Weights is a clean workout log for lifters who want to record sets, reps, and strength without fighting the app. Start a routine, enter your numbers, and get back to training. Weights keeps your workouts organized so you can focus on the next set, not on tapping through clutter. WHY WEIGHTS Weights is built for real gym sessions. Use it as your workout tracker, gym log, lifting notebook, routine planner, and progress history in one focused app. Plan your training before you arrive, start a saved routine in seconds, log warm-up and working sets quickly, use recent performance to guide your next set, and review your history when you want to see what changed. FAST WORKOUT LOGGING - Log exercises, sets, weights, reps, and notes - Start predefined routines or build your own - Add custom exercises for your exact training style - Choose muscle groups with clear visual artwork - Track warm-up sets and working sets separately - Auto-fill weights and reps from your last session - Get Next Set guidance from recent workouts - Save equipment settings like seat height and depth - Switch between kg and lb units BUILT FOR PROGRESS Progress should be easy to understand. Weights helps you see training volume, workout history, best lifts, muscle focus, achievements, and strength changes over time. Use Next Set guidance to decide when to repeat, add a rep, or consider more weight. Review past sessions before a lift. Track personal records without digging through old notes. Follow activity and strength charts, open your history calendar, and unlock achievements as your training adds up. YOUR DATA STAYS USEFUL Export a clean ZIP package with a readable PDF progress report and CSV files for workout summaries, completed sets, and chart data. Use it for backup, deeper analysis, or reviewing your training outside the app. DESIGNED FOR IPHONE AND IPAD Weights is optimized for iPhone and includes a real iPad layout, not a stretched phone screen. Log workouts on the device that fits your training setup. BUILT TO STAY OUT OF THE WAY Your workout log should be fast, readable, and reliable.
