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

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.

Plates offers direct and reverse weight input: dial in your desired numerical weight with the Digital Crown or alternatively tap plates to add them to the barbell. Both modes are always live which enables lighting quick input.

When lifting heavy on the barbell, it is important to properly warm-up to a working weight. To achieve this, the lifter commonly performs a series of warm-up sets with an increasing percentage of the working weight loaded on the barbell. Since it can become complicated to determine what configuration of plates match a warm-up percentage, Plates provides an intuitive warm-up percentage function to make this automatic.


Independent Watch App
Plates is designed and developed just for Apple Watch. It opens immediately and responds to your input fluidly without a tethered iPhone, which is great if you prefer working out with just your Apple Watch and headphones.

Digital Crown
Input your target working weight using the Digital Crown on your Apple Watch.

Weight Snapping
Dial in a target weight with the Digital Crown and Plates will snap to a valid plate configuration with a satisfying Taptic click.

Configurable Equipment
Force Touch the screen to configure the available plates at your gym and dial in your empty barbell weight. Plates uses this equipment to calculate valid barbell configurations. Plates supports metric and imperial weights and displays them using a standard color scheme.

Reverse Plate Calculation
Tap weight plates to quickly add to the barbell, then use the Digital Crown to make fine adjustments.

Warm-up Percentages
Tap the warm-up button to access common warm-up percentages. After you tap your desired warm-up percentage, Plates will reconfigure your barbell with reduced warm-up weight and remember your target weight. Use the Digital Crown to increase your warm-up percentage or clear the percentage to restore your working weight percentage.

Plate Standardizer
After tapping plates to load onto the barbell, you may end up with a non-standard set of plates on the bar. When this happens, a wand will appear next to the total weight; tap it and Plates will find the standard configuration for your selected weight (loading heaviest plates first).

Face Complications
Plates includes all types of face complications so you can add Plates to your workout-tailored watch face for quick access.

Needs Standard 1.25 plates

Love this, but...I need 1.25 plates, which are standard for Elieko and Rogue, at the very least. Hope y’all can add them!
