On the Go
Mobile Apps.
Design → Development → Deployment
iOS and Android, designed for the conditions phones are actually used in: one hand, poor signal, interrupted. Store submission, release management and crash triage included, because an app that ships is a process rather than an artifact.
Who this is for
Your product needs to work where the desk is not: on a shop floor, in a vehicle, in a hospital corridor, or simply on a sofa.
What you get
Artifacts, not activities.
- 01
The apps
Native or cross-platform, decided on your constraints rather than on our preference, with the reasoning written down.
- 02
Offline behaviour
What works without signal, what queues, and what the person sees when it cannot. Designed, not left to the framework.
- 03
Release pipeline
Signed builds, staged rollout, and a rollback that does not depend on store review.
- 04
Crash and performance baseline
Instrumented from the first build, with thresholds agreed before launch.
- 05
Store assets and submission
Listings, screenshots, privacy declarations, and the review responses when they come back.
How it runs
Every phase has a duration on it.
Weeks 1–2
Decide the platform
Native versus cross-platform, against your hiring plan, your device estate and the three features most likely to need platform APIs.
Weeks 3–10
Build for the conditions
Fortnightly TestFlight and internal-track builds. Tested on real devices on real networks, including the cheap Android everyone forgets.
Weeks 11–12
Submit and stage
Store submission, staged rollout, crash triage, and the first update shipped before the engagement ends so you have seen it done.
What it's built on
Named, so you can hire for it later.
We publish the stack because one of our refusals is building on something you cannot staff after we leave. If a choice here does not suit your hiring market, that is a conversation for week one, not a surprise in year two.

By design
Core flows work with no signal
These are the targets we work to on this kind of engagement, not averages from past ones. Measured outcomes carry a baseline, a period and the name of whoever measured them, and they live in See Impact in Action.
Ready to scope mobile apps?
It starts the same way every engagement does — four weeks, fixed scope, fixed price, and eight artifacts you keep whether or not you build with us.
