Period Strength Tracker vs Grif

Train with your cycle, not against it. Your hormones shape how you feel, how you recover, and how you perform in the gym. Most fitness apps ignore this. Syne is built around it. Syne is the workout tracker designed for women who lift - and who want to understand why some training days feel effortless while others feel impossible. Log every session, track every personal record, and let your menstrual cycle guide your training across the entire month. TRAIN IN SYNC WITH YOUR CYCLE Every month your body moves through four hormonal phases - follicular, ovulatory, luteal, and menstrual - and each one brings different energy levels, strength potential, and recovery needs. Syne predicts your current cycle phase based on your personal data and automatically tags every workout you log. Over time you'll start to see your own patterns: which phases feel powerful, which feel heavy, and how to plan your training month around your biology rather than fighting against it. This isn't about training less. It's about training with more intention. LOG EVERY REP, SET, AND PERSONAL RECORD Track weight, reps, duration, or distance for any exercise. Syne remembers exactly what you lifted last time and pre-fills your sets as a starting suggestion - so you spend less time setting up and more time focused on your training. When you push past your personal best, Syne detects it automatically and highlights the new record right as you log the set. No digging through old sessions. No manual comparisons. Your progress is always visible. YOUR PERSONAL EXERCISE LIBRARY Every exercise you've ever logged is saved and organized in your personal library. Your most-used movements stay at the top so they're always easy to find, and your all-time bests are tracked automatically across every session - no manual input required. When you add a familiar exercise to a new workout, Syne pulls in the sets from your last session as a reference point. It's like having a training journal that actively helps you build on your previous work. BUILD WORKOUTS YOUR WAY Start from a blank slate and build any session you want. Add exercises, drag to reorder them, or hold one exercise over another to instantly create a superset. No templates to follow. No rigid structure. Just a flexible, fast builder that gets out of your way. A SPACE THAT FEELS GOOD TO USE Syne is designed to feel calm and encouraging - not stressful or gamified. Soft colors, clean layouts, no aggressive streak counters or guilt-trip notifications. Just a quiet, supportive space to show up, move, and feel good about it. Training should feel good, not like another thing you're failing at.
