It is not what you think 😛
Subscribers to the virtual wife free service can choose from one of four virtual wives, who include a cute maid café waitress, a cool domineering analyst, a motherly nurse, and a fashionable nail artist, and even pick her name. Users then input their height, weight, and lifestyle habits.
In return, they receive 4 emails daily from their virtual wife that include nagging reminders not to engage in unhealthy habits and suggestions for reaching their ideal body weight—all in a tone of voice appropriate to the chosen character.
