Google play store link includes non-tor/guardianproject apps
Under https://www.torproject.org/download/download.html.en#smartphone there is a link to https://play.google.com/store/search?q=guardianproject&so=1&c=apps which is searching for terms you could do https://play.google.com/store/apps/developer?id=The+Guardian+Project but that leaves out Orbot... so the solution may not be trivial, but the fact that there are two "security" type apps there already without relation to the Guardian Project or Tor seems like a bad omen.
