### 2/5 — Very difficult data

*2025-05-19*

Go to www.pharmahub.info which makes the OB easier to research

### 2/5 — Carry a magnifying glass

*2023-10-12*

Appears to have similar functionality as the browser version, but it is NOT kind to your eyes.  Even with my reading glasses I cannot use it without a magnifying glass, and like a lot of dumb web dev contractors lately they go all-in on "low contrast" grayscale instead of dark gray or black.  I'll probably remove this app.

### 1/5 — No AB rating information

*2023-10-06*

The only reason I downloaded this app was to look up AB rating of different manufacturers. It was pretty much useless
