Rock-Solid Mobile Apps Development.

One codebase, both stores, published under your own developer accounts. We build the app and then hand you the release process, because the second release is the one that decides whether an app survives.

What we build, most requested first

Field and service apps

Job lists, photos, signatures and forms that keep working in a basement with no signal and sync when they surface.

Typical: offline is the default

Customer companion apps

Accounts, orders, bookings and notifications for the customers who already buy from you on the web.

Typical: one login across both

Internal operations apps

Stock counts, inspections and checklists, replacing the clipboard and the photo sent by message.

Typical: paper stops circulating

Marketplace and booking apps

Two-sided flows with payments, availability and the messaging that has to sit between them.

Typical: both sides in one build

Hardware and scanning

Barcodes, NFC, Bluetooth devices and printers: the parts a web app cannot reach.

Typical: no second device needed

Store rescues

An app stuck in review, crashing, or last released two years ago, made shippable again before anything new is added.

Typical: a release you can repeat

How a build runs, on your device from week two

Weeks 1—3

Flows and foundations

Screens agreed, project set up in your accounts, and a signed build installed on real devices.
Weeks 4—10

The core journey

The one thing the app exists to do, working end to end, on both platforms, in your hands weekly.
Weeks 11—17

Everything around it

Notifications, offline behaviour, permissions, edge cases and the states people actually hit.
Weeks 18—20

Submission and hand over

Store listings, review, phased rollout, crash reporting and a documented release you can run yourselves.

What you get

Published under your name.

The App Store and Play accounts are yours, the signing certificates are yours, and the release pipeline is documented and handed over. An app you cannot release without us is not an asset, and we do not build those.

The app on both stores

Submitted, reviewed and live under your own developer accounts.

One codebase

iOS and Android from the same source, so a fix is written once rather than twice.

A repeatable release

Build, sign and submit documented and automated, and run by your team before we leave.

Crash and usage reporting

What broke, on which device, and how often: visible without asking us.

Store assets and listings

Screenshots, descriptions and the privacy declarations both stores now require.

30 days of aftercare

Included in every package. The first real week of installs always finds something.

Talk about a retainer

Questions we get from new clients

Do we need separate iOS and Android builds?

Almost never. One codebase covers both for the great majority of apps, which halves the cost of every future change. Where a platform genuinely differs (widgets, deep hardware access) we write that part natively and say so in the quote.

Whose developer accounts do you publish under?

Yours. We work inside your App Store Connect and Play Console, and the signing certificates stay with you. Apps published under an agency account are extremely painful to move later, and we will not do it.

How long does store review take?

Usually one to three days for each platform, but it is not something anyone can promise. We submit early with a phased rollout, and the timeline above already assumes at least one rejection and resubmission.

What happens when iOS or Android changes?

Both platforms force an update roughly once a year, and an app that is not maintained stops being installable. That is what the retainer is for. If you would rather handle it internally, the release process is documented for exactly that reason.

Can it work without a connection?

Yes, and for field work it should. Offline-first means the app writes locally and reconciles when it reconnects, with your conflict rules. It is the single decision that most changes what a build costs, so we settle it in week one.

What do your people do on their phones today?

Describe the job and where it happens: a van, a warehouse, a customer’s kitchen. You get a fixed quote and a timeline within three working days, in your currency.
