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. ### 2/5 — Please fix the film *2022-10-01, version 1.5* None of the film works. Please fix it. ### 2/5 — Lame *2021-08-05, version 1.5* Animations will not load. Too bad seems to be an otherwise great app. ### 3/5 — UPDATE!!!! *2021-04-14, version 1.5* Please please I’m begging you to update this so the videos work again! I love this app for when I precept a new nurse to the cath lab - it’s the best app out there for exactly this use - the videos are key, please update! ### 1/5 — Disappointing *2021-04-11, version 1.5* The app simply doesn’t work, you are unable to see any videos or photos. ### 1/5 — Videos don’t play in iOS 14.4.4 *2021-04-02, version 1.5* Fix the issue ### 1/5 — Videos not working *2021-03-29, version 1.5* I got this app to have a visual for studying. Its not really helping me because the videos are not working. Please fix this! ### 3/5 — BLawsonRN *2020-12-09, version 1.5* 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. ### 1/5 — Great app when it works *2020-11-26, version 1.5* I used to use this app as a training aid, but the galleries don’t work anymore. I click on, for example, a normal left coronary artery and nothing plays. Please fix this. ### 4/5 — Good app, would prefer videos in addition *2018-12-26, version 1.5* Overall good would highly appreciate if there were more videos instead of the still films ### 1/5 — Waste of money *2014-10-28, version 1.2* No updates since 2011? Not a reassuring sign! This does not work for ios8, who knows when the last time it worked at all, do not waste your money on this. Very surprising because the other apps seem to work. ### 4/5 — CAD *2012-04-26, version 1.2* Love this app, use it all the time training new techs and nurses in the CCL. I would appreciate it if you would consider putting a couple CAD angiograms-lesions in as well. Do that and I'll give you 5 stars. ### 4/5 — CathSource is good for many levels *2011-06-23, version 1.2* Great App for many skill levels. Only suggestion would be to add labels to the angiogram films like there are on some of the still images. This would be helpful for those with only the basics...like those that may buy an App like this. ## Most critical reviews (10 lowest-rated) ### 1/5 — Videos’ problem *2023-08-16, version 1.5* Videos not playing , please fix it ### 1/5 — No longer supported *2022-12-29, version 1.5* The visuals are no longer get supported. It was initially a great app when everything worked. I’m just assuming the developers abandoned this app. ### 1/5 — Don’t bother with it. *2022-11-19, version 1.5* For some reason the videos are no longer loading. Look for a different app. ### 1/5 — Not iPhone compatible *2022-08-30, version 1.5* Annoyed that I have paid for this app when none of the pictures in the gallery will load. Do not recommend. Would like a refund. ### 1/5 — Videos won’t play my at on my iPhone 12. *2022-05-25, version 1.5* Do not pay for a non functional app ### 1/5 — Videos do not work *2021-10-15, version 1.5* Very disappointing to pay for an app and not have the most useful aspect of it not work ### 1/5 — Disappointing without cath videos *2021-09-30, version 1.5* 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. ### 1/5 — Videos not playing *2021-08-22, version 1.5* Please fix! Thank you ### 1/5 — Videos don’t work!! *2021-07-23, version 1.5* I wouldn’t purchase this if you are looking to actually watch the videos. There’s some interesting information and drawings but none of the videos work anymore. Update history shows it hasn’t been updated in five years ### 1/5 — Not updated *2021-06-19* This app was very useful when initially launched as the video loops made it very easy to learn and appreciate the coronary anatomy. Unfortunately these no longer run in the latest version of iOS making it futile. ## Most praised reviews (10 highest-rated) ### 5/5 — Please add Thebesian veins and vessels of Wearn *2014-01-19, version 1.2* Only if identified in further imaging. Thank you. ### 5/5 — Fantastic *2012-01-04* Fantastic educational app for anyone who works in a cardiac catheter lab. Highly recommended. ### 5/5 — Top of the line *2011-07-08, version 1.2* Wonderful teaching/learning tool. Explanations are clear and in-depth enough, video images wonderful.

Usefull for fellows in training as a reference. High quality images. Best $4 you'll spend. Worth every cent. ### 5/5 — Great Application *2011-04-11, version 1.1* Finally, an application for the Cath Lab. ### 5/5 — App at last *2011-03-02, version 1.0* Nice to see a Cath Lab app that is very useful.
