Suggestions on indicating page has pull-to-refresh enabled

I love the ion-refresher, but have been finding that users don’t necessarily know that it’s there. Has anyone seen a good ui trick for indicating to the user that it’s available? I was thinking of just showing a bar or something at the top of the page for the first few seconds that it’s loaded with a label that it’s there or something, but thought someone might have a better idea :smiley:

Thanks!
