THYMOS is an offline-first workout tracker for serious strength training. Log your lifts fast, track real progress, and keep control of your training data. No account required. No social feed. No distractions during your workout. From barbells and dumbbells to machines, bodyweight exercises, and weighted calisthenics, THYMOS helps you record every set with less friction. WHY THYMOS? • Works offline • No account required • Fast set logging • Privacy-focused by design • No ads or social feed • Built for strength training, hypertrophy, powerlifting, and weighted calisthenics • Supports beginner, intermediate, and advanced training styles BUILT FOR REAL TRAINING THYMOS is designed around real training. Log sets, reps, weight, effort, and key workout details without fighting the app between sets. Track: • Warm-up sets • Working sets • Drop sets • Back-off sets • AMRAP sets • Failure sets • Supersets • Rest times • Bodyweight and external load The rest timer is built to support your session, not interrupt it. The plate calculator helps you load the bar faster. Bodyweight volume tracking gives a clearer picture of progress for calisthenics and weighted movements. SMART PROGRESSION GUIDANCE When your history supports it, THYMOS can suggest adding weight, repeating the current load, or returning lighter after a long break. Suggestions use completed sets, rep targets, effort, equipment, and training history across supported built-in and custom programs, plus saved templates. Nothing changes unless you tap Apply. WORKOUT PROGRAMS Choose from 26 expert-curated workout programs for different levels and goals. Choose from: • Beginner foundation programs • Upper/lower splits • Push/pull/legs programs • Dumbbell-only programs • Bodyweight training programs • Hybrid barbell and calisthenics programs • Weighted calisthenics programs Programs are built with progression, deloads, and practical training structure in mind. You can see why a program was selected, swap exercises, or change your plan when needed. EXERCISE LIBRARY THYMOS includes a comprehensive exercise library covering major muscle groups and movement patterns. • 430+ built-in exercises • Barbell, dumbbell, cable, machine, and bodyweight movements • Weighted pull-ups, weighted dips, and calisthenics variations • Form cues for each movement • Custom exercise creation WEIGHTED CALISTHENICS SUPPORT THYMOS treats weighted calisthenics as a first-class training style. Track bodyweight, external load, and total system weight for movements like weighted pull-ups and weighted dips. Follow progressions and build strength without forcing calisthenics into a generic lifting format. HONEST TRAINING ANALYTICS THYMOS focuses on useful, transparent training data. • Personal record tracking • Muscle group heatmap • Volume tracking by set type • Exercise-by-exercise progress • Clear 1RM estimates • Workout history and trends Measured data stays separate from estimated data, so your progress is easier to understand.

Verdict
The clearest difference is ads: Workout Tracker at none against GymBook's shown. Workout Tracker also leads on update cadence (every 3 days vs every 5 months) and iOS requirement (15.5 vs 17.0). On price, in-app purchases and device support there is nothing between them.
