◆ 01 — Portfolio

Three apps. One studio.

Each product is built, designed and grown in-house. We eat our own cooking — and ship it on the App Store.

◆ 02 — Studio

A small team that does the whole thing.

We’re design, code, growth and ops under one roof. No subcontractors, no handoffs, no “that’s not my department”. We’ve been shipping consumer apps in the UK since 2019 — for ourselves and for clients who want a studio that ships, not pitches.

01

Product Design

Interaction, motion and identity. Designed in Figma, prototyped in code, validated with real users.

02

iOS & Android

Native Swift and Kotlin where it matters. React Native and Flutter when speed wins. Always crash-free.

03

Backend & Infra

Boring, reliable services on edge platforms. Realtime when needed, static when not.

04

Growth & ASO

Store listings, keyword research, paid acquisition and lifecycle. We obsess over the install funnel.

05

Monetisation

Subscriptions, IAP, ads — modeled and tested. We optimise for LTV, not vanity downloads.

06

Analytics

Privacy-first event design that actually drives decisions. No dashboards nobody opens.

◆ 03 — Process

From idea to App Store in 12 weeks.

Week 1–2

Discover

Audit the market, talk to users, define the wedge. We leave with a one-page product bet, not a 40-page deck.

Week 3–5

Design

Brand, flows, motion. Prototyped in TestFlight by the end. Real device, real hands, real edits.

Week 6–12

Build

Weekly internal releases, biweekly beta drops. Quality is a choice we make every commit.

Week 12+

Launch

Store listing, ASO baseline, soft launch in a test geo, then scale. We measure for 6 months minimum.

Got an idea?
Let’s ship it.

We take on a small handful of partner projects each year alongside our own apps. Tell us what you’re thinking — even a paragraph is enough.
