Mobile app development services

Mobile app design and development services, from the first screen to the store listing — for one platform or both.

Third-Party Integrations

Push notifications, maps, payments and analytics SDKs — wired in and kept working through the OS updates that regularly break them.

Device & Release Testing

Every build gets checked on real hardware — crashes, memory, battery and the edge cases that never appear on a developer's phone.

App Store & Google Play Release

We handle submission, store listings and the review process — including the rejections, which happen to everyone and are mostly fixable in a day.

Ongoing Product Maintenance

iOS and Android ship new versions every year. Keeping an app compatible, updated and in the store is work that starts after launch, not a separate project.

iOS App Development

Native iOS builds in Swift when a product needs them — camera, sensors, background work and the platform features that don't survive a shared codebase.

Android App Development

Kotlin builds for the range Android actually ships on — from flagship phones to the three-year-old budget devices your users keep.

Cross-Platform Development

A single shared codebase for both platforms — usually one budget and one timeline instead of two, with native modules added where a feature needs them.

React Native Development

The framework we work in most. Mature, well-supported, and close enough to native that most users never tell — with a route to native code when they would.

Mobile App Design

Screens, flows and a design system built for thumbs — checked against Apple's and Google's guidelines before development starts, not after.

Our Process

Our mobile app development process

Five steps from the first call to a released app — including the one most timelines forget: getting through review.

Step 01

Discovery & Estimate

We map the features, the platforms and the constraints, then come back with scope, timeline and an estimate.

Step 02

Design & Prototype

Screens and flows first, as something you can tap through — before anyone writes the code behind them.

Step 03

Development

We build in sprints, and you get a working build on your own phone at the end of each one.

Step 04

Device Testing

Functional and performance checks on real iOS and Android hardware, across the OS versions your users are actually on.

Step 05

Store Release & Support

We prepare the listings, submit to both stores and handle review — then keep the app compatible as the platforms change.

Benefits

Why build your mobile app with FixIT

The parts of a mobile project that decide whether it launches on time — review, devices, and the OS versions you don't control.

Two Platforms, One Schedule

The second platform doesn't double the schedule — iOS and Android reach users within days of each other, not quarters.

Your Accounts, Your App

The App Store and Play Console accounts stay in your name. If we part ways, the app, the listings and the reviews stay with you.

Ready for the Next OS

iOS and Android ship a major version every year. We build so that the update is a scheduled task, not an emergency.

Fast on the Phone Your User Has

Most users aren't on this year's flagship. We build and test against older hardware and slower networks, where apps usually fall apart.

Fits the Product You Already Have

An app is rarely the whole product. We build it against your existing backend and data, not a parallel system to reconcile later.

You See the Numbers After Launch

Monitoring, dependency updates and the work that keeps a product from decaying are part of the build, not a project you commission later.

Frequently asked questions

The questions that come up on almost every app project — cost, platforms, stores and what happens after.

If you're building cross-platform, you don't have to choose: both ship together. If budget forces one, pick by audience — iOS users spend more on in-app purchases, Android has wider reach outside North America. We'll tell you which way your market points before you commit.
