Full of racists


Facebook provides convenient API and many developers choose to use it when first publish their apps. You American think every Russian want your sick data? Posting rubbish and gross food everyday? Poor thing. Full of racist. Five star to support the developer. You don’t need to care about all the blame here. Be yourself and develop more apps like this!

Developer Response

Thank you so much, we really appreciate your support! We will do our best to improve the app and create more research-based tools for long and healthy life.



Are you serious? Do you pay attention? Even before the flack hit the fan I have never and will never log in with Facebook. Gave it 3 as a “maybe, I don’t know, never got to see it. Seriously, you must be off to think people will continue to log in with Facebook, or at sane people.

Developer Response

Thank you for your feedback, gt5! We were just so eager to launch beta version ASAP. Other login options are coming.

Works now.

It didn’t work initially, now it is letting me log in and seems to be working well. I can now reduce my 401k contributions based on my actual life expectancy and have more money for fun. (I’m kidding, I don’t put anything in my 401k).

Hello, Judge Wapner, please write us at hello@getgero.com if the problem remains!
