Zero is a new app for tracking fasting created by Kevin Rose that is designed to help users keep to a regimented eating schedule. Rose says the inspiration for the app came from learning about the 16-hour fasting regime Hugh Jackman used to prepare to play Wolverine. Zero is available to download now from the iTunes App Store.
Zero tracks hours fasting as well as your nighttime eating by fetching your phones location and calculating local sunset time. For example, if the sun set at 6pm, and you began fasting at 8pm, Zero would automatically log two hours of nighttime eating.
