App Development

Native and cross-platform apps built for the work people do away from a desk — and maintained past launch day, when the interesting problems start.

  • 45+ apps in the App Store and Play
  • 4.7 average store rating after launch
  • 99.9% crash-free session rate
OVERVIEW

What this actually involves

Shipping an app is the easy half. Keeping it fast, signed, compliant and working across four years of OS releases is the part that quietly costs money. We build with that second half in mind from the first commit.

Native and cross-platform apps, built and maintained past launch day.

  • Offline is a feature, not a bug

    Local-first data and sync, because crews and drivers lose signal constantly.

  • One codebase where it makes sense

    Cross-platform by default, native where the hardware genuinely demands it.

  • Releases that are not an event

    Automated builds, signing and store submission, so shipping is routine.

  • Supported past launch

    OS updates, store policy changes and crash triage handled as ongoing work.

PROBLEMS WE SOLVE

The things that usually go wrong

01

The app is useless without signal

Local storage with conflict-aware sync, so work continues and reconciles later.

02

Two codebases, two roadmaps, double the cost

One shared codebase with native modules only where they earn their place.

03

Every release is a fire drill

CI/CD with automated signing, beta tracks and staged rollout.

04

Nobody notices crashes until reviews drop

Crash reporting, performance monitoring and alerting wired in before launch.

CAPABILITIES

HOW WE WORK

From first call to handover, no surprises

  1. We agree what version one is

    The handful of things that matter on day one, and the ones that can wait. The price is based on that list.

  2. We design the screens first

    You see and click through the whole app before a line of code is written.

  3. We build in two-week blocks

    At the end of each block there is a working build on your own phone to try.

  4. We handle the app stores

    Developer accounts, listings, screenshots and the review process, including the rejections that come with it.

  5. We keep it working after launch

    Updates as phones and operating systems change, plus crash monitoring and the fixes that follow.

WHY TELCO

Four reasons clients stay

01

One accountable team

Strategy, design, engineering and support in one place. Nothing is handed to a third party.

02

Working software early

You see something real in weeks. Progress is demonstrated, not described.

03

Built to be handed over

Documented, tested and yours. No lock-in to us as a vendor.

04

Here since 1983

Four decades of keeping systems running, applied to the software layer too.

FREQUENTLY ASKED

App Development — common questions

An MVP sprint runs six to ten weeks from kickoff to a live product. A full build is usually three to six months depending on integrations. Maintenance retainers are ongoing. We give a range at proposal stage and a fixed date once scope is agreed — and if something slips, you hear it in that week’s update rather than at the end.

Fixed price for defined scope, a fixed fee for an MVP sprint, and a monthly rate for dedicated teams and support retainers. We do not bill hourly for delivery work — it rewards the wrong thing. Estimates come with the assumptions written down, so when something changes you can see exactly what moved.

You do, in full, from the first commit. Repositories are in your organisation, infrastructure is in your accounts, and design files are shared with your team. There is no license to renew and no dependency on us to keep operating. If you want to take the work in-house, we will help with the handover.

Two weeks of hypercare is included with every build — the team that shipped it stays on call for bugs and adjustments. After that most clients move to a support retainer covering monitoring, updates and a monthly allowance for changes. Some take it in-house instead, which is a perfectly good outcome.

Yes, and often that is the better arrangement. We can embed alongside your developers, take one workstream while they take another, or pick up an existing codebase. For inherited code we start with a short audit so both sides know what we are dealing with before committing to a timeline.

Small changes are absorbed. Anything that moves the date or the price gets written up as a change note with both impacts stated, and nothing starts until you approve it. The point is that there are no surprises at invoicing — you should always know what a decision costs before you make it.

For anything beyond a small, well-defined piece, yes. A paid discovery phase of one to two weeks produces a scope, an architecture outline and a costed plan — which you own and are free to take to another supplier. Quoting a complex build without it produces a number that is wrong in one direction or the other.

We agree the success measures before starting and instrument for them during the build, so the data exists from launch day rather than being retrofitted. That might be conversion rate, time saved per week, support ticket volume or crash-free sessions. If a number cannot be named up front, that is usually a sign the scope is not clear yet.
