It's fun to see how my daily movement affect to my health in the long term. I got a few of my coworkers to download the app too and now we all check in with each other daily to keep each other motivated.

Developer support on point

I voiced my concern below & the developers fixed the issue very timely. Now, I’m able to use the app as planned/described. I’m not done my first data collection experiment yet, but I already know I’m going to love this app.

This app sounded pretty nifty & a cool idea. I think this is where all the data tracking we’re doing these days is going. I have no problem logging in with Facebook. I tried to login via FB multiple times & the app wouldn’t move past the screen asking if I wanted to login with FB. I deleted & re-installed the app after I also restarted my phone. None of this worked. I have the iPhone X; maybe the app isn’t compatible with this phone...
Lemme know if you fix this issue & I’ll give one more try. Thanks!

Developer Response ,

Hi, Girlygirl192! Thank you for your feedback, we are so happy to hear that! The app is iPhone X compatible and should work now – we did had some technical issues yesterday. Please drop us an email at hello@getgero.com if the problem remains.

Great app based on powerful research

There are some things to tweak of course, especially with reliability of syncing the data, which is not always happening. That said, great to have it in App Store as research algorithms rarely made public.

Nonsense about Facebook login. I’m not clear how this affects data privacy of the app itself, not to mention “russian” being used as an argument.
