What we build
What App Development includes
Senior-owned, AI-accelerated and integrated into your stack. Everything below sits inside your monthly capacity.
Native and cross-platform
Swift and Kotlin where it matters, React Native or Flutter where speed and shared code matter more. We recommend, you decide.
Backend and APIs
Authentication, payments, push notifications, offline sync and admin tooling built alongside the app, not by another vendor.
Store readiness
App Store and Google Play listings, screenshots, review compliance and phased releases handled for you.
Quality engineering
Automated UI tests, device-farm runs, crash monitoring and performance budgets in CI from the first sprint.
Design in the loop
Product designers working in the same sprint, using platform conventions so the app feels native to its users.
Growth hooks
Deep links, attribution, in-app events and onboarding experiments wired to your analytics from launch.
Process
How we run App Development
Capacity starts in days. Here is what the first weeks look like.
- 1
Day 0
Kickoff
A 30-minute call to agree goals, access and the first app priorities. You get a named senior lead and a shared channel the same day.
- 2
Week 1
First work ships
The first pull request, design or campaign is live within five UK business days. If it is not, week one is free.
- 3
Every week
Weekly visible progress
Continuous delivery into your repositories and tools, a written weekly update and always-on chat during UK hours.
- 4
Monthly
Review and flex
A strategic review where you reprioritise, scale capacity up or down, or pause. No change orders and no re-quoting.
Fit
When App Development is the right call
You need an MVP in the stores fast
A focused first version shipped in weeks, with the architecture to grow rather than be rewritten.
Your app has gone stale
An inherited codebase with OS warnings, slow releases and a shrinking team. We stabilise, then modernise.
Your web product needs a mobile companion
Shared APIs and design systems so the app and web experience stay in step.
Field or trades teams need offline tools
Job sheets, checklists, photos and signatures that work in a basement or on a roof, syncing when back online.
