The smart equipment for fitness is now calculating calories and calories of the heart and sleep habits as well as every step taken by the device's user.

Fitness experts expect the use of these devices to increase and grow as they develop further. Jill, an analyst with the electronic magazine "PC Mag.com," said, "There have been two big changes with respect to the fitness devices since last year, a large number of them are now watching the heartbeat, and many of them have the smart clock feature." Smart phone applications, for example, showed text messages on the user's smartphone on his own fitness device. She added: "The expected Apple Hour, which will be announced in January, will be a smart hour and a fitness device at the same time, and the data on the heartbeat will appear in it."
