Custom mobile apps built around real people.

BI.H Studio helps turn an idea into a useful iOS or Android app. We work across product strategy, UI/UX design, mobile app development, testing and launch.

What we do

Mobile app development, end to end

Whatever stage your idea is at, we can pick it up from there — a napkin sketch, a rough wireframe, or an app that already exists and needs to grow.

iOS

iPhone & iPad apps

Native Swift apps built for the App Store, tuned for performance and Apple's design guidelines.

Android

Android apps

Kotlin-based apps that run smoothly across the wide range of Android phones and tablets.

Cross-platform

One codebase, both stores

React Native and Flutter builds when speed to market matters as much as native feel.

Design

Product & UI/UX design

We shape the idea into screens people understand instantly — before a line of code is written.

Launch

App Store & Google Play setup

Store listings, screenshots and submission handled so your launch day isn't a scramble.

Support

Maintenance & growth

New OS versions, new features, new users — we keep the app running and moving forward.

Selected work

Mobile applications we've designed and built

Three applications we've created: a personal safety tool, a quiet digital library, and a visual trend tracker.

Common questions

Planning a mobile app?

Start with the users and the problem your app needs to solve. The right technology follows from that.

Do I need an iOS app, an Android app, or both?

That depends on where your audience is. We can plan a native iOS or Android build, or a cross-platform app that reaches both.

What happens before development starts?

We define the core features, map the user journey and design screens so the first version has a clear purpose and scope.

Can you improve an existing mobile app?

Yes. UI/UX updates, new features, performance work and ongoing maintenance can all be part of the project.

How do you prepare for launch?

Testing, store assets and submission planning help prepare an app for the Apple App Store and Google Play.

How an idea becomes an app

From a conversation to something you can hold

The same five stages, every time, so you always know what's happening with your app and when.

01

Discover the idea

We talk through what the app needs to do, for whom, and why it matters.

02

Design the screens

Wireframes and UI design turn the idea into something you can click through.

03

Build for iOS & Android

Our developers build the app natively or cross-platform, whichever fits the goal.

04

Launch it

We handle App Store and Google Play submission so launch day goes smoothly.

05

Grow it

Updates, new features and support keep the app improving after release.
