Read Trevor’s narration

FORGE started because I wanted to track seventy-five Hard, and every app I tried was either too complicated or too basic. So I built my own. Custom challenges from one to three hundred sixty-five days with your own rules, plus the seventy-five Hard template. Underneath that it's a full tracker: a workout builder with fifteen hundred exercises, a macro logger with a barcode scanner, progress photos, friends, and leaderboards. It syncs through Apple Health. React Native and Expo, and version two is live on the App Store.

The starting point

I wanted to track 75 Hard and every app I tried was either too complicated or too basic, and none were built by someone living it. So I built FORGE: custom challenges from 1 to 365 days with your own rules, plus a 75 Hard template with two workouts, the diet, a gallon of water, ten pages, a progress photo, and no alcohol.

What I built

Under the challenge layer it is a full tracker. A smart workout builder with six styles and 1,500 exercises with demo animations. A macro logger with a 300,000-item food database and barcode scanner. Water, reading, side-by-side progress photos, friends and weekly leaderboards, and streak reminders. It syncs through Apple Health with Apple Watch, Garmin, Fitbit, Strava, and Oura. React Native and Expo, RevenueCat for subscriptions, HealthKit for devices.

Where it landed

Version 2.0 is live on the App Store with a 30-day trial. I designed and built the product end to end, from challenge logic and health integrations to subscriptions and release.
