One team,the whole depth.

Design, engineering, release and maintenance under one roof. You brief once, and nothing gets lost in a handover between vendors.

  • 01

    Mobile app development

    Native and cross-platform builds for iOS and Android. One codebase where it pays, platform-native where it matters.

    • Swift / SwiftUI
    • Kotlin / Compose
    • React Native and Expo
    • Offline-first sync

  • 02

    Product design and UX

    Flows, wireframes and a design system your engineers can actually build from, specified down to the state.

    • Discovery workshops
    • Interaction design
    • Design systems
    • Prototyping

  • 03

    Backend and APIs

    The half of the app nobody sees. Typed APIs, real auth, sensible data models, infrastructure that scales quietly.

    • REST and GraphQL
    • Auth and permissions
    • Realtime and push
    • Cloud infrastructure

  • 04

    Store launch and compliance

    We handle submission the way people who have been rejected before handle submission: carefully, and once.

    • App Store review
    • Play Console rollout
    • Privacy manifests
    • Store assets and ASO

  • 05

    Quality and performance

    Automated tests, device labs and cold-start budgets. Shipping is easy; staying crash-free is the work.

    • Automated test suites
    • Device matrix QA
    • Crash and vitals monitoring
    • Performance budgets

  • 06

    Maintenance and growth

    OS releases every autumn, SDK deprecations all year. We keep shipped apps current and the roadmap moving.

    • OS version upgrades
    • Release management
    • Feature roadmaps
    • Analytics and experiments

01 FA · Engagements

Three ways towork with us.

Every engagement starts with a fixed-fee sounding week, so the estimate you get is built on measurements rather than guesses.

Zero to store

From $38k

A complete first release: design, build, QA and submission on both platforms.

  • 8 to 14 weeks
  • iOS and Android
  • Design system included
  • Store submission handled

Product partner

Monthly

An embedded squad shipping continuously against your roadmap.

  • Rolling two-week cycles
  • Dedicated team
  • Release management
  • Analytics reviews

Rescue and rebuild

From $12k

An audit of an app that stalled, then a plan and the hands to fix it.

  • Codebase audit
  • Performance triage
  • Store compliance fixes
  • Migration path

Indicative ranges for scoping conversations. Final pricing follows the sounding week, when the scope is measured rather than assumed.

02 FA · Delivery

What each cyclelooks like.

  1. 01

    Sound

    We drop the line. Goals, users, constraints and the systems you already run, measured before anything is drawn.

    Week 1
  2. 02

    Chart

    Flows, architecture and a scoped release plan. You approve a map, not a mood board.

    Weeks 2 to 3
  3. 03

    Build

    Two-week cycles, a real build on your device at the end of each one. No demo-ware, no surprise integration month.

    Weeks 4 to 10
  4. 04

    Harden

    Device-matrix QA, accessibility passes, crash and cold-start budgets enforced before we go near a store.

    Weeks 11 to 12
  5. 05

    Ship

    Submission, phased rollout and monitoring on day one. Then we plan the next version with the data the launch gave us.

    Release

03 FA · Tooling

Boring technology,deliberately.

We pick tools with long support windows and large hiring pools, so your codebase is still an asset when we are no longer on it.
