Many people don't want to carry around journals to keep track of their calories. In 2005, Weight Watchers introduced a service where people could track their calories on Palm hand-held computers. This is a free service for people who are already paying the $12.95 monthly membership for the Weight Watchers online site.

Nokia introduced a phone in early 2005 (5140 model) which can be used as a 'virtual fitness coach'. It lets you plan your workout schedule depending on your goals. For example if you want to be able to run a marathon in ten months, it will give you a personalized weekly workout routine to help you meet that goal. Several other cell phone makers are also scrambling to offer similar options.
Samsung Electronics in Korea has even made a cellphone which lets you measure your body fat ratio by touching your finger to a sensor on the phone!
2006 will probably see a huge burst of innovations in the weight loss electronic tools market.
