JEFIT is a strength-training planner and tracker with a large exercise database, ready-made routines and an AI-powered adaptive plan on its paid tier. Isofit is a workout tracker that takes workouts by tap, typed line or voice, shows the muscles your sets reached on a body graph, and includes Atlas, an AI coach that can read your log. JEFIT is released and established. Isofit is released too, and newer. Available on the App Store and on the web. The short version: pick JEFIT if you want the largest built-in exercise database: JEFIT lists 1,400+ exercises; pick Isofit if you want plain-language logging and a coach built into the app.
