Overview
Trading Hammer is a crypto and forex trading journal I've built across iPhone, iPad, Mac and web. It helps traders log quickly, spot the habits costing them money and review their week — while keeping the native app private by default, including its AI.
The problem
Most trading journals collect more data than they interpret, and logging soon starts to feel like homework. Traders need fast reflection, trustworthy feedback and privacy for sensitive performance data.
My approach
I built the native experience with SwiftUI and SwiftData, using a shared analytics engine to surface patterns such as over-trading, broken rules and weak sessions. Supabase powers optional cross-device sync, while a Next.js web app brings the same journal and metrics to the browser.
The result
Live on the App Store and the web — a multi-platform product built on a privacy-first foundation for actionable trading insights.
