Oh you had problems accessing the about page? it should be pretty simple to load it.
There is no android app in the sense of an app you can load from the Google play store. The normal website adapts to phones so you just need to load it in a browser on your phone. However, I have not yet completed the extensive work needed to get the site to render properly and for authentication to work when using regular web browsers, so for now the only way to login on mobile is to use the browser that is built in to the hive keychain extension. if you open that up you will see a globe icon at the bottom - this is the browser. if you load ureka.social in that browser then should be able to login there just fine.
