Margaret · Mobile App Studio
We design & build mobile apps.
Margaret is a mobile app developer and service provider. From first sketch to App Store launch, we craft fast, private, beautifully made iOS and Android apps — and look after them long after.
iOS & Android
Design + Development
Launch + Maintenance
What we do
Everything your app needs — under one roof.
Strategy, design, development, launch, and ongoing care. Work with one team across the entire lifecycle of your product.
Android development
Polished Kotlin apps that feel right on every device, screen size, and Android version.
Cross-platform
One codebase, both stores. Flutter and React Native when speed to market matters most.
UI/UX design
Clean, intentional interfaces and clickable prototypes that make your product a joy to use.
Backend & APIs
Reliable cloud, APIs, and Firebase integrations that scale smoothly as your users grow.
Launch & maintenance
App Store & Google Play submission, store optimization, updates, monitoring, and support.
How we work
A clear path from idea to launch.
No black boxes. You’ll know what’s happening at every stage — and see real progress along the way.
Discover
We start by understanding your goals, your users, and the scope — then map a clear, realistic plan.
Design
Wireframes and polished UI so you can see and feel the product before a line of code is written.
Build
Clean, well-tested code shipped in regular milestones, with you in the loop the whole way through.
Launch & beyond
We handle store submission, then support, monitor, and keep improving your app after release.
Our approach

Questions
Good to know.
What kinds of apps do you build?
Consumer and business apps for iOS and Android — native or cross-platform — from early-stage MVPs to mature products that need new features or a rebuild.
How much does an app cost?
It depends on scope and complexity. After a short discovery conversation we’ll send a clear, itemized estimate so there are no surprises. Get in touch for a quote.
How long does it take?
A focused MVP can take a few weeks; a larger product, a few months. We work in milestones so you see progress early and often.
Do you handle App Store submission?
Yes. We manage the full launch — App Store and Google Play setup, store listings and optimization, review, and release.
Who owns the code and IP?
You do. On final payment, ownership of the deliverables we create for your project transfers to you. See our Terms.
Do you offer ongoing maintenance?
Absolutely. We offer maintenance and support plans covering OS updates, monitoring, fixes, and new features after launch.
