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. -- Universe Observer, 2026-03-22 ### *---- "No longer supported" 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. -- 0987654321oh, 2022-12-29 ### *---- "Don’t bother with it." For some reason the videos are no longer loading. Look for a different app. -- VLJ9R, 2022-11-19 ### *---- "Not iPhone compatible" 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. -- peakyblinders 🥸, 2022-08-30 ### *---- "Videos won’t play my at on my iPhone 12." Do not pay for a non functional app -- SailordavidRN, 2022-05-25 ### *---- "Videos do not work" Very disappointing to pay for an app and not have the most useful aspect of it not work -- ygh245, 2021-10-15 ### *---- "Disappointing without cath videos" 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. -- gpm586, 2021-09-30 ### **--- "Lame" Animations will not load. Too bad seems to be an otherwise great app. -- furrmissile, 2021-08-05 ### *---- "Videos don’t work!!" 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 -- katem0913, 2021-07-23 ### ***-- "UPDATE!!!!" 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! -- Pinkcath3, 2021-04-14 [View all CathSource reviews and detailed analytics on AppTail](https://app.apptail.io/signup?utm_campaign=ai-crawl&utm_content=reviews) ## CathSource Discovered Keywords - cathsource ## Apps Similar to CathSource - [ASRA Coags](https://apptail.io/app/asra-coags-UdT/united-states) - [Eko Academy](https://apptail.io/app/eko-academy-NdX/united-states) - [Pocket ICU](https://apptail.io/app/pocket-icu-fwbb/united-states) - [Calculate by QxMD](https://apptail.io/app/calculate-by-qxmd-Mipb/united-states) - [STS Cardiothoracic Surgery](https://apptail.io/app/sts-cardiothoracic-surgery-Alsb/united-states) - [EchoGuide by ASE](https://apptail.io/app/echoguide-by-ase-eQxc/united-states) - [EchoRef](https://apptail.io/app/echoref-JBAc/united-states) - [HepCalc](https://apptail.io/app/hepcalc-YOHc/united-states) - [Cardiology Clinical Questions.](https://apptail.io/app/cardiology-clinical-questions-fhKc/united-states) - [STABLEize for HealthStream](https://apptail.io/app/stableize-for-healthstream-rkCj/united-states) ## CathSource Available In - [United States](https://apptail.io/app/cathsource-aFWd/united-states) - [Mexico](https://apptail.io/app/cathsource-aFWd/mexico) - [Switzerland](https://apptail.io/app/cathsource-aFWd/switzerland) - [Czechia](https://apptail.io/app/cathsource-aFWd/czechia) - [Algeria](https://apptail.io/app/cathsource-aFWd/algeria) - [Hungary](https://apptail.io/app/cathsource-aFWd/hungary) - [Azerbaijan](https://apptail.io/app/cathsource-aFWd/azerbaijan) - [Italy](https://apptail.io/app/cathsource-aFWd/italy) - [Kuwait](https://apptail.io/app/cathsource-aFWd/kuwait) - [Nepal](https://apptail.io/app/cathsource-aFWd/nepal) - [Peru](https://apptail.io/app/cathsource-aFWd/peru) - [Ireland](https://apptail.io/app/cathsource-aFWd/ireland) - [Belarus](https://apptail.io/app/cathsource-aFWd/belarus) --- ## About AppTail [AppTail](https://apptail.io) is a mobile app intelligence platform providing app analytics, ASO (App Store Optimization) tools, keyword tracking, competitor analysis, revenue estimates, and review monitoring for iOS App Store apps.
