Apps people keep

iOS, Android and web app development, APIs and portals designed for daily use.

We design and build iOS, Android and web apps, plus the APIs and portals behind them. Every release is tested on real devices, works when the signal drops and ships on a schedule you can plan around.

What you get

Everything it takes.

Six things included when we take this on — scoped to your business, never padded out.

01

iOS & Android apps

Native Swift and Kotlin when performance matters; Flutter or React Native when one codebase makes more sense. We'll explain the trade-off.

02

Progressive web apps

Installable web apps with offline support and push notifications, for when an app-store listing isn't worth the friction.

03

APIs & portals

Secure REST or GraphQL back-ends and admin portals so your operations team controls what the app shows.

04

Offline-first sync

Local storage and conflict-safe sync, so field teams and travellers keep working without a connection.

05

Security & compliance

Authentication, encryption, role-based access and data handling aligned with GDPR and regional data-protection law.

06

App-store release

Listings, screenshots, review guidelines and staged rollouts handled for you, including TestFlight and Play testing tracks.

How we approach it

Step by step.

Specific to app development — and at every step you'll see something real, not a status update.

  1. 01

    Product definition

    We define the one job the first version must do brilliantly and move everything else to a later release.

    What you seeA v1 scope, user stories and a release plan with dates.
  2. 02

    Prototype & test

    Interactive prototypes are tested with real users before we build, so we change screens, not code.

    What you seeA clickable prototype and a summary of where testers struggled.
  3. 03

    Build in sprints

    Two-week sprints deliver working features to test devices, with the API and admin built alongside.

    What you seeA fresh TestFlight or Play build every sprint, and a demo call.
  4. 04

    Harden & release

    Performance, accessibility, crash reporting and store submission, with a staged rollout to limit risk.

    What you seeThe app live in both stores and a crash-free-sessions dashboard.
  5. 05

    Iterate

    Analytics and user feedback shape the next release.

    What you seeA prioritised backlog and a steady monthly release rhythm.
Honest fit

Is this right for you?

Good fit if…

  • Your users need something on their phone every day — field staff, members, customers who reorder.
  • You need offline use, device features such as camera or GPS, or push notifications.
  • You're happy to launch a focused v1 and improve it, rather than build everything at once.

Not the right fit if…

  • A responsive website would do the job — and we'll tell you if that's the case.
  • Nobody on your side will own the app once it's launched.
Stack & platforms

Tools we trust.

What we typically use for app development. We'll always work with the tools you already own where they're the right fit.

Ways of working

How we work together.

Every project is scoped on its own terms — we'll agree the shape, the pace and the team with you before anything starts.

Most common here

Fixed-scope project

A defined deliverable, a timeline and a single agreed fee before we start. Changes go through a simple change note, never a surprise invoice.

Best forShipping a focused first version.

Monthly retainer

A standing team and a set number of hours or outcomes each month, reviewed together and adjusted as priorities shift.

Best forMaintenance, OS updates and support.

Sprint

One or two focused weeks on a single problem, with a clear goal on day one and a working result on the last day.

Best forOngoing roadmap with a stable team.
FAQ

Cross-platform (Flutter or React Native) suits most business apps and saves cost. Native wins for heavy graphics, advanced device features or when you want the most polished feel on one platform. We recommend per project, with reasons.

You do. Code lives in your repository and the apps are published under your own developer accounts from day one.

Yes. When it matters we design offline-first: data is stored on the device and synced safely when the connection returns, with conflicts handled rather than lost.

We design with Apple's and Google's review guidelines in mind and submit early builds for review. If something is flagged, we fix and resubmit — usually within a day or two.

OS updates, security patches, dependency upgrades, crash monitoring and small improvements. Most clients keep a monthly retainer so the app never falls behind a new iOS or Android release.
