Nickel Navigator is a free iPhone app developed by Rebelytics Research and Development Inc. It is designed to assist individuals on a low-nickel diet by providing them with valuable information about the nickel content in various foods.

With Nickel Navigator, users can access nickel data for over 800 foods from hundreds of national food studies and scientific articles. The app takes serving size into consideration, allowing users to make informed decisions about their food choices. Users can explore different food groups to identify which foods are highest and lowest in nickel, or they can simply search for a specific food.

One of the standout features of Nickel Navigator is the ability to drill down into the data for each food item. This allows users to understand how the nickel content of a particular food varies and also provides information about the reliability of the statistics for that food.

In addition to providing nickel data, the app also offers a food journal feature that allows users to estimate their daily nickel intake. This can be a valuable tool for those who need to closely monitor their nickel consumption.

It is important to note that Nickel Navigator is not intended to replace the advice of a medical professional. Users are encouraged to consult with a healthcare provider for personalized advice and allergy testing. The app is available in English only and does not require an internet connection.

For individuals on a low-nickel diet, Nickel Navigator provides a comprehensive support tool that can help them make informed food choices and manage their nickel intake effectively.
