How much does mobile app development cost?

Our mobile app development starts at $10,000. Pricing scales with scope - a single-purpose app costs less than a full-featured platform, and shipping to both iOS and Android adds less than most people expect when built cross-platform. We scope your project precisely after a free discovery call.

What We Build

Every Type of Mobile App

Consumer, internal, or community. One platform or both. We scope to what your users actually need, not to a template.

Consumer Apps

Apps your customers open on purpose. Health, lifestyle, finance, social. Built for the first-week retention curve, not the demo.

Business & Enterprise

Internal tools, dashboards, field service apps. Put the workflow in your team's pocket instead of on a laptop back at the office.

Community & Membership

Schedules, bulletins, livestreams, push announcements, directories. The pattern behind St. Aloysius Connect, live on iOS and Android.

Is the intelligence the point?

If the app's core value is the AI itself (natural-language input, advisory chat, document understanding), start at AI-Powered Applications instead. That is where M+ Fitness and AmonHen live. Same team, different starting question.

Common Questions

Frequently Asked Questions

How much does iOS app development cost? +

Our iOS app development starts at $10,000. Pricing scales with scope - a simple utility app costs less than a full-featured platform. We scope your project precisely after a free discovery call.

How long does it take to build an iOS app? +

A typical app takes 8-16 weeks from kickoff to store submission, depending on complexity. We use sprint-based development with weekly demos so you see progress throughout.

Do I need an Apple Developer Account? +

Yes, you'll need an Apple Developer Account ($99/year) to publish on the App Store. We'll guide you through the setup and handle the submission process for you.

Can you update my existing iOS app? +

Yes. We take over maintenance and updates for existing iOS and Android apps, or rebuild them on modern Swift/SwiftUI or React Native. We assess your current codebase first and recommend the best path forward.

Do you build for Android too? +

Yes. St. Aloysius Connect ships on both iOS and Android from one cross-platform React Native and Expo codebase. When an app needs deep platform integration we go native in Swift; when it needs to reach both stores efficiently we go cross-platform. We recommend the right one during discovery.
