Estimated revenue
A model estimate with a likely range, not a reported figure.
No estimate. Apps outside the grossing charts, and some countries, have no reliable rank-to-revenue curve, so we show nothing rather than a guess.
How this estimate is made
Rank: we take the app's best Top Grossing rank on the latest chart day. Category ranks are converted into an equivalent overall rank, because a #10 in Finance earns far less than a #10 overall.
Curve: that equivalent rank is read off a rank-to-revenue curve anchored on public company revenue and market-data reports for the US iPhone App Store.
Country: the curve is scaled per country (Japan is roughly a third of the US, Türkiye under 1%). Where we have no scale, such as China, there is no estimate.
Range: the likely range widens with country, category and chart depth. It is a plausible span, not a statistical confidence interval.
Not included: ads, payments outside the App Store, and any difference between gross sales and what the developer keeps. Low confidence means indirect data; medium means several independent sources agree.

About this app
Text from the App Store listing.
Your best quick reference for hazardous materials. Includes: NIOSH, CFR/HMT, NFPA, GHS, CAMEO information.
This app serves as a quick reference and educational tool for employees that are involved with the regular handling and storage or incident response of Hazardous Materials.
Materials from the Hazardous Material Table (HMT) and Emergency Response Guidebook (ERG) are listed in easy to review form with advanced search, sort, and filter capabilities. Pertinent information from the HMT, ERG, NIOSH and other sources are listed with the proper placard and hazard class for each material.
The Hazardous Materials Table (HMT) 49 CFR §172.101 is a list of hazardous materials by proper shipping name that governs the transportation, marking and labeling by all modes: air, water, rail, and highway. Understanding and knowing how to use information in the HMT is the first step toward compliance.
The Emergency Response Guidebook (ERG) is primarily a guide to aid first responders in quickly identifying the specific or generic hazards of the material(s) involved in the incident, and protecting themselves and the general public during the initial response phase of the incident. The ERG is updated and released every 4 years by the D.O.T.
