iOS and Android app development

From apps your team uses in the field to apps for your customers. We plan, build and publish iOS and Android apps, then keep them running and improving. We start by asking whether it should be an app at all, or whether the web or a LINE Mini App would serve better.

Who this is for

  • Field work and reporting should happen on a phone or tablet
  • You want a membership or booking app for your customers
  • You need device features such as the camera, location, Bluetooth or offline use
  • An existing app needs changes, or keeping up with OS updates
  • You can't decide between an app and the web

Common problems

Built, but not downloaded or used

An app designed without a clear user and moment of use gets installed, then never opened again.

Stuck in store review

App Store and Google Play requirements are left until the end, and release slips.

Falling behind OS updates

Yearly OS releases and changing store requirements go unhandled, and the app ages.

Paying twice for iOS and Android

Two separate code bases double the cost of building and maintaining the app.

What we deliver

Planning and requirements

We work out who uses the app, when, and which device features it needs, and whether an app, the web or a LINE Mini App fits best.

Design and build

Screens, the app itself, the server and admin tools. We choose native or cross-platform to suit the requirements.

Store release

Submission and review for the App Store and Google Play, including how to distribute: publicly or within your company.

Operation and improvement

OS updates, bug fixes, and measuring usage to keep improving.

How we work

From understanding your work to making the software stick and improving it — eight steps, with AI at every one. Hire us for all of it, or just the step you need.

Understand

Before deciding what to build, we learn how the work actually gets done. We measure where things stand today and agree the KPIs this software should move.

01 Discover, measure, define value 02 Requirements & RFP

Build

We build in short cycles and check each one against real work early, so the budget goes into what actually matters.

03 Design 04 Build 05 Test

Grow

Software only creates value once it's in use. We make it stick, measure what changed, and keep improving — until your own team can run it.

06 Launch, adopt & train 07 Run & maintain 08 Measure & improve

Why work with us

KPIs before code

We agree what success looks like before we start, and check it in numbers after launch.

Product people, not order-takers

We build, ship and run our own products, so we think like the owner — and we'll push back on features that won't pay off.

Deep in your business

We learn how the work really happens before deciding what to build — including whether to build at all.

In use, running smoothly

Rollout, training, maintenance and improvement are part of the job. Software nobody uses creates nothing.

You're never locked in

We leave the know-how with your team. Keep us on, or take it over — your choice.

How we measure the result

When work gets faster, the time saved is quickly filled by other work — and unless someone measures it, the value the software created simply disappears. So we measure the same process before and after, and you can see exactly what changed.

  • Time per field task or report
  • Errors from paper forms and re-keying
  • How many users keep using the app
  • Bookings or orders, and the effort to handle them

FOR ENGINEERS

For engineers

Choosing the technology

How much the app relies on device features, whether you need both iOS and Android, and who will maintain it decide between native and cross-platform development. On the server side we mostly use C#, ASP.NET Core and Azure.

Offline and sync

For places with poor signal, the app stores work on the device and syncs later. How simultaneous edits are handled is decided up front.

Authentication and data protection

We keep as little as possible on the device, and use OAuth 2.0 / OpenID Connect or your existing company sign-in.

How we use AI

AI speeds up design, implementation and testing, which keeps time and cost down. People review the code AI writes, and only code that passes its tests is released.

Deliverables and handover

  • All app and server source code
  • App Store and Google Play developer accounts in your company's name
  • Design documents, runbooks and store submission materials
  • Test code and test results
  • Training, if your team takes over operation

First step and contract options

Start by telling us who will use the app, and when. From there we begin in one of two ways.

Plan and choose the approach

We set out the features, compare an app with the web and a LINE Mini App, choose the technology, and give you a rough cost and schedule.

Try a prototype

We prototype the main screens and features, put them in front of real users, then move to full development.

Contract options

Fixed-scope contracts that deliver an agreed scope, or time-and-materials engagements for ongoing development. We do both.

Frequently asked questions

Is the web sometimes enough?

Yes. If the app hardly uses device features, or you want to avoid the install step, a web app or LINE Mini App can be the better choice. We help you decide that first.

Can you take over an app someone else built?

Yes. We study the code and how it works, document it, then take it over.
