Gainz — Workout Tracker

Gainz is a workout tracker built to help you progress every week without slowing down your training.

Log sets quickly with large weight and rep controls, optional RPE/RIR, and an auto rest timer. Follow structured strength and hypertrophy programs, review weekly training progress, and see muscle-volume status so every session has context.

Main features:

• Fast set logging for weight, reps, RPE, and RIR
• Bulk logging for repeated working sets
• Auto rest timer between sets
• Structured workout programs
• Weekly progress and catch-up planning
• Muscle-group volume and recovery status
• PR tracking and training history
• Offline logging with sync when you are back online

Gainz is for lifters who want less fiddling, clearer training decisions, and a better record of the work they are already doing.
