01 FA · The name
Two words, oneworking method: fathomthe stack.
Fathom
Fathom — a nautical measure of depth, six feet of it, taken by dropping a weighted line until it finds the bottom. To fathom is to understand a thing all the way down.
Stack
Stack — every layer a product is made of: the interface, the state, the API, the data, the release pipeline, the store listing.
Together
Put the two together and you have our brief: understand the whole stack to the bottom, then build it so it holds.

Everything betweenan idea and a livestore listing.
Most studios hand off at a boundary — design to engineering, engineering to release. We own the whole depth, so nothing falls between two teams.
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
Flows, wireframes and a design system your engineers can actually build from, specified down to the state.
- Discovery workshops
- Interaction design
- Design systems
- Prototyping
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
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
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
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
03 FA · How we work
A twelve-week routefrom soundingto shipped.
Fixed cycles, a build on your device every two weeks, and no phase that ends in a document nobody reads.
- 01 / 05Week 1
Sound
We drop the line. Goals, users, constraints and the systems you already run, measured before anything is drawn.
- 02 / 05Weeks 2 to 3
Chart
Flows, architecture and a scoped release plan. You approve a map, not a mood board.
- 03 / 05Weeks 4 to 10
Build
Two-week cycles, a real build on your device at the end of each one. No demo-ware, no surprise integration month.
- 04 / 05Weeks 11 to 12
Harden
Device-matrix QA, accessibility passes, crash and cold-start budgets enforced before we go near a store.
- 05 / 05Release
Ship
Submission, phased rollout and monitoring on day one. Then we plan the next version with the data the launch gave us.
04 FA · Point of view
An app is only asgood as its slowestquery and its worsterror state.
Anyone can demo a happy path. We spend our time on the other ninety percent: dropped connections, expired tokens, low storage, cold starts, the review that comes back rejected. That is where users decide whether to keep your app.

A fathom is six feet, the unit sailors use to measure depth by dropping a weighted line until it finds the bottom. To fathom something is to understand it all the way down. The stack is every layer your product is made of. We understand the whole stack, to the bottom, before we build it.
Whichever your product needs. Cross-platform with React Native or Expo when the two apps are genuinely the same product and speed matters. Fully native Swift or Kotlin when you live in camera, background processing, wearables or heavy platform APIs. We tell you which one you are in during the first week, not after you have paid for the wrong one.
Most first releases land in eight to fourteen weeks including store submission. A focused single-platform MVP can be tighter; anything with payments, compliance or legacy integrations runs longer. You get a scoped plan with dates before we start building.
Yes, end to end: developer accounts, privacy manifests and data-safety forms, store assets, review responses and phased rollout. Rejections are usually a preparation problem, so we prepare.
You do, in full, from the first commit. Your repository, your cloud accounts, your store listings. We work inside your infrastructure wherever possible.
Often. We start with a paid audit of the codebase, the store standing and the crash data, then give you a plain assessment of whether it is worth continuing or rebuilding. Both answers happen.
