### 5/5 — User friendly

*2024-09-27*

The interface is designed keeping in mind the anaesthesiology practitioners and not a generic one. Backend tech team is very prompt to sort out your technical ignorance. Loads better than college logbooks. Give it a try before concluding.

### 1/5 — Wasted money

*2024-01-18*

Wasted my time and money typing everything and now unable to export the data to take printouts. Don’t download

### 1/5 — Bug with editing the procedure

*2023-06-07*

Total scam! Dont download.

### 5/5 — Gopinath

*2023-04-03*

Very good app. Easy and intuitive to use. Summary report within seconds is just too good.

### 3/5 — Won’t let me upgrade

*2023-02-17*

It’s a great logbook but I’ve got to 30 cases and it won’t let me upgrade to premium.

Nothing happens when I press the upgrade to premium option. 

Not sure if deleting and re-downloading will help but I don’t want to lose my log by doing that!

### 1/5 — In app purchase didn’t work.

*2022-08-30*

Was good to start but then paid for premium access as otherwise you can only log 30 cases, despite paying £24 and doing usual trouble shooting still wouldn’t allow me to log any more cases, contacted app and heard nothing, still waiting for refund. Wouldn’t recommend.

### 5/5 — Very good App for trainees

*2022-01-26*

Very useful application for keeping an upto date log. Very easy to use.

### 1/5 — A great app with a horrendous price tag

*2019-10-24*

I used this log app as an anaesthetic nurse, it’s fast and simple compared to some of the paid log apps, which suited me, and it was very intuitive to add and navigate cases. 

However after entering a number of cases, I was served a prompt that told me I had hit the maximum number of cases for the free version, and would need to pay $41.99 to add any new cases. A quick look around the App Store shows the most popular anaesthetic log app as $7.99, with more features (that I don’t need or want, but I’ll put up with them to save $34!). 42 dollars is just a crazy price!

### 4/5 — ICloud support

*2019-03-11*

Great app. Easy to log cases but crashes when attempting to use iCloud storage to import and export on iPhone.

### 5/5 — Worth it

*2018-09-19*

Used this app for two years then for technical reasons had to use another app. Had to switch to many others just to adhere to Log4AS quality but was never satisfied enough. I’m glad I’m back to using it now and I’ve noticed how much more convenient, thorough, bright and user friendly it is. Good work!
