MOBILE APP DEVELOPMENT

Build mobile products people return to.

A mobile app is judged in the first ten seconds and the tenth use. Stack18 builds native and cross-platform apps through the same governed pipeline as every other product — a real spec, real architecture, and production code you own.

Most mobile apps fail from unclear scope, not bad code — feature creep, no clear success metric, and a rushed release. Stack18 starts every mobile build with a signed PRD and a validated design system, then builds and ships production code you can maintain long after launch.

WHAT'S INCLUDED

What mobile app development with Stack18 includes.

From product definition to App Store and Play Store, with the source code and architecture handed to you.

Product discovery & PRD

User research and requirements distilled into a signed, scoped product specification.

UI/UX & prototyping

Native-feeling design systems and clickable prototypes validated before a line of code ships.

Native & cross-platform builds

iOS, Android, or cross-platform development chosen for your performance and budget needs.

Backend & API development

The backend services, APIs, and data layer your app depends on, built and documented.

QA across devices

Automated and device-matrix testing so the app performs consistently across OS versions.

App store deployment

Submission, release management, and monitoring setup for both major app stores.

HOW IT WORKS

The same governed pipeline, applied to mobile builds.

Every Stack18 engagement runs on one workflow — discovery, architecture & design, build & assure, deploy & operate — with a named human owner approving each gate.

01 · DISCOVER & DEFINE

Define the product

Turn user needs and business goals into a signed PRD and success metrics.

02 · ARCHITECT & DESIGN

Design the experience

Build the UI/UX system and technical architecture for the platform you're targeting.

03 · BUILD & ASSURE

Build & QA

Generate native or cross-platform code, tested across the device matrix that matters to you.

04 · DEPLOY & OPERATE

Ship & operate

Submit to app stores and monitor crash rates, performance, and usage post-launch.

WHY STACK18

Why companies choose Stack18 for mobile development.

Native-quality experience

Design and engineering built around platform conventions, not a generic cross-platform compromise.

Spec-driven, not scope creep

A signed PRD keeps the build accountable to what was agreed, with changes tracked and traced.

Tested before it ships

Automated testing across devices and OS versions catches issues before your users do.

Engagements start at $100K/yr.

Pricing depends on scope, number of products, and how much you want Stack18 to run versus own.

FAQ

Questions about Mobile App Development.

Native, React Native, or Flutter — which do you use?

It depends on your performance needs, timeline, and team's future maintenance plans. Architecture & design phase recommends the right approach for your specific product, not a default stack.

Do you handle App Store and Play Store submission?

Yes, deployment includes store listing preparation, submission, and release management for both platforms.

Can you add features to an app we already built?

Yes. Discovery reviews the existing codebase and architecture, and new features are built and integrated following the same governed process.
