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A lot of this work is a legacy app on an outdated stack that needs rebuilding, or a live app that needs continuous feature work without breaking what's already in production.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.
