I build small native apps, and ship them.

• stop-scroll Android · Kotlin

  Stop Scroll

  Measures the time you actually spend scrolling a feed, rather than the time the app sits open in front of you.

  • Separates active scrolling from idle time through an AccessibilityService
  • Different idle rules for list feeds (Reddit, YouTube) and full-screen video (TikTok, Reels, Shorts)
  • Week-over-week and month-over-month comparisons, with honest clipping of partial periods
  • Charts drawn directly on Canvas — no charting dependency

• converter-app Android · Kotlin

  Unit Converter

  Twenty categories of everyday conversion. Currently at v1.2.0, with the store listing and release notes kept in the repository alongside the code.

  • Length, mass, temperature, area, volume, speed, fuel economy, EV efficiency, pressure, power, pay, shoe and shirt sizing
  • Search matches unit names and symbols — psi, mpg, knot
  • Long-press a row to copy it; the last value in each category is remembered
  • Conversion tables covered by unit tests

• converter-ios iOS · Swift

  Unit Converter for iOS

  Twenty-one categories on iPhone and iPad, rebuilt in SwiftUI — and taken further than the Android build in a few places.

  • Pin a category, or a single conversion like Foot → Centimeter, to the top
  • Value fields read arithmetic — 12*3, 1½, 5'11"
  • A Clock whose units are cities, converted on any date so daylight saving holds
  • Nine Swift Testing suites over the calculator, clock, locale parsing and pins

• Bible_Promises_App Android · Java

  Promises

  A daily verse app carrying two public-domain translations, English and Malayalam.

  • Promise of the Day, browsing by topic, favourites and sharing
  • A daily notification at a time you pick, rescheduled across reboots
  • World English Bible and Malayalam സത്യവേദപുസ്തകം, both public domain
  • Light, dark and system themes, with a built-in feedback screen

• promises_ios iOS · Swift

  Promises for iOS

  The same app rebuilt natively in SwiftUI — a second implementation, not a port of the first.

  • Today's verse set over photography; swiping moves through the collection and changes the image
  • Serif, sans-serif or monospaced type at a size you set, with Dynamic Type honoured throughout
  • Favourites and notification scheduling via @AppStorage and observable stores
  • Shares its translation set with the Android build

• airport-terminal-app Android · Kotlin

  Airport Terminal

  Terminal and concourse layouts for 119 airports, from Atlanta's Plane Train concourses outward.

  • 119 airports with terminals, concourses and gate ranges in bundled JSON
  • An interactive terminal map drawn on a custom View
  • Links out to each airport's official map for the detail it can't carry

• simple-data-face Wear OS

  Simple Data Face

  A Wear OS watch face built on the declarative Watch Face Format, so the system renders it and the battery barely notices.

  • Seven complication slots, corner to corner
  • Editor options for time colour, complication colour and ring colour
  • An optional activity ring, and a toggle for complications in always-on

Nothing matches that filter. Choose another to see the rest.

• Two apps, each written twice

  Promises runs on Android in Java and on iOS in SwiftUI; Unit Converter runs on Android in Kotlin and on iOS in SwiftUI. Four apps, two ideas — each pair sharing its content and its conversion tables, and nothing else. The iOS builds use @AppStorage, observable stores and Dynamic Type rather than reproducing the Android structure in Swift.

• Drawing rather than depending

  Stop Scroll's charts and Airport Terminal's maps are drawn on Canvas in custom views. Both could have pulled in a library; drawing them directly kept the binaries small and left nothing to chase when the OS moves.

• Finished to the store, not the build

  Unit Converter is at v1.2.0 with its Play Store listing and per-version release notes versioned next to the code, conversion tables under unit tests, and a feedback screen wired up in the app itself.
