Gyre is a free workout tracker that goes beyond sets and reps. It colors a real muscle map based on what you've actually trained recently (primary + secondary muscles), not a generic diagram. It auto-detects PRs and estimates your 1RM per exercise, and a weekly AI analysis reasons over your real training data (RIR/RPE trend, volume per muscle group, bodyweight trend) instead of giving generic advice. Routines remember your last weights and reps so you can start a session with one tap.
