Mobile apps your customers find useful
We can help you decide what your app really needs to do, test the idea with real users, and build it for iOS and Android, usually from one codebase. We can also help with the App Store and Google Play.
We can help if you are
- Businesses giving customers a faster way to order, book or track
- Teams replacing paper or spreadsheets with an app for staff in the field
- Founders turning an idea into a first version they can put in front of users
How we can help
Shaping the first version
We can help you choose what belongs in version one and test a clickable prototype before building.
iOS and Android
We can build for both platforms, usually from one shared codebase to save time.
Backend and admin
We can set up accounts, data and an admin panel so your team can manage the app.
Notifications and payments
We can add push notifications, in-app payments and links to the services you already use.
Store submission
We can help prepare your App Store and Google Play listings and guide you through review.
Improving over time
We can keep updating the app as operating systems change and users give feedback.


How we work together
- Step 1
Scope
We define the users, the core tasks and what success looks like, and turn that into a prioritised feature list.
- Step 2
Prototype
Clickable screens you can try on your own phone and show to customers before any code is written.
- Step 3
Build in rounds
Development in short cycles with test builds installed on your device, so you see progress every round.
- Step 4
Release and improve
Store submission and launch, then updates based on analytics and real user feedback.
Every project starts with a conversation
Tell us where things stand today and what you would like to change. We will ask a few questions, share how we could help, and give you an honest estimate. If we are not the right fit, we will say so.

Something else on your mind? Ask us directly.
Usually not. For most business apps we build both from one shared codebase, which saves time and keeps features in step. If your app needs deep platform features, we will tell you up front.
