Promethease has been around for a while.
It is an oft-mentioned alternative for getting additional health information from DNA tests. It can import directly from 23andMe, you can upload your information to Promethease, or you could download the program and run it on your computer. It was faster to use the Promethease website, but there was a $5 cost, Running it from your computer could take several hours, but it was free. I have not tried it, but it mentions using AncestryDNA, Family Tree DNA, and other companies.
Like any health results, you should discuss the information with a trained medical professional. It does provide a lot of information.
I ran Promethease several months ago. I spent the $5 to speed up the process. In many cases, it looked at more SNPs for a condition than 23andMe. It did not try and predict my overall risk of getting a condition.
