LCt50 Calculator

By Pearson-Cole Software

This app is only available on the App Store for iOS devices.


Utility for determining three different lethal concentration and time (LCt50) calculations when using chlorobenzalmalononitrile (CS) non-lethal chemical agent inside a structure. The formulas are based on a government study using animals and soldiers to determine the amount of agent that will likely kill 50% of the people in a closed sealed space using the amount of agent and time as a factor.

The app's easy-to-use forms require the user to enter the length, height and width of a structure, along with how much agent was used. If you want to determine the amount of the agent you can safely use in a building, the app will tell you the LCt50 after one simple numeric entry by the user. You can also determine how much agent to use for any LCt50 you want to establish.

Every team leader responsible for the delivery of chemical agents can make use of this app.

What's New in Version 1.2

64-bit support. Price increase due to the agonizing process Apple puts developers through just to rebuild their apps with zero code change just to support newer devices/OS versions. Get it on Android for free since it doesn't cost $100/year and weeks of my life just to maintain this simple app there.
NOTE: Apple couldn't make the process of rebuilding the application "just work", and as a result, the tab buttons no longer have labels. I've spent far too many hours trying to figure out how to fix something that would never have been broken on any other company's watch in the history of software production, so it's just going to have to remain as is.
