Mobile App Development

Apps built for how phones get used on the job: one hand, poor signal, bright sun, gloves on. I ship them to both app stores and keep them there.

Two phones lying side by side showing the same job form, a caliper laid across them, and a pair of work gloves beside them.
The same app on both phones, built for gloves, one hand and poor signal.

What you get

  • One app, both platformsUnless there’s a good reason not to, and if there is, I’ll tell you what it costs.
  • Works offline by defaultField software that assumes there’s always a signal fails in the first basement.
  • App store submission handledAccounts, review, screenshots, the privacy questionnaire, and the first rejection.
  • Updates on your termsPush updates yourself, or have me do it, whichever you prefer.

With no signal, the app keeps taking entries and holds them on the phone. When the signal comes back, it sends them to the office one at a time.

    Custom

    More than one job, or hardware the phone has to drive.

    from $55,000 after discovery

    More than one job, hardware beyond camera and location, an existing system to fit, or a design of its own. Scoped in discovery, built in phases.

    • Several jobs, or several roles
    • Scanning, sensors, printing, wearables
    • Fits the systems you already run
    • Paid by phase

    Talk about Custom

  • Run plan · from $3,000 a year The infrastructure it runs on, kept up, backed up and watched. The server it runs on. Storage, and backups you can be restored from. Dependency and security updates. Monitoring, and someone who notices. Cancel at any renewal. You own the software either way.
  • That’s the starting price. A busier or more complex system costs more to run, and we agree on the number in writing along with the build, so it never comes as a surprise.
  • Not included: what you pay other companies. AI model and API keys, third-party licences and app subscriptions stay in your own accounts, at cost. I don’t mark them up.
  • The plan doesn’t include hours for changes. Each change gets its own price, agreed before I build it.
  • I’ll never take a percentage of what you sell: no royalties, no cut of transactions, no per-user fees for software you own.

When it’s the right choice

  • The work happens away from a desk: a site, a vehicle, a warehouse, a customer’s premises.
  • The phone’s own hardware matters: camera, location, scanning, notifications.
  • You’ve tried a mobile web page and it wasn’t enough.

When it isn’t

If a mobile-friendly web page would do the job, build that instead. It’s cheaper, it updates instantly, and nobody has to install anything.

Not sure it’s this one?

Describe the work in a sentence or two. You’ll see which of the services it reads as, where to start, and what that costs.
