Not on question on alcohol consumption, past medical issues, past surgery, are you a diabetic? Do you have heart conditions, etc. a total scam. ### 2/5 — Needs more data *2025-11-25, version 0.3* Without asking for health history I don’t see the value in this app. Sorry I paid for it. ### 1/5 — Is that it? *2025-11-16, version 0.3* Can’t believe I paid for this. ### 1/5 — Nothing! *2025-11-04, version 0.3* Age, height, weight, smoking history and how long did your family live. There is nothing helpful here. ### 1/5 — What happened to this calculator? *2025-10-17, version 0.3* This is advertised as one of the best calculators, asking 50 questions. It’s no longer free, which I get. But to pay for this abbreviated version is insulting. What happened to the supposedly robust set of questions? ### 1/5 — Not helpful *2025-10-03, version 0.3* Too few or detailed questions. How about never smoked or quit 30 years ago. Do you have any diseases like cancer, diabetes or genetic things. I think this is useless. ### 1/5 — Waste of money *2025-08-14, version 0.3* Doesn’t ask any questions about current health problems or concerns. Useless ### 1/5 — Shortened version is dumb *2025-07-29, version 0.3* This site used to have a comprehensive questionnaire that seemed to have enough rigor to be valid. This new version that I paid for is a joke by comparison. Wouldn’t have paid had I known it was so poor. ### 2/5 — Scam *2025-07-28, version 0.3* Can only use 2 time after purchase ### 1/5 — Waste of money! *2025-07-20, version 0.3* Expected a more detailed assessment. I should have noted that this is 10 years old BEFORE I started. ## Frequently asked questions about LivingTo100.com ### What does the LivingTo100.com app do?
