Barbell Calculator for Apple Watch

Plates is a powerful tool for the most important piece of strength training equipment in your gym: the barbell. Plates is designed for Apple Watch so you can compute barbell configurations quickly and accurately on your wrist using minimal input.

Dial in your target weight

Use the Digital Crown on your Apple Watch to select your target weight and Plates will compute the standard plate configuration to load on your barbell.

Select a warm-up percentage

Quickly select a warm-up percentage to apply to your target weight. Plates will automatically load the appropriate weights and remember your target weight when you are finished warming-up.

Tailor your equipment

Configure your plate inventory to match what is available in your gym. Plates supports imperial and metric barbells and plate weights.

Plates is an independent, native Apple Watch App so it doesn't require your iPhone to work and you can download Plates directly from your Apple Watch. It was designed and developed for Apple's brand new, modern User Interface: SwiftUI. This means Plates loads instantly and displays a fluid, responsive user interface tailored to the Apple Watch.
