How does Ghost work with Feder?

  • Connect Ghost to Feder and it joins your Interest apps.
  • When you connect Ghost, Feder checks the connection straight away and shows Connected only when that check passes. If a reading cannot be taken later, Feder shows it as not read, never as zero.

Some numbers are too quiet to judge daily, such as a form filled in a few times a week. Until there is enough of your own history to judge a change, Feder says it is still learning and scores nothing, rather than guessing.

See whether you can trust the numbers in Ghost, one of your Interest apps. Feder only reads. It never changes anything in Ghost.
