Services

Six disciplines. One team that owns the outcome.

From deciding what v1 actually is, through design and engineering, to sitting on the store submission and watching the crash graph afterwards.

Start a projectHow we engage
01

Product discovery & scoping

Before a line of code: what to build, what to cut, and what it will cost. You leave discovery with a scoped backlog and a fixed launch date — not an estimate range.

What you receive

  • Competitive teardown of 5–8 apps in your category
  • Prioritised feature set split into v1 / fast-follow / later
  • Clickable flow map of every screen in v1
  • Technical feasibility notes and platform risks
  • Fixed-scope proposal with timeline and cost
02

UI/UX & design system

Interfaces built on Material 3 and Apple Human Interface Guidelines, so the app feels native on each platform instead of a web page in a shell.

What you receive

  • Design system: type scale, colour, spacing, components
  • High-fidelity screens for every v1 flow
  • Interactive prototype you can tap through before build
  • Dark mode, dynamic type and RTL considered from day one
  • Motion spec for transitions and micro-interactions
03

Native & cross-platform engineering

Swift and Kotlin when the app lives or dies on performance. Flutter or React Native when one codebase on two stores is the right trade. We will tell you which you actually need.

What you receive

  • Typed, tested codebase in your Git organisation from day one
  • Offline-first data layer and graceful failure states
  • Accessibility: VoiceOver, TalkBack, contrast, touch targets
  • Automated builds on every merge, signed and distributable
  • Crash and performance monitoring wired before launch
04

Backend, APIs & cloud

The part users never see and never forgive. Authentication, data, payments, notifications and realtime — sized to your actual load, not a conference demo.

What you receive

  • REST or GraphQL APIs with versioning and documentation
  • Auth: email, social, phone OTP, biometric, SSO
  • Push notifications via APNs and FCM with delivery reporting
  • Payments: Stripe, in-app purchase and subscription handling
  • Infrastructure as code, staging and production environments
05

App Store & Play Store launch

Review rejection is the most common cause of a missed launch date, and almost all of it is preventable. We handle submission end to end.

What you receive

  • Store listings, keyword research and ASO copy
  • Screenshots, preview video and localised metadata
  • Privacy nutrition labels and Play Data Safety form
  • Pre-submission audit against both review guidelines
  • Staged rollout, review correspondence and appeals
06

Post-launch care & growth

Version 1 is where the work starts. OS releases, SDK deprecations, crash regressions and review replies do not pause because the project ended.

What you receive

  • Monthly OS, SDK and dependency upgrades
  • Crash-free rate monitoring with agreed thresholds
  • Analytics, funnels and retention instrumentation
  • A/B tested store listing and onboarding improvements
  • Roadmap sessions and prioritised release planning

Engagement models

Three ways to work with us.

Pick the one that matches where you are. You can move between them — most clients start with a sprint and continue into a build.

Product sprint

For an idea that needs a shape and a number.

Commercials
Fixed fee
Typical length
2–3 weeks

Best for: Founders validating scope before committing budget.

  • Competitive and technical teardown
  • Full v1 flow map and screen inventory
  • Prototype of the core journey
  • Fixed-scope build proposal and timeline
  • Yours to take to any studio, including not us
Scope a sprint
Most common

Launch build

Concept to two live store listings.

Commercials
Fixed scope
Typical length
10–20 weeks

Best for: Teams ready to build and ship a real v1.

  • Everything in the product sprint
  • Design system and every v1 screen
  • iOS and Android engineering
  • Backend, APIs and cloud infrastructure
  • Store submission on both platforms, handled
  • 30 days of post-launch fixes included

Embedded team

A standing product team without the hiring.

Commercials
Monthly retainer
Typical length
Rolling, 30-day notice

Best for: Live apps that need continuous delivery.

  • Dedicated engineers and a designer
  • Two-week release cadence
  • OS, SDK and dependency upgrades
  • Crash and performance monitoring against SLOs
  • Roadmap and prioritisation sessions
  • Scale up or down each month
Discuss a retainer

Every engagement starts with a call and a written scope. We quote against that scope, not against an hourly guess — so the number you approve is the number you pay.

Tooling

Boring technology, chosen on purpose.

We pick tools with long support horizons and large hiring pools, so your app is maintainable by someone other than us.
