01 The problem

A Mobile App Is Not A Website In A Smaller Box

On the web, you control the runtime and you can ship a fix in minutes. On mobile you do not. Your code runs on a stranger's four-year-old phone, on a train, with 3% battery, and a fix takes a release and a review before anyone sees it. That gap is where most mobile budgets get spent twice.

  • It assumes the network works

    Built and tested on office wifi. In a lift or a basement it spins forever, or worse, silently loses what the user just typed.

    Offline failure
  • It was only ever tested on one phone

    Flawless on the developer's device. Elsewhere: clipped text, a keyboard covering the button, a layout that breaks on a notch.

    Fragmentation
  • Store review was an afterthought

    Missing privacy declarations, a login wall with no way in, a rejected permission. Weeks lost, and the launch date moves.

    Rejection
  • Nobody planned for year two

    New OS versions land every year and minimum SDKs rise. An unmaintained app quietly becomes one you cannot even update.

    Decay

On the web you can fix it in ten minutes.
On mobile, the fix ships when the store says so.

That is why we treat offline behaviour, device testing and release engineering as part of the build rather than as things to sort out near the end. On mobile, near the end is too late.

02 The first decision

Native Or Cross-Platform?

This is the question every mobile project starts with, and the honest answer is that it depends on what your app does, not on what is fashionable. We make the call with you before anything is built, because it is the one choice that is genuinely expensive to reverse.

Cross-platform

Right for most products

  • One codebase, both platforms, one team
  • Features land on iOS and Android together
  • Roughly one budget instead of two
  • Native modules where you actually need them
  • Fine for content, commerce, booking, dashboards
  • Cheaper to keep alive year after year
Fully native

Worth it when the app depends on the device

  • Heavy graphics, animation or real-time video
  • Continuous background location or sensors
  • Bluetooth, NFC or custom hardware
  • Demanding camera or on-device processing
  • Day-one support for brand new OS features
  • Costs more, so it needs a reason

And occasionally the right answer is neither. If what you need is a responsive web app that people reach from a browser, we will say so, because an app nobody installs is an expensive way to have a website. That conversation is free and it happens on the first call.

03 The scope

What We Actually Build

An app in the store, connected to a backend, with a release process your team can run. Not a prototype that still needs someone else to finish it.

01

The app itself

Everything the user touches, on every screen size.

Client
  • Screens and navigation architecture
  • Platform-native interaction patterns
  • Layouts from small phones to tablets
  • Dark mode and dynamic type
  • Accessibility and screen reader support
  • Deep links and app shortcuts
02

Data & offline

The part that decides whether it feels solid.

State
  • Local database and caching
  • Offline queueing and retry
  • Sync and conflict resolution
  • Secure storage for tokens and keys
  • Optimistic updates that roll back cleanly
  • Sensible states for slow and no connection
03

Backend & services

What the app talks to, designed for the app.

Server
  • APIs shaped around real screens
  • Accounts, sign-in and social login
  • Push notifications, targeted and scheduled
  • In-app purchases and subscriptions
  • Payments, maps and other integrations
  • Analytics and funnel events
04

Release & operations

Getting it live, and keeping it live.

Handover
  • Signing, certificates and provisioning
  • Store listings, screenshots and privacy forms
  • App review submission and any resubmission
  • Automated builds and beta distribution
  • Crash reporting and performance monitoring
  • Release runbook and team walkthrough
04 The process

How A Build Runs

You get the app on your own phone early, and you keep getting it every week after that. Nothing about the progress is theoretical.

  1. 01
    Week 0

    Discovery

    What the app does, who uses it and where they use it. Standing outdoors on bad signal is a different product from sitting at a desk, and it changes what we build.

  2. 02
    Week 1

    Platform & architecture

    Native or cross-platform, the offline model, the API contract and the data flow, decided and written down while changing your mind is still cheap.

  3. 03
    Week 2

    Build on your device

    An installable build in your hands as early as possible, then a new one every week through TestFlight and Play internal testing.

  4. 04
    Ongoing

    Feature by feature

    Each feature complete from screen to server before the next one starts, so the app is always in a state you could put in front of someone.

  5. 05
    Before launch

    Real devices & review prep

    Testing across old and new phones and OS versions, battery and memory checks, then the store paperwork: privacy, data safety, permissions and screenshots.

  6. 06
    Launch

    Submit, ship, watch

    We handle the submission and any rejection, then watch crash rates and performance in the first days live, when the real device mix finally shows up.

05 Who builds it

Engineers Who Have Been Through App Review Before

NoCubical is a small, senior studio. The people on your call are the people writing the app, and they have shipped through the store process enough times to know where it bites.

10+ years

Hands-on experience per engineer, across agencies, product companies and enterprises. No juniors learning on your budget.

Senior by default

Small by design. The person answering your questions in week one is still reachable in month six.

Built, shipped, maintained

Apps we launched and then kept running through years of OS releases, which is where you learn what really breaks. See how we work.

Published under your name

Apple Developer and Google Play accounts stay in your company's name, with the source in your repository. An app published under an agency account is genuinely painful to move later.

Your idea stays yours

We will sign a mutual Non-Disclosure Agreement any time you want one, at no cost. You can read the exact document we use before you ask for it.

Frequently Asked Questions

Native or cross-platform, which should we choose?

Cross-platform for most products, native when the app lives or dies on something platform-specific: heavy graphics, continuous background location, tight hardware or Bluetooth integration, or a demanding camera pipeline. We make the recommendation after we know what the app actually does, and we tell you what the trade-off costs either way.

Do you handle App Store and Google Play submission?

Yes, end to end. Developer accounts, signing certificates, provisioning, store listings, screenshots, privacy declarations, data safety forms and the review itself. If a submission is rejected we handle the response and the resubmission. Rejections are normal and usually fixable in days when someone has been through it before.

Who owns the developer accounts?

You do. The Apple Developer and Google Play accounts are registered to your company, not ours, and we work inside them with the access you grant. That matters more than it sounds: an app published under an agency account is genuinely difficult to move later.

Does the app need a backend as well?

Almost always, unless it is purely a local tool. Accounts, sync, notifications and anything shared between users need a server. We build that too, so the API is designed around what the app needs rather than handed over a wall. If you already have a backend, we integrate with it and tell you where it will need changes.

What happens when iOS or Android releases a new version?

Both platforms ship a major release every year, and both periodically raise the minimum SDK you are allowed to submit against. An app nobody maintains eventually stops being updatable and then stops being installable. We can hold a maintenance retainer that covers those upgrades, or hand your team the documentation to do it themselves.

Can you take over an app that already exists?

Yes. We review the codebase, the release setup and the store accounts first, then give you a written read on what is worth keeping and what will cost more to maintain than to replace. Taking over a partly finished app is common, and the honest answer is sometimes that the fastest route forward is not a rewrite.
