About this app

To understand how galaxies have formed, astronomers need your help to classify them according to their shapes. If you're quick, you may even be the first person to see the galaxies you're asked to classify. Images come from telescopes including Hubble and the Sloan Digital Sky Survey.

This app caches several subjects locally so you can classify even while offline and have the classifications automatically uploaded later.

This is an official Zooniverse app. To learn more about the Galaxy Zoo project and our science, visit http://www.galaxyzoo.org/

if I was rating this app on the concept alone, I would give it five stars. However, the app failed to load and stopped working. When I attempted to login, the app said that it was unable to connect to the server. As a result, I was not able to use the app shortly after installing it on 2019 June 23rd. I do like the fact that the app is designed to work offline after downloading data. I just hope that the next update will resolve its problems. Other reviews indicate that the app shows promise.

Like for others, the app won't download any data. Looking at the comments, this has been going on for at least 2 years! I have worked on the website before, but wanted an app for my tablet. I'm seriously disappointed because a) already explained and b) I get a lot of emails asking me to volunteer to work with other projects working under the auspices of Galaxy Zoo! It's around 1/week, on average. I would help, but you can't be a**ed to fix your own app!

It wouldn't download any pictures. kept getting an error message. Also it wouldn't let me register an account because of an error message saying my email was already in use. I tried 4 different email addresses and it always gave me the error message. unusable for me.
