I build mobile apps and ship them.

Over ten years in software, five of them in mobile banking, payments and insurance. I run Ranova Labs, my own app studio, and build its apps with Claude Code.

Live on the App Store Sep 2026 · v1.1

Tally: Family Rewards

A parenting app where adults log a child's good and bad moments, each one moves a points balance, and the balance is spent on goals the child is working toward. Warm and simple on purpose.

  • Siri commands to log a moment or check stars. Logging needs Face ID or a passcode, so a child cannot talk the phone into awarding points.
  • iCloud sync, a Kid Mode with its own PIN, an App Lock, and backups as plain JSON.
  • Six languages, an optional Plus subscription through RevenueCat, and crash reporting.
  • In TestFlight now: a Home Screen widget, Control Center controls, and optional photo proof for chores.

Chalkline: Site Photo Log

A job-site camera for contractors. Every photo is stamped with the job, time, street address and GPS position, and a whole job exports as one PDF you can hand to a client, an adjuster or a lawyer. The app is a camera. The report is the product.

  • Each photo gets a SHA-256 fingerprint at capture. The report prints it, and the app shows whether a photo is verified, altered or has no fingerprint on record.
  • Stamps are applied on export, so originals stay untouched. Annotations are stored as vectors for the same reason.
  • Client sign-off on the device, an on-site banner when you arrive at a job, and a Shortcuts action for the Action button.
  • Twelve languages, free and Pro tiers with StoreKit 2, 30 tests, and no third-party dependencies.

Afterwards: Estate Checklist

When someone dies, nobody hands you a list. Afterwards is fifty-two steps for settling an estate in England and Wales, in the order they happen, with the deadlines that carry a penalty marked clearly. Nothing you enter leaves the phone.

  • The content is a separate project. Every claim carries a source link and a checked date, and a validator fails the build if one is missing.
  • Corrections reach people through a content feed that is checked against a SHA-256 hash before it touches a checklist, so a factual fix does not wait for App Review.
  • One-time purchase after three free sections, with more than a hundred automated tests.

Tally for Android

The Tally app ported to Kotlin and Jetpack Compose in a single session. It keeps the same seven-table data model, and its backup format is shared with iOS, so a family can move a backup between platforms. It is now in review for Google Play, with the same Tally Plus subscription through RevenueCat.

Mirrora: Screen Mirror for TV

An Android TV app that turns the TV into a screen-mirroring receiver for iPhone, iPad and Mac. It decodes the FairPlay-encrypted H.264 mirror stream in hardware and keeps the frames since the last keyframe, so the picture recovers instantly when the player reopens. Android has no ALAC decoder, so I wrote one in pure Java and tested it bit-exact against Apple's encoder.

It runs as a background service that starts with the TV, and falls back to its own mDNS responder on TVs whose system one never answers. Free and open source under the GPL, building on java-airplay.

How I work with Claude Code

I treat it as a fast pair, not a code printer. The speed comes from not having to leave the problem to look something up. The judgement still has to be mine.

  • Architecture first

    Decisions get written down where the next session will read them. Tally's Siri commands, widget and Control Center controls all sit on one App Intents layer instead of three separate ones.

  • Debugging on real devices

    A Siri command worked unlocked and failed on a locked phone. The cause was biometric authentication asked for from the wrong layer. The fix was the OS-level authentication policy, not a retry.

  • Tests where they earn it

    Two of Chalkline's tests are regressions for bugs found by driving the app, and Afterwards checks that its store product ID cannot drift from the StoreKit configuration.

  • Shipping is part of the job

    TestFlight pipelines, App Review notes, privacy and support pages, and the rejections that come from missing a small rule. The release work is in the repository, next to the code.
