I've been working on this for about 3 years - teaching myself React (Next.js) and Javascript.
It’s designed for long-term barbell lifters and strength nerds who already track workouts in spreadsheets. All processing happens in the browser—no backend, no login, no data lock-in.
It has an openAI API "talk to your data" and a lifting coach feature.
Feedback very welcome—especially if you lift or track data in Google Sheets!
I personally am a 51 year old garage powerlifter. The app helps keep me motivated.
