The app gives producers access to temperature and humidity index readings.
It also allows them to calculate their animal's breathing rates.
The app provides a stopwatch feature which helps count the number of breaths for an animal over a short period.
"The producers can go in and detect which animals are more heat stressed in a particular setting and go to additional means to reduce the level of heat stress in those animals," Don Spiers, MU Animal Science Professor, says.
Researchers hope to develop a database that will allow them to make better predictions about how animals respond to heat stress.
