I see everyone showing cool pictures of it now I'm just sad its on pc not mobile
the mobile version are these last two download options
Gacha Redux Option 1
Gacha Redux Opt 2.apk
and just press download, as a precaution I recommend downloading the two links right away then you try one by one, one of them will take your cell phone
(if it appears that your device is not compatible unfortunately there is not much you can do)
