Software development
Your product, in their pocket.
We design and build mobile apps for iOS and Android — from the first clickable prototype to the store listing — with the backend and APIs that keep them running.
The business challenge
A good idea isn’t a good app yet.
Apps compete for a place on someone’s phone. If the first few screens confuse people, they uninstall — and getting them back is hard.
- 01
Too many features at once
Trying to launch everything delays the release and hides the one feature people came for.
- 02
Two platforms, double the work
Separate iOS and Android teams can mean double the cost and features that drift apart.
- 03
The backend is an afterthought
An app without a reliable API, accounts and data behind it breaks the moment users arrive.
- 04
Store review surprises
Rejections over privacy, payments or metadata can push a launch back by weeks.
What we deliver
Everything between idea and app store.
We cover the app, the systems behind it and the work that keeps it improving after launch.
iOS app development
Apps for iPhone and iPad that follow Apple’s interface and privacy guidelines.
Android app development
Apps for the wide range of Android phones, released through Google Play.
Cross-platform apps
One shared codebase for iOS and Android when it suits the product and budget.
Mobile UI/UX design
Flows and screens designed for thumbs, small screens and short attention spans.
Backend & API integration
Accounts, data, notifications and payments, connected through a secure API.
Releases & feature updates
Store listings, review submissions, crash fixes and new features over time.
Key features & benefits
Decisions that make apps last.
- A focused first release
- You launch sooner with the core feature, then grow from real user feedback.
- Shared codebase where it fits
- One team ships to both platforms, so features stay in step.
- Prototype before build
- You test the flow on a real phone before paying for development.
- Store-ready from day one
- Privacy labels, screenshots and listings are prepared alongside the build.
Our process
From sketch to store listing.
Mobile work is staged so that you can hold the app in your hand early and often.
- 01
Product scope
We agree the core user, the main task and what the first version must include.
- 02
Prototype on device
Clickable screens you can try on your own phone and share with users.
- 03
App & API build
The app and its backend are built together, with test builds every week.
- 04
Testing & store prep
Device testing, store listings, screenshots and privacy details.
- 05
Release & updates
Submission to the stores, launch support and a plan for the next features.

Mobile Application Development: your questions.
Should we build native or cross-platform?
It depends on the features and budget. Cross-platform shares one codebase for iOS and Android; native makes sense for apps that lean heavily on device features. We recommend an approach after scoping.
Do you handle the App Store and Google Play submission?
Yes. We prepare the listings, screenshots and privacy details, submit the builds and handle any review feedback.
Can you build the backend too?
Yes. Most apps need accounts, a database and an API, and we build and host those alongside the app.
Can you take over an existing app?
Often, yes. We start with a code review to see what can be kept, what needs fixing and what it would cost to continue.
What happens after launch?
Apps need regular updates for new OS versions and devices. We offer ongoing plans for fixes, updates and new features.
