Native mobile apps
Swift and Kotlin, built to platform conventions rather than a lowest common denominator. Shipped to the stores, with the release process handled for you.

We build apps
after dark.
App Dev Room is a small room of app developers. iOS, Android and web — scoped, prototyped and shipped by the same people who write the code. No account managers, no relay race.

What we build ・ 制作領域
Four things, done properly.
We keep the list short on purpose. Everything here is built by the room — never subcontracted out and handed back over the wall.
Web applications
Dashboards, portals and internal tools that stay fast as they grow. Sensible stacks, deployed on infrastructure you can actually afford to run.
Working prototypes
A clickable, installable build in days — not a slide deck. The fastest way to find out whether the idea survives contact with real users.
Advice & rescue
Architecture reviews, code audits and second opinions — including projects already underway with another team that need steering back on course.
Selected work ・ 実績
Projects we've had a hand in.
Advisory
IG Website builder
We advised on the build for this creator website builder for Instagram users. An excellent and easy to use interface that will help creators build websites in minutes.

The room ・ チーム
A team, not a
supplier list.
Everyone who touches your project sits in the same room. That is the whole idea — the person who scoped it is the person who builds it, and the person who builds it is the person you talk to.
01
iOS engineering
Swift, SwiftUI, App Store releases and TestFlight builds.
02
Android engineering
Kotlin, Jetpack Compose, Play Console and staged rollouts.
03
Backend & web
APIs, data models and the web app that sits alongside the mobile one.
04
Product design
Flows, interface design and the prototype that proves it works.
05
Quality & release
Testing, store submissions and the unglamorous bit that gets it live.
Always on ・ 拠点
Three rooms.
One clock.
London, New York and Hong Kong. Between them the sun never sets on the room — there is always a team awake, building and on hand.

How it runs ・ 進め方
From idea to the store.
01
Scope
We work out what the first version actually needs to do, and argue you out of the half that can wait. You leave with a fixed shape and a real number.
02
Prototype
A build you can hold, in days. It is far cheaper to change your mind here than after the engineering has been written around the wrong assumption.
03
Build
Two-week cycles, a working build at the end of each one. You see progress on a device rather than in a status report.
04
Ship & keep it alive
Store submission, release management and the ongoing work of keeping an app healthy as the platforms move underneath it.
