01 / Things I make

Apps

From an idea to something you can use.

Indie app

Dee

iOS & iPadOS · Android · watchOS

Muay Thai practice between classes.

My indie app for planning Muay Thai practice around your goals, time and equipment, then following guided rounds with voice, bell and haptic cues. Sync a plan to Apple Watch and train without your phone.

About the app Press kit

How I built it

  • SwiftUI
  • Kotlin
  • Jetpack Compose

Built with SwiftUI for iOS and Apple Watch, and Kotlin with Jetpack Compose for Android. A typed workout compiler and deterministic player keep session timing separate from the UI. iPhone and iPad use SwiftData with private CloudKit sync; Android uses Room and DataStore.

On iPhone, Android & Watch

Dee on iPhone: a shadowboxing round with a 2:45 timer, drill guidance and playback controls.

Dee on Android: a weekly training plan with kick drills and a button to start the next session.

Dee on Apple Watch: a heavy bag workout with a 2:53 timer, round two of five, and rest next.

A little about me

I’m Noam, a senior mobile engineer based in the UK, with over six years of experience. My day-to-day tools are Swift, SwiftUI and Kotlin Multiplatform.

I also make my own apps. Dee is one of them: a Muay Thai training companion for iPhone, iPad, Apple Watch and Android. Here, I keep my apps, engineering notes and conference talks in one place.
