Hi Product Hunt! 👋 I'm David, the maker of Trainlog. As someone who trains regularly, I’ve always struggled to track the qualitative data of my workouts. My smartwatch tracks my heart rate, but it doesn't know if I slept poorly, if my left knee hurt, or if I was stressed. I tried writing in a journal after training, but typing with sweaty hands on a tiny keyboard is terrible UX. Friction is the enemy of consistency. So, I built Trainlog. It's a progressive web app (PWA) that removes the friction entirely. 🎙️ How it works: Finish your workout and hit record. Speak naturally for 15 seconds about how you felt. Our AI (Whisper + Llama 3) transcribes your voice and extracts structured data (fatigue, intensity, emotions). It builds a beautiful, searchable calendar history of your progress. 🛠️ The Tech Stack: I wanted this to feel native without maintaining 3 codebases. It's built with React 19, Firebase, Tailwind, and Vite PWA (with Web Push notifications finally working on iOS!). The code is completely open-source for my fellow devs! You can check the repo on my GitHub. I'd love to hear your feedback on the UX, the AI analysis, or the architecture. I'll be hanging out here all day to answer questions! 👇
