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.
Define the product
Turn user needs and business goals into a signed PRD and success metrics.
Design the experience
Build the UI/UX system and technical architecture for the platform you're targeting.
Build & QA
Generate native or cross-platform code, tested across the device matrix that matters to you.
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.
