How long does it take for a theme to be added to the feed

[kuroihoro]

I've been working on a theme on Prethemer, and I want to check out what I have done on my phone, but from what I've heard some things don't show up when you download and install it through quick install. In options, it's set to online and the show in feeds is checked, how long before it will show in the prethemer feed?
