What’s new

Complete UI Overhaul
We tore down the old interface and rebuilt it from the ground up so it looks and feels like a premium training tool.
• Dynamic Barbell Visualizer: Instantly see the exact plates you need to load for your next PR right on the screen.
• Custom Plate Inventory: The app now permanently saves your available equipment. Don't own 25kg reds? Tell the app once, and it will never suggest them again.
