It is intuitive to use, has clear instructions (including drug doses and refractory options), and is frequently updated. A must-have for any doctor or medical student. ### 1/5 — Broken *2021-03-17, version 2.0* Previously good app, now no guidelines are visible on iOS 12.5, the app needs fixing ### 1/5 — App no longer working *2021-01-30, version 2.0* I have used this app for sometime and it has always worked well until recently (I haven't accessed it for approx 1 yr). None of the guidelines will load and I continually getting the whirling circle. I have deleted and downloaded the app several times, rebooted my phone to no avail. Totally useless to me now. Shame ### 1/5 — Not working *2020-11-16, version 2.0* App redownload and updated. Still not working. Urgent fix needed. ### 1/5 — App doesn’t work *2020-11-15, version 2.0* Stopped working completely after the latest update. Repeated trial to re-download/update not fixing it. ### 1/5 — Has never worked since covid update *2020-09-03, version 2.0* App constantly updates but shows no content. Have reloaded it 3 times with no success. Very disappointed as previously it worked very well and it is such an important source of information. ### 1/5 — Broken *2020-08-17, version 2.0* This app has been broken for a couple of months and still not been fixed despite contacting resus council through multiple channels. Really quite poor form given the clinical consequences that may ensue. ### 1/5 — No longer working post update *2020-07-24, version 2.0* Following recent update app no longer loads any of the guideline/flowcharts - rendering it useless. Similar issue as mentioned by others, getting stuck on a blank loading screen. Using iOS 11. Previous was an excellent app - Please fix! ### 1/5 — Not working since recent update *2020-05-29, version 2.0* Since the recent app-update the app does not display any content anymore. If i try to access my guidelines it just seems that the app is trying to load the content but does not get anywhere. Used the update button also with no effect. Dry sad as i felt this was a great app! ### 1/5 — Update 2.0 - app can’t be opened *2020-05-23, version 2.0* After updating version 2.0, the app can’t be opened- it says the app is no longer shared by you and pls buy it from App Store. So it’s a paid app now? ## Frequently asked questions about iResus ### What are the latest guidelines iResus follows? iResus is compliant with the Resuscitation Council UK Guidelines 2021.
