ExerSci

Show up. Look back. Train smarter.

Workout tracker meets AI fitness tools. Log every set, recall every weight, and let Claude or ChatGPT plan what comes next — all from a single workout log.

Show up

One bubble per workout. Your week, finally visible.

The schedule strip fills a bubble for every day you trained. Streaks become satisfying. Gaps become obvious. Most apps show you a calendar — ExerSci gives you a goal.

Look back

What did you lift last time? It's right there.

The "Previous" peek shows your reps, weight, distance, and duration from the last time you ran this exercise. Don't guess your starting weight — pick up exactly where you left off.

AI can analyze your sessions, build new plans for you directly in the app, and turn ExerSci into a real coaching loop.
