What It Is
This is a health coach that remembers. Most fitness apps are just calendars with a sad graph — you log your workout, and then nothing happens. No feedback. No guidance. This is different. It’s an AI coach that actually looks at what you did and has an opinion on what you should do next.
What It Does
- Log your workouts — sets, reps, weight, exercise type
- Get feedback — the coach reads your history and tells you if you’re progressing or plateauing
- Ask questions — “Should I increase the weight?” “Am I overtraining?” — and get answers in plain language
- Set goals — track progress toward fitness targets over time
- Push notifications — reminders and updates so you don’t forget to log
How It Works
You log each workout as you do it. The AI coach reads your history, compares last week to today, and gives you feedback in plain language — no generic “drink more water” advice. It’s free to use and runs right here in your browser.
