App development

App Development

We build applications that survive real conditions: patchy mobile coverage, older devices, store review, and years of maintenance after launch. Scope is fixed after discovery, so you know what ships and when.

Discovery and prototype

Before code, we agree on the jobs the app must do, the screens required, and the data it needs. A clickable prototype settles disagreements early, when changes cost minutes instead of sprints.

Engineering and integration

Native or cross-platform depending on your requirements, with a documented API layer connecting to your existing systems — ERP, CRM, payments, logistics or bespoke databases. Offline behaviour and sync conflicts are designed, not discovered.

Store submission and release management

We handle App Store and Google Play listings, review responses, staged rollouts and crash monitoring. Release notes, versioning and rollback plans are standard so updates are routine rather than risky.

Post-launch improvement

Analytics and crash reporting feed a prioritised backlog. We ship small, frequent improvements against retention and conversion metrics instead of large annual rewrites.

What you get

  • Fixed-scope delivery after discovery
  • Offline-resilient architecture
  • Store submission handled end to end
  • Crash monitoring and staged rollouts

  2. Stage 2Core build in two-week increments with a demo at the end of each.
  3. Stage 3Hardening, accessibility, store submission and release.
  4. Stage 4Support, crash monitoring and a prioritised roadmap.

Commitments

What every engagement includes as standard

Response targets
P1 within 15 minutes, P2 within 1 business hour, P3 within 1 business day — measured and reported, not aspirational.
Reporting
A monthly service report covering tickets, uptime, patch state, backups and open risks, plus a quarterly strategy review.
Data residency
Australian workloads stay in Australian regions by default; UK, US and NZ clients are hosted in-region on request.
No lock-in
You own your domains, DNS, cloud tenancies and documentation. Exit assistance is written into every agreement.

App development questions, answered

  • Do we own the code?

    Yes. You own the source, the repositories and the infrastructure accounts. We document the build so another team could pick it up — we want you to stay because the work is good, not because you are locked in.

  • Can you take over an application someone else built?

    Frequently. We start with a technical audit covering dependencies, security, hosting and test coverage, then give you a prioritised plan with costs before touching anything.

  • Who supports the app after launch?

    My Global MSP takes on monitoring, patching and support under an agreed response schedule, so the people who built it and the people who run it are in the same group.

  • How do you price application work?

    Fixed scope and fixed price for defined builds, or a monthly capacity retainer for continuous product work. Either way you see the number before work begins.
