Mobile apps engineered for the real world.

iOS, Android and cross-platform builds that work offline, recover from bad networks and survive App Store review. We pick the right framework for the problem, not the framework on the homepage.

§ 01The problem

The problem we solve

Mobile is unforgiving. The network drops mid-request, the OS freezes your background work, the App Store rejects your seventh build over a copy change, and users uninstall the moment a screen feels wrong. We've shipped enough mobile apps to take all of that seriously — and to be honest with you about whether you actually need a native app or a great mobile web experience.

§ 02Capabilities

§ 06Process

How an engagement runs

  1. 01

    Framework decision

    Honest assessment of native vs cross-platform for your specific app. Written recommendation with trade-offs.

  2. 02

    Foundations

    Navigation, auth, storage, networking, CI, distribution — set up correctly so feature work is fast.

  3. 03

    Feature sprints

    Two-week sprints with TestFlight / internal track builds at the end of each.

  4. 04

    Submission & review

    App Store and Play Store submissions. We handle review responses and resubmissions.

  5. 05

    Operate

    Crash triage, analytics review, OTA updates, store optimization — for as long as you want us.

§ 07Engagement

How to engage

01

Fixed-Scope Build

10 — 20 weeks

From discovery to live in the App Store and Play Store. Senior delivery against fixed milestones.

02

Native Add-On

4 — 8 weeks

Adding a mobile experience to an existing web product, sharing as much code as the design permits.

03

Embedded Team

3 — 12 months

Long-term iteration with us inside your team, including release management.

§ 08Common questions

Frequently asked.

01Native, cross-platform or web?

We answer this in discovery. For most apps React Native gets you 95% of the way at half the cost; for performance-critical experiences (camera, AR, complex animations) we go native. We will tell you when you don't need a native app at all.

02Do you handle App Store review?

Yes — we manage submissions, review responses and resubmissions, including the eternally fun “your app needs more value” rejections.

03Can you take over an existing app?

Yes. We start with a paid audit, deliver a written assessment, and then either continue building or document a hand-back plan.

Have a problem worth solving well?

Tell us the outcome you want. We'll tell you what it takes — honestly, within a week, in writing.
