Our official Instagram account is now @goodnotes.app!
We previously used @goodnotesapp on Instagram (and are trying to restore that account) as well.
We're dedicated to our user community and don't want to be offline for too long, so we're starting up this new one. So in short, yes, @goodnotes.app is our official account.
Remember to tag our new account @goodnotes.app in your photos on Instagram and follow us to stay connected!
