Zooming in portrait mode is barely bearable. ### 4/5 — Updates *2018-03-12, version 2.4.5* Not bad App, needs update with latest techniques. ### 3/5 — Helpful but buggy on an ipad! *2015-10-05, version 2.4.5* Has great much needed information for the rescuer but can not view full pages. App crashed twice... I didn't give it a third chance to crash. Go back to work on it CMC, then put it on the apple market when you have it right! ### 3/5 — Crashing *2014-10-15, version 2.4.2* On the latest version some of the links in the app don't work. It makes it crash. Please fix. ### 2/5 — Multiple glitches *2014-05-21, version 2.4.2* This is a great app when it is working well! If it was working right I would give it 5 stars. With the current version there are multiple glitches where you can not open all of the pages on the application without it kicking you out. You have to start the app over again and you will still never be able to get to those pages. ### 4/5 — No problems with this ap. loved the info! Thanks CMC! *2012-02-01, version 2.1.2* Loved all of the info! ### 5/5 — A most impressive pocket tool! *2012-01-31, version 2.1.2* I've always loved CMC's references books, and having them in electtronic format is fantastic!. There when I need them, rapidly accessed, and with everything in the original--plus searchability and convenience. Thank you, thank you, thank you! ### 5/5 — Great app *2011-12-24, version 2.1.2* This app is great! Really handy to have all the field guide info right on my phone, which is always with me. Thanks CMC! ### 5/5 — cmc rescue *2011-12-02, version 2.1.2* An amazing resource for rope access at a standard that is rarely seen in free apps. Clear images and simple to navigate. Not found any glitches yet. I think this might be the best app I have ever found. ### 5/5 — Amazing *2011-11-18, version 2.1.2* I'm a fire cadet and using this app helped a lot with the knots and testing! Great app! ### 5/5 — Even better! Not sure why the one bad review, works great, images are high quality too. Thanks CMC! *2011-10-17, version 2.1.2* The addition of the Confined Space Rescue Guide and the ability to add documents and photos (even videos) to my own notes and reference is huge. We are sharing this app department wide! Thanks again CMC, great work! ## Most critical reviews (10 lowest-rated) ### 1/5 — Faulty *2025-01-05, version 4.0.3* App crashed before it opened ### 1/5 — Unable to access *2024-07-05, version 4.0.1* Great update! But unable to go beyond first page after day 1. CMC, help! ### 1/5 — Was Great! *2024-06-14, version 4.0.0* After updating I wasn’t able to access! Not happy at all because I paid to get this app! ### 1/5 — Update *2014-01-06, version 2.3.1* I use this APP multiple times a week and with today's update I can no longer open the APP. If there is anything you guys can do to fix it would be great. ### 1/5 — oops *2014-01-06, version 2.3.1* new "upgrade" crashes on opening any of the items within the app... please help i needed my crutch today and it was not usable... ### 1/5 — Gatornumbers *2013-10-07, version 2.3* Could not find page all the time disappointed ### 1/5 — Not working *2013-02-13, version 2.3* App doesn't open. ### 1/5 — Sorely disappointed *2012-06-06, version 2.3* I was on a call and needed to know a knot so I opened the illustration page to learn how to tie it and the app crashed on the second page everytime. They should be paying you to download it until they fix the bugs and crashing ### 1/5 — Glitch *2012-02-17, version 2.1.2* This app is great. BUT it has a glitch where half the tabs disappear and are unavailable. They show up momentarily on the screen and then go away. It used to work awesome, now not as well. Hope you can fix it CMC ### 1/5 — Disappointed *2011-10-13, version 2.1.2* I was so excited about this app but have been sorely disappointed. It barely works (can rarely get into any of the pages) & the add-on pop up when you have a PDF open in any other program is really annoying. I wanted to like this and hope it will improve with a future update. ## Most praised reviews (10 highest-rated) ### 5/5 — Outstanding *2020-04-11, version 3.1.1* Outstanding quick reference for Fire Rescue Training ### 5/5 — Knot Knowledge *2015-08-04, version 2.4.5* This app is a must for Rescue workers and Boy Scouts.
