Once the desired output performance is reached, the custom profile is then saved to the memory of the tool and the connection to the smart phone is no longer necessary. The tools memory supports up to 4 custom profiles that can be easily accessed with the touch of a button on the tool. Your custom profiles are also saved in the cloud so that they can be accessed at any time.

The app will track all ONE-KEY compatible devices within 100 ft range of your phone. By building the functionality into the tool, not the battery, all devices are able to be tracked even if the battery is not charged or on the tool.
