## Most critical reviews (5 lowest-rated)

### 1/5 — Does nothing

*2019-09-24*

App opens and brings up the menu, but despite tapping and swiping and any other touch maneuver I cannot do anything - the app just stays on the menu. Seems like there are some bugs that need fixing? Will check back and if I’m able to use will update my review.

### 1/5 — Does not function

*2017-10-18*

Downloaded this to do opioid dose conversions.  Cannot enter any numbers or get a cursor to appear.  Just read only interface with no conversion capability.

### 2/5 — Update needed

*2021-06-21*

Please update this app

### 4/5 — Great app but needs updating

*2021-06-10*

I use this daily at work but it needs an update to work with the new iOS.
Please add a buprenorphine and tapentadol calculator.  Would be helpful to update methadone to be in sync with the CDC guidelines (like a siding scale).

### 5/5 — Superb Medical App - Fast & Accurate

*2016-02-28*

I'm a practicing medical physician.  This is one of my favorite medical apps.  It allows one to easily convert various forms of opioids in a manner that I have found to be dependable, reliable, and safe. It seems to use an excellent algorithm for conversion.  The best thing about the conversion within the app is that it uses a slider that one simply moves with a finger, rather than entering numbers and adding a different drug to compare.  It's so efficient.  Very thankful to the app maker for this app.  I've used it for at least 3 years and was shocked to see that no one had ever reviewed the app.  It's worth adding to the list of "must own" medical apps for the iPhone or iPad.
