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. ### 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. ### 2/5 — Please fix the film *2022-10-01, version 1.5* None of the film works. Please fix it. ### 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!
