04 — Mobile app development

One app, both stores, one team

Building for iPhone and Android used to mean two codebases, two teams and two sets of bugs. It does not any more. We build with React Native, so features land on both platforms at the same time and you pay for the work once.

The problem

What usually goes wrong

Two platforms, double the quotes

Traditional agencies quote iOS and Android as separate projects. You end up paying twice for the same feature and waiting while the second one catches up.

Six-month timelines for something unproven

You are asked to commit half a year and a large budget before anyone knows whether users want the thing. By launch, the assumptions the plan was based on have moved.

Nobody can tell you what the first version should contain

Everything feels essential in a workshop. Without someone cutting scope hard, the first release grows until it is late.

The app gets stuck at the store

The build is finished and then sits in review, rejected for a privacy label, a missing account-deletion route or a screenshot that breaks the rules.

How we solve it

Our approach

  1. 01
    One codebase, both platforms

    React Native with Expo. One team, one build pipeline, features shipping to iOS and Android together instead of drifting apart.

  2. 02
    We cut the first version to something real

    We work out the single thing the app has to do for a user to come back, build that properly, and leave the rest on a list. A small app that works beats a large one that is nearly ready.

  3. 03
    Store submission is part of the job

    Privacy labels, account deletion, age ratings, screenshots, review notes. We have been through it and we prepare for it during the build, not after.

  4. 04
    You get the code

    Your repository, your Apple and Google accounts, your app. If you want to take it elsewhere later, nothing stops you.

Every project runs through the same five steps — investigation, understanding the problem, development, testing, then launch and automation. See how we work.

What you get

Delivered at the end of the week

  • An app that runs on iPhone and Android
  • Your branding and your store listing
  • Submission to the App Store and Google Play handled
  • Source code and accounts in your name

Scope is agreed in writing before we start. If the work will not fit in a week, we say so before you pay anything.

Questions

Frequently asked

Is React Native as good as a native app?

For the overwhelming majority of apps, yes — and PawCal AI, our own product, is built this way. If you need heavy 3D, deep hardware access or sustained high-frame-rate graphics, native is the honest answer and we will tell you.

Who owns the Apple and Google developer accounts?

You do, in your company name. Publishing under an agency account is a trap that makes leaving expensive.

Do you keep working on it after launch?

If you want us to. See security and maintenance — otherwise you take the code and run it yourself.
