I’ve recently got some NOAA customized charts printed (from the downloaded PDFS) in waterproof format. These were printed by Paradise Cay. They had great e-mail/text/phone support.
My only wish was that the NOAA app would always add a compass rose to every custom chart. On the  large-scale custom charts that I created from North of Thunder Bay to South of it (at Alpena, MI, Lake Huron, USA) only two had a partial rose and the other two had no roses.
I believe that the NOAA app is in a trial phase and NOAA seems very interested in creating an app that users like - as they solicit feedback whenever you use the app. They also sent me an invitation to a zoom-type open discussion meeting with the goal of improving the app. Sadly the meeting was at a time when I couldn’t attend
