A Few Other Apps
Independent iOS and macOS apps built alongside client work. Position Sizer is live on the App Store now — the rest are still in development and testing via TestFlight, with App Store links appearing here as each one goes live. Hover a card (or tap, on mobile) for more detail.
Position Sizer
Limit losses, max your profit.
Given account size, risk percentage, entry price, and stop-loss price, it calculates exactly how many units to trade so a stop-out loses precisely the intended amount — built as a macOS menu bar app and iOS companion sharing one calculation core.
Jakt
Personal health tracking with deep HealthKit integration.
Tracks daily bio metrics — weight, pulse, blood pressure — alongside gym workouts and cardio activities, with read-only HealthKit sync from Apple Watch. Includes a home screen widget for at-a-glance stats and full JSON/CSV backup and restore.
Let Go
Guided meditation with live HealthKit vitals.
An animated mandala gently pulses through each session while a live breathing monitor and HealthKit integration track heart rate, HRV, SpO₂, and respiratory rate in real time — turning guided stillness into something you can actually see.
Wordinatrix
Real-time multiplayer crossword game.
Two players solve a crossword together in real time, in competitive or collaborative mode — competitive play only reveals an answer once fully solved correctly, so there's no peeking, while collaborative mode lets both players type at once. Supports FaceTime SharePlay for voice and video during play.
SoundTrip FX
Real-time audio effects processor.
Captures live microphone input and blends it with music playing from apps like Spotify, applying real-time effects — echo, feedback, pitch shift, reverb — through named scenes that can be layered together. No accounts, no network calls, everything happens on-device.
