Animal Age converts the ages of various animals against human lifespans. See life expectancies based on different breeds of animal. Calculates age against human age.
This is what happens when an app is written based on a web page script with not authoritative vetting / support for what it presents. I have failed college student papers for this... and even flunked a student out who didn't wise up.
The numbers generated for just dogs and cats would make docs in my location's vet clinic spit their coffee across the room, stare, and only then laugh. Even the life expectancies (which like humans are based heavily on immediately environment / climate) are off.
Calculations are way off. 10 human years = 1.5 cow years? Also, the math is totally linear which does not accurately reflect animal age in younger years. Looks nice though.
