After the update it’s miserable ### 1/5 — Slow to load *2019-09-20* Takes a solid 2 to 5 minutes to load. Insane. ### 1/5 — ‘Improved version apparently ‘ *2019-09-18* The app was working just fine before, but you just had to give the useless update and ruin it. ### 1/5 — Worssssst update ever *2019-08-24* It takes a lot of time to load the guidelines even if they are downloaded. App has become so slow that most of the times I end up opening the guidelines on my web browser. Please bring back the old interface. ### 1/5 — Update screwed the app! *2019-08-20* Keeps loading. If we download the guidelines it shows a blank page. Horrible update. Please rectify this. ### 1/5 — Worst ever update *2019-08-17* Though the content of NCCN guidelines are very good, it’s the recent update which has screwed the app. It keeps on loading and doesn’t open. Such a pathetic update for an 100mb app. ### 1/5 — Hate the smartphone app *2019-08-14, version 3.0.0* I was so much happier with the old non-smartphone app. This app is very slow, and although it’s very good at putting the “new version available” on the tumor type icons, I absolutely cannot figure out how to update the guidelines so that I actually have said new version. ### 1/5 — Disappointing *2019-08-03* Am not able to get to home page at all Also it won’t download the guidelines ### 1/5 — Unable to download guidelines *2019-08-01* I am not able to download any guidelines. Please help. Tried pressing download icon and selecting one guideline at a time. But no response ### 1/5 — Cannot log in *2019-03-27, version 2.0.0* Using my login that works on the website no longer works on the app. ### 1/5 — Not reasonable *2019-03-19, version 2.0.0* The guidelines are sometimes multiple versions out of date. The PDF files are not readable on a smart phone. This app is clearly just bolt on to the website and is not a priority project. The guidelines should be available clearly On the smart phone platform and they should be maintained and updated for patient safety and optimal cancer care. Good luck ### 1/5 — Buggy *2018-07-16, version 1.9.0* Info is all there but for something this important to every practicing Heme/Onc or trainee, really expect better than this. Hyperlinks don’t work well within content, crashes, fails to update. Customer service is excellent but they’re not working with a good product. ### 1/5 — Needs search function *2018-01-08, version 1.9.0* It takes forever to look for something as there is no search function And it has alot of bugs and kicks u out sometimes .Needs improvement. ## Most critical reviews (10 lowest-rated) ### 1/5 — Use *2025-07-23* Search option is not available facing difficulty ### 1/5 — It’s not showing the data properly *2024-06-05* Most of the data are blank. I need to go to website every time I need to see guidelines in ios. Please fix it. The format you are using is not working in ios ### 1/5 — Crash! *2022-02-13* Crashes all the time on iPhone. Blank pages coming up every time. ### 1/5 — Useless application *2022-01-27* Almost always leads to a blank page. Fails to open when I need it most. Takes forever to open those that actually work. Update guidelines function is the worst and takes hours irrespective of the number of guidelines downloaded. ### 1/5 — Crashing on opening every time on iPhone XR *2021-12-13* No update since long. I don’t think anybody is reading the feedback/ reviews ### 1/5 — Worst app *2020-09-03* What happened to you NCCN??? You don’t want any one to use your guidelines?? What an idea to have such a junk app! Kudos to app developer who made this app for not allowing anyone to follow new one and stick to old guidelines! ### 1/5 — Not even one star *2020-07-05* Too slow , every time it takes lot of time to open. if you have given command for update of guidelines than rest assured you won’t be able to use app for next couple of hours. ### 1/5 — Bad service *2020-02-27* Very bad service from this app Many times it doesn’t open at all Hope this problems will get resolve ### 1/5 — App closes immediately on its own *2019-12-05* Application closes on its own as soon as you open it. After update also the red new version available bar shown on many sites ### 1/5 — Latest update crashes *2019-12-05, version 3.2.0* Unable to use the app after the last update. It opens but crashes immediately. ## Most praised reviews (10 highest-rated) ### 5/5 — Helpful and Improved version *2024-10-15* This app provides all the detailed guidelines for clinical assessment and is extremely helpful. ### 5/5 — Improved version *2019-08-04* Could download the guidelines.. better than the previous version ### 5/5 — Must have for the med professional *2014-04-06, version 1.4* Easy to read up to date guidelines- use it all the time! Thanks for the app! ### 5/5 — Finally! *2014-01-14, version 1.1* Have been waiting for NCCN to migrate from iPad to the iPhone for a while now. Though, I would like to have the ability to highlight text within the guidelines. ### 5/5 — GREAT APP! *2013-12-20, version 1.0* This application has a great user interface and helps me access the guidelines I need. ### 3/5 — Annotation setting *2025-09-29* Unable to use the annotation setting on iPad ### 3/5 — App crashes often. *2019-02-25* This is a great resource but unfortunately it seems to crash quite often. ### 3/5 — Rotate. *2014-03-23* This would be great if it would rotate to landscape on iPhone. Too fiddly to use in portrait, so ends up untouched. ### 2/5 — Basically a pdf viewer *2019-01-07, version 1.9.0* I like the fact that the guidelines are easily categorized and look nice in the app. However, I for clinical use, I feel like I’d be be better off with my own annotated PDF version of each guideline. The app makes the guidelines easy to access and read, which is good for learning and studying but not great for ease of use in a visit. ### 2/5 — Better than nothing *2018-08-01, version 1.9.0* I’m a cancer genetic counselor and, and I’ve found this app most useful for quickly checking guidelines during tumor boards. Unfortunately, the app does have a habit of crashing and sometimes the guidelines remain out of date even after syncing. For example, the current version for the Hereditary Breast Cancer guidelines is 2.2019, but the app only has version 1.2018. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
