Hi Hunters! 👋 I’m Jack. I’ve been lifting for over 10 years, but I’ve always struggled with consistency. The problem wasn't the workout; it was the friction. I was using MyFitnessPal for food, FitNotes for lifting, and other apps for sleep and a spreadsheet for weight. My data was everywhere. The only time I was consistent was when I hired a Personal Trainer who gave me one app to log everything, with daily and weekly check-ins that he would review on a daily/weekly basis. This is where my idea for RallyFit was born. The "Dad" Deadline: I started building RallyFit to replicate that "All-in-One" system. It had stops and starts, but then I found out I’m going to be a Dad in May 2026. This was my last chance to finish it. The Core Idea: The "Mirror" (Not AI Coaching) I didn’t want to create generic "AI Coaching"—I’m neither qualified nor is Gemini. Instead, I tapped into Cognitive Dissonance. RallyFit acts as a Mirror. It reflects your choices back to you based on facts. If you smash your goals, it celebrates. If you binge eat and miss sleep, it reflects that back to you without judgement. The Tech: Built with Next.js 16 + Firebase + Genkit. It's a PWA because I wanted desktop support for logging while I work and rapid deployment of new features. Being a Google Consultant as my main gig, I know how powerful PWA apps can be. I’m down 5kg using this everyday, with a goal to lose 15kg before baby is born. I’d love to hear your feedback! (Also, Dad tips are definitely needed! 🍼)
