CathSource

22 March 2026: To a person that has been a recipient of cardiac stents in the LAD five years ago, and is going back to the Cath Lab for possibly nor this year, this app, once I figured out the really bad UI was OK for what I was looking for. However, it has a really poorly designed user interface that makes it seem like it is dead upon arrival. Blank screens simply do not cut it and the menu icon is not obvious either. It was like looking at a book with a blank cover. You have to go to the TOC first to see anything. So info is there although not to the degree that a professional would probably expect given the other reviews. It also appears that the developer is totally unresponsive to the request for improvements, more info and video, and updates to bridge the gap between inadequate and adequate. I imagine it is totally frustrating for all who want to use the info.

Foundation of the app is there and it was likely worth the money at some point, just not now since the videos are apparently no longer supported. Disappointing from developers to leave on AppStore to continue to collect from users without continued support or a functional product.

Please update the app. The videos no longer show. Would be nice to be able to view the videos. Overall, a very good app and very educational. Just needs to be updated so the videos will play. Would be nice to also have videos of more blockages and other types of issues.
