What is the purpose of the 3 icons located right next to each Noiseproof Summary?

There are 3 icons located right next to each Noiseproof Summary.

  • The left icon shows the subscription purchase status. If you haven`t purchased a subscription yet, the “Not Subscribed” icon will be displayed right next to all Noiseproof Summaries. If you`ve already purchased a subscription, the “Subscribed” icon will be displayed.
  • The center icon shows your Noiseproof Summary learning state: not started, in progress, or done.
  • The right icon shows whether the Noiseproof Summary has been saved in a favorites list.
