Teams whose mobile app is the product, not a companion to it

The problem

Most agencies have a default answer before they have heard the requirements. Flutter for everything, or native for everything. The decision that actually matters — what happens at the third OS release, with a team you still have to hire for — never comes up.

Who this is for

  • Teams whose mobile app is the product, not a companion to it
  • Products that have to work offline, in the background, or deep in platform APIs
  • Teams inheriting a mobile codebase nobody has shipped from in a year

Who this is not for

  • Marketing sites wrapped in a WebView
  • Prototypes with no store submission planned

How it runs

  1. 01

    Pick the stack on evidence

    SwiftUI, Kotlin or Flutter, argued against your hiring plan, your platform-specific requirements and what the app must do offline. The reasoning is written down so the next person can disagree with it on the merits.

  2. 02

    Set up the release train first

    Signing, provisioning, store metadata and staged rollout land before the first feature. Retro-fitting a release process is the expensive way to learn it.

  3. 03

    Build the thin slice

    One real journey, on real devices, in TestFlight and internal testing — not a simulator demo.

  4. 04

    Harden the states nobody draws

    Offline behaviour, permission denials, deep links, background refresh, and what the app does when the network is slow rather than absent.

  5. 05

    Ship and hand over

    Both stores, crash and performance monitoring wired to an owner, and a release runbook your team can follow without us.

What you get

  • Stack decision record with the trade-offs written down
  • Signed builds and an automated release pipeline for both stores
  • Offline, permission and deep-link behaviour specified and tested
  • Crash and performance monitoring routed to an owner
  • Store listings, review submission and staged rollout
  • Release runbook your team can run without us

Native & Cross-Platform Mobile: questions we get asked

Should we build native or use Flutter?

It turns on three things: what the app must do that only the platform SDK exposes, who you can realistically hire, and how long the app has to live. Flutter earns its keep when the feature set is genuinely shared and the team is small; native wins when you are deep in platform capabilities — background processing, widgets, complex media — or when the two platforms diverge in the parts users care about.

How long does it take to get an app into the App Store and Play Store?

Weeks to the first real store build. Submission itself takes days, not months — but only if signing, provisioning and store metadata were set up at the start rather than in the week you wanted to launch.

Can you take over an existing mobile codebase?

Yes, and it starts with reading what is actually there rather than quoting a rewrite. Most inherited mobile apps need a working release pipeline and a dependency upgrade path more urgently than they need new architecture.

Do you handle store submission and review?

Yes — signing, provisioning, listings, review responses and staged rollout. You end with a documented release runbook, so the release after ours does not need us.

$ appine assess --fixed-fee

Two weeks. Fixed fee. You end with a decision, not a deck.

A system and codebase audit, a risk register ranked by severity, an engineering baseline, and an explicit recommendation — keep, harden, rebuild, or don't do it at all.

If the answer is “don't hire us,” we'll write that down too.
