This is a fantastic app. The interface is easy to navigate and the layered images are helpful. As a regional anaesthetist I recommend it freely for those learning RA and for quick knowledge checks in time-pressed situations.

Fantastic app

Such a great app. Use it daily in work. Every anaesthetist should have it.

Huge fan of this app while in CRNA school! There is not any other educational content I’ve found that has the views that we will see as anesthetists

Great resource but buggy

Love this app when it works. Everytime you use it, it has to log you in. I have a very poor internet connection at my facility which makes this app unreliable. You should be able to use this app w/o needing to be connected, would give 5 star rating if this was the case.

Hi kbmountain, Thanks for taking the time to write a review. Please make sure you have the latest version. The app should work without an internet connection, with wifi off, or even in flight mode. If you leave the app running in the background it should reopen immediately. If you just close the app and do not sign out it should reopen within a couple of seconds. You should only have to sign in again if you sign out of the app. We have had a few technical issues over the first few months this year. They should all now be fixed. If you continue to have trouble please email us at ansomf@gmail.com so we can help further. kind regards AnSo

Now fixed

Love AnSo as a resource, I have the pro version and it’s a great day to day resource. Thanks for continuing to update and add new content to this wonderful app.

Currently broken?

Love AnSo as a resource, I have the pro version and it’s a great day to day resource. However I think this app has recently broken - can’t get past the loading data initial stage. Please fix! No contact information on your website.

Auto update needs fix

Was previously more functional despite less content. Now it gets stuck auto updating which isn’t always feasible in theatre

Thanks Shanah's intoxicant for the feedback. We will look at making the auto update an optional feature. kind regards AnSo.

Most recent update February 2026

Unfortunately seems like the app is broke again with this recent update. Missing files on every single block. I love this app so I’m hopeful a fix is coming soon!

Update: fixed! Works perfectly.

Hi Slyguy13, Sorry the app is letting you down currently. We are aware of the widespread problem. Our coders have been working hard to identify the cause and develop a fix. The fix is currently undergoing testing. Hopefully they will finish testing today/tomorrow and then it gets submitted to Apple and Google for review ( usually this takes another 24 hours), then released into the stores in a staged manner. So bottom line is if you have missing content problems the fix is probably still 2-3 days away. If you have a different problem please email us at ansomf@gmail.com. Sorry for the inconvenience this is causing you. Thanks for your patience while we get a fix to you. Kind regards AnSo

Just so slow

Makes you log in every time you open. Then takes ages to load new data. Constantly updating data causing lag in the app. Still can only use landscape. Very frustrating when you need to check something quickly in a busy clinical day. Just overall very poor execution for the price; the free one is much better or use another paid alternative IMO.

Thanks 54r45 for the useful feedback. If you do not sign out of the app, just close it, you should not have to sign in again with next use, it should just open. We are aware of time pressures in a busy operating theatre and are working to minimise the time it spends checking for updates to speed the reopening. We strive to keep the cost to a minimum and intend to make it free for Plan A blocks later this year with the subscription for the rest of the content. It works in landscape only to maximise the size of the US images as we feel they are too small to be useful in portrait. Thanks for taking time to give feedback. We will continue to work on these issues. Kind regards, AnSo.

App has no content

Paid for upgrade and when opened shows ‘missing content’ under all tabs. Don’t know how to get a refund!

Hi bongomoor, The app will just be called AnSo from now on to be consistent with the android version. It is the same app it is just no longer called pro. There is only one version. Sorry if you are affected by the current failure to load content bug. A fix has been developed and is undergoing testing. It should be released via the store in the next few days. Sorry for any inconvenience this may have caused you. kind regards AnSo

Improvement needed

It’s quite shocking how bad the last few updates have been. A once essential app has been rendered almost unusable.
My recent experience:
- Constantly having to re-sign in
- App claiming I don’t have a subscription
- Images not loading, last major update appeared to delete stored images despite them not seeming to have been changed with the update
- Long loading screens and still no viable options for offline-only or poor data reception zones. If the app isn’t instantly ready to use even when network connectivity it unfortunately is useless.
Unless it changes rapidly I’m afraid I won’t renew my subscription which is a shame.

Hi berio579, Thanks for your fair feedback. It has been a disappointing month. We have been working had to fix the issues and a new fix is now in testing. It will hopefully get to you in a few days and the app will then be back to being useful. Sorry for the inconvenience this has caused you. Thanks for your patience while we fix it. kind regards AnSo

Complete failure to open.

Was one of my most valuable apps until the latest update. Now all I get is the whirling circle of paralysis. What a disaster of an update. Please fix, or refund my subscription
