Based on the answers I gave, I’d say it’s fairly accurate. I gave the same answers for myself several times and it came up with the same number each time. Out of curiosity, I also put in the information for my 89 old grandmother and my two great aunts who are 92 and 99. Based on their current health, attitudes, mental condition and overall standards of living, I’d say the predictions for my grandmother and 99 year old aunt are accurate. I believe the estimate was too high for my 92 year old aunt based on the fact that she’s quite the pessimist plus has gone from mild dementia into full blown Alzheimer’s over the past few years. But overall, I think the app might be fairly accurate!
