versus cross-platform (React Native, Flutter) tradeoffs and lock a stack before writing a line of code.

02

Backend Setup

We stand up the data layer on Firebase or Supabase for auth, data, and push infrastructure, so the mobile build isn't blocked waiting on custom backend plumbing.

03

Build & Test

Engineers build natively in Swift/SwiftUI and Kotlin/Jetpack Compose, or share code via React Native/Flutter, with builds you can test on real devices throughout.

04

Launch & ASO

We submit to the App Store and Google Play, handle review feedback, and optimize listings and keywords so approval converts into installs, then stay on for updates.

FAQ

Frequently asked questions

Typically 3-6 months depending on complexity. A focused MVP can ship in 6-8 weeks; complex enterprise apps may take 6-9 months.
Cross-platform (React Native/Flutter) is the cost-effective default for most apps. We go native (Swift/Kotlin) for performance-critical, AR, or deeply hardware-integrated apps.
Simple apps start from $5,000, medium complexity from $15,000, and enterprise-grade apps from $50,000+.
Yes. We handle the entire submission and review process for both the Apple App Store and Google Play, plus post-launch updates.
Encryption in transit and at rest, secure auth (OAuth/JWT), and least-privilege API access by default. For regulated data we follow the relevant standard (HIPAA-aware patterns for health data, PCI scope minimization for payments).
We budget for 2-3 review rounds on the first submission, fix the flagged issue, and resubmit — this is included in the launch phase, not billed as extra work.

Mobile App Development

Mobile app development is the work of designing, building, testing, and publishing software that runs on iPhone and Android devices. At Prixelo, that means choosing between native builds in Swift/SwiftUI and Kotlin/Jetpack Compose, or a single cross-platform codebase in React Native or Flutter, based on what the product actually needs. The service suits startups shipping a first version, companies that need an internal or customer-facing app, and teams with a legacy app that needs rebuilding or ongoing feature work. Delivery covers platform selection, backend setup on Firebase or Supabase for auth, data, and push notifications, the app build itself with testing on real devices, and submission to the App Store and Google Play with store-listing optimization. A focused MVP typically takes 6-8 weeks, while enterprise-grade builds can take 6-9 months. Pricing starts from $5,000 for simple apps, $15,000 for medium complexity, and $50,000+ for enterprise-grade projects.

Questions buyers ask

What does mobile app development include?

It includes choosing the platform approach (native or cross-platform), setting up the backend for login, data, and push notifications, designing and building the app, and testing it on real devices. It also covers submitting the app to the Apple App Store and Google Play, handling review feedback, and optimizing the store listings. After launch, the work usually continues with updates, bug fixes, and new features as users and operating systems change.

What is the difference between native and cross-platform app development?

A native app is written separately for each platform, in Swift/SwiftUI for iOS and Kotlin/Jetpack Compose for Android, which gives full access to device features and platform behavior. A cross-platform app uses one shared codebase in React Native or Flutter to ship to both platforms. Cross-platform is usually quicker and cheaper to build and maintain; native is the better fit for performance-critical apps, AR, or apps that depend heavily on hardware.

Can an existing mobile app be rebuilt or modernized?

Yes. Many projects start with an app that runs on an outdated stack, is hard to update, or no longer meets store requirements. Modernization can mean a full rebuild on a current native or cross-platform stack, or a gradual approach that keeps the live app working while parts are replaced. The aim is code that a future team can read and extend, alongside continued feature work for current users.

What backend does a mobile app need?

Most apps need a backend for user accounts, stored data, file uploads, and push notifications. For many projects, a managed platform such as Firebase or Supabase covers these needs without building and hosting custom server infrastructure from scratch. That keeps the mobile build moving and reduces ongoing maintenance. Apps with complex business logic or existing company systems may also need custom APIs that connect the app to those systems.

What is App Store Optimization (ASO)?

App Store Optimization is the process of improving an app's store listing so more people who find it decide to install it. It covers the app name, subtitle, keywords, description, screenshots, and preview media on the Apple App Store and Google Play. ASO matters because store approval alone does not bring users; a clear, well-targeted listing helps the right people discover the app and understand what it does.
