QuitStart, the 100th mobile app to appear in USA.gov’s Apps Gallery, was created by the National Cancer Institute to help people stop smoking.

The mobile app provides help with tracking smoking cravings and moods and monitoring progress toward achieving smokefree milestones.

Quitstart is available for iOS devices and NCI describes it as a free smartphone app that can help track cravings and moods, monitor progress toward achieving smokefree milestones, identify smoking triggers, and upload personalized “pick me ups” and reminders to use during challenging times to help successfully become and stay smokefree.

Launched in July 2010, the Apps Gallery is the government’s primary citizen facing mobile gallery that features mobile websites and apps produced by the federal government for public audiences. There is also a Spanish language mobile gallery at apps.gobiernousa.gov.
