Start with a free trial, then continue monthly or annually. COMMUNITY STANDARDS FastIQ has zero tolerance for objectionable content or abusive behaviour. Display names are filtered automatically, group fasts can only be hosted by people we have approved, and every profile, host and coach update can be reported or blocked from inside the app. Reports are reviewed within 24 hours and offending content and accounts are removed. Our Community Guidelines are in the app under Settings → Community, and at https://fastiq.fit/community-guidelines. FastIQ is an education and tracking tool, not medical advice. Talk to a qualified healthcare professional before starting any fasting or nutrition program, especially if you are pregnant, nursing, under 18, or managing a medical condition. Fasts longer than 48 hours carry real health risks and are not safe for everyone.
