Mobile App Development

Mobile App Development Services

Native and cross-platform mobile applications, built by a team that treats testing as part of development rather than an afterthought.

Start a Project All Services

ReleaseHaus designs and builds mobile applications for iOS and Android, from early technical planning through to a released, App Store and Google Play–ready product. Every build goes through the same structured QA process we use across all of our work, so functionality, compatibility and performance are validated continuously — not just before launch.

Whether you need a new application built from scratch or engineering support to take an existing product further, our mobile app development service combines hands-on development with real-device testing so issues are caught while they're still cheap to fix.

Who This Service Is For

This service is a fit if you're:

A founder or startup validating a new mobile product idea
A business replacing a legacy or agency-built app that's become hard to maintain
A team that needs mobile development capacity without hiring a full in-house team
A company that wants development and QA handled by the same team, not handed off between vendors

Problems This Solves

Apps that work in development but break on real devices your users actually carry
Features that ship untested and generate support tickets and bad reviews after release
Slow release cycles caused by bugs discovered late, or after the app is already live
No clear record of what was built, what was tested, and what's safe to ship

Outcomes

Benefits & expected results

A mobile application built with maintainable, well-structured code from the first commit

Fewer post-launch bugs, because testing happens throughout development, not only at the end

A documented QA trail for every release, so you know exactly what was verified

One team accountable for both the build and the quality of what ships

Scope

What's included

Technical planning and platform strategy (native vs. cross-platform)

UI implementation from your designs, or working with a design partner

Backend and API integration

Functional, UI, compatibility and regression testing throughout development

Release build preparation for the App Store and Google Play

Post-launch support and bug triage

How We Work

Our process for this service

Understand

Review requirements, target platforms and device coverage before writing code.

Build

Develop the application in incremental, testable pieces rather than one large release.

Test

Validate each piece with manual and automated testing as it's built.

Harden

Run full regression, compatibility and performance passes ahead of release.

Release

Prepare release builds and support submission to the App Store and Google Play.

This mirrors our full 8-step QA process, scoped to this service.

Why ReleaseHaus

Why we combine development and QA

We build and test under one roof because handoffs are where quality gets lost. When the same team writes the code and runs the tests, issues are caught in hours instead of surfacing weeks later in a separate QA cycle — and there's no ambiguity about who owns a bug once it's found.
