What we do

One team for the whole app

Strategy, design, engineering, and launch under one roof - so nothing gets lost in translation between teams that have never met.

📱

Native iOS

Swift & SwiftUI apps that feel right at home on iPhone and iPad - smooth, fast, and with widgets that actually work.

🤖

Native Android

Kotlin & Jetpack Compose builds that respect Material design and every screen size your users bring along.

🎨

Product design

Interfaces that are obvious to use and a little bit delightful. We design with real content, not lorem ipsum.

We came to HG Mobile with a napkin sketch and walked away with a top-100 utility app. They shipped faster than our last two agencies combined - and actually explained things.

Got an idea? Let's connect it.

Tell us what you're building. We'll come back within two business days with honest thoughts and a rough plan - free.

Services

Everything your app needs, in one place

Pick the whole journey or just the part you're missing. Either way, you work with the people actually doing the work.

📱

Native iOS

Swift, SwiftUI & UIKit apps built to Apple's guidelines. Widgets, App Intents, live activities, StoreKit - the whole toolbox.

How you can hire us

Three ways to work together

💡 From scratch

You have an idea; we take it from blank canvas to launched app. Fixed scope, clear milestones, one price agreed up front.

Best for founders

🤝 Embedded team

Drop our designers and engineers into your team for a sprint or a season. You get senior firepower without the hiring.

Best for scale-ups

🩹 Rescue & revamp

Inherited a messy codebase or a stalled app? We audit it, tell you the truth, and get it back on the rails.

Best for existing apps

Not sure which you need?

That's normal. Tell us the situation and we'll point you to the shortest path - even if it isn't us.

About

A small studio that ships

We're the team you wished you'd hired the first time.

Our story

Founded by people who got tired of hand-offs

HG Mobile started in 2019 when a couple of app developers realized the best work happened when the designer, the engineer, and the person answering support emails were all in the same conversation. So we built a studio around that idea - deliberately small, deliberately senior.

We don't have account managers who relay messages to a team you never meet. When you work with HG Mobile, you talk to the people writing the Swift and pushing the pixels. It's faster, it's friendlier, and honestly it's more fun for everyone.

Today we're a remote-first team of seven, shipping apps that have been featured on the App Store, hit #1 in their categories, and - the part we're proudest of - kept their five-star ratings long after launch.

What we believe

Five things we won't compromise on

🔒

Privacy is a feature

We collect the least data possible and say so plainly. In a post-ATT world, respecting users is also good business.

Ship, then polish

Real feedback beats guesswork. We get a solid version into hands early and improve it with actual usage.

🧭

Honest by default

If a feature is a bad idea, we'll say so. If your timeline is unrealistic, you'll hear it from us first.

🧩

Details are the product

The haptic on a toggle, the empty state, the offline mode - the small stuff is what makes an app feel finished.

🌍

Built for everyone

Accessibility, localization, and small screens aren't afterthoughts. If it doesn't work for all users, it isn't done.

😄

Serious work, light hearts

We take the craft seriously and ourselves a lot less. Good apps come from teams that enjoy the build.

The team

Seven humans, one home screen

HM

Hana Moreau

Founder · iOS Lead

Ships Swift in her sleep. Owns three too many mechanical keyboards.

GA

Gabriel Antic

Co-founder · Android Lead

Compose evangelist. Believes every bug has feelings until proven otherwise.

SL

Sofia Lind

Design Lead

Turns "make it pop" into actual specs. Collects fonts like others collect stamps.

TO

Theo Okafor

Backend & Cloud

Keeps the servers boring, which is the highest compliment in this business.

MP

Mira Patel

Product & QA

Finds the one crash you'd have shipped. Then finds two more for good measure.

JR

Jonas Reyes

Growth & ASO

Speaks fluent App Store algorithm. Screenshots are his love language.

DV

Dan Vasquez

Studio & Clients

The reason your questions get answered before lunch. Powered by cold brew.

Process

From napkin to App Store

No mystery, no black box. Here's exactly how an app goes from your idea to a listing people download.

01

Discover

We dig into your idea, your users, and your market. You leave with a clear scope, a realistic timeline, and a fixed price - before anyone writes a line of code.

Week 1
02

Design

Flows, wireframes, then a clickable prototype you can actually tap. We iterate with you until it feels right, so there are no surprises later.

Weeks 2-3
03

Build

We develop in short cycles and send you a real, installable build every week. You watch your app grow instead of waiting for a big reveal.

Weeks 4-9
04

Polish & test

Real-device testing, edge cases, accessibility, and performance. This is where a good app becomes one people love. We sweat this part.

Week 10
05

Launch & grow

We handle the store submission, the screenshots, and the keywords - then stick around to fix, tune, and improve after real users arrive.

Week 11 & beyond
