Health predisposition reports include reports that meet FDA requirements for Genetic Health Risks and wellness reports which are based on 23andMe research. Your ethnicity may affect the relevance of each report. Each Genetic Health Risk report describes if a person has variants associated with a higher risk of developing a disease, but does not describe their overall risk of developing the disease. The reports do not detect all variants. The reports are not intended to diagnose any disease, tell you about your current state of health, or for use in making medical decisions, including whether to take medication, or how much medication to take. This test is intended for use in adults.

Verdict
The clearest difference is in-app purchases: 23andMe at none against IronFast's 4. IronFast's advantage is ads (none vs shown) and update cadence (daily vs weekly). On price there is nothing between them.
