Worldwide, per day, and installs to date. The band is open; the exact number is free with an account.
How this is calculated
Apple publishes no download counts. App Store downloads come from chart positions and daily rating growth per country, calibrated on Google Play install counts; lifetime installs from ratings worldwide × installs per rating. Confidence is the chance the real number is within half to double ours.

Review momentum
20/100
faster than 0% of Medical apps
Review momentum (0-100) blends how fast the app collects ratings compared with other apps in its category (60%), whether that pace is speeding up (25%) and what recent raters give it (15%; recent stars well below lifetime pull it down). Ratings counts are read daily. A jump usually means a launch, a feature, ads or a new review prompt.
About Chemical Hazards Pocket Guide
The industrial hygiene information found in this Pocket Guide assists users to recognize and control occupational chemical hazards. Content is sourced from the National Institute for Occupational Safety and Health (NIOSH®) Publication No. 2010-168c.
The information provided is a concise source of general industrial hygiene information for workers, employers, and occupational health professionals.
As a fully tested and recommended application by Laboratory Safety personnel, you will find it easy to use with full use of the iPhone's native look and feel throughout.
Readable References:
The iPhone is very capable of reading many PDFs and HTML pages available on the internet, but we have found that quite often there is a fair bit of panning, pinching and zooming required to read files intended for PC Desktops. You'll find the ancillary references in this Pocket Guide reformatted to an easy readable format set to the iPhone's display.
Emergency Response Guidebook (ERG):
The ERG from the Department of Transportation is primarily a guide to aid first responders to quickly identify and protect themselves and the general public during an incident's initial response phase. The appropriate guide is presented for each chemical in a readable form on the iPhone for your education and quick reference.
Clean, Simple Design:
We love the iPhone too, so we made sure this Pocket Guide feels like it came with your device and always remains responsive to each touch request. You'll notice that each portion of the Pocket Guide for the iPhone is not just a set of canned HTML or PDF files!
Offline Access:
No internet connection required!
Quickly find chemicals:
Search for any chemical quickly and easily using any portion of the name or CAS/RTECs number.
Browse the list of chemicals by synonym, common or registered trade name using the available alphabetic index. Any viewed chemical will appear in the History tab to allow for quick lookup during the next use.
Features:
* Fully indexed and searchable chemical list by name, CAS# or RTECS#
* Full text of all referenced DOT Emergency Response Guides
* Viewable International Chemical Safety Cards
* All NIOSH appendices
* Saved History of previously view Chemicals
* Native iPhone look & feel throughout
* No Internet connection required
