Which Accessory Turns Nintendo DS Into a Pedometer

This article outlines the specific hardware peripheral required to track fitness data on Nintendo’s handheld system. Readers will learn about the Nintendo DS Activity Pacer, its compatibility with specific console models, and the accompanying software needed to record walking steps accurately.

The accessory that transforms the Nintendo DS into a functional pedometer is the Nintendo DS Activity Pacer. This small hardware peripheral was designed to track the user’s physical movement and convert it into step counts within compatible software. It was primarily released to promote active gameplay and encourage users to engage in physical exercise while utilizing their handheld console for fitness tracking purposes.

To function correctly, the Activity Pacer must be inserted into the Game Boy Advance slot, known as Slot 2, located on the bottom of the original Nintendo DS and the Nintendo DS Lite. Because it requires this specific port, the accessory is not compatible with the Nintendo DSi, DSi XL, or any model in the Nintendo 3DS family, as those systems removed the legacy slot to reduce size. Users with the original hardware could clip the device onto their clothing or place it in a pocket to monitor daily activity levels.

The primary software title associated with this accessory is the rhythm fitness game Walk It Out! developed by Konami. When bundled with the game, the pedometer allowed players to unlock songs and content based on the number of steps they took in the real world. The device communicated with the game card to sync data, creating a bridge between physical walking and in-game progression. Although less common than standard fitness trackers today, this accessory remains a unique piece of hardware in the history of Nintendo’s experimental peripherals.
