THE SCIENCE BEHIND THE APP
Traditional dog age calculations are oversimplified. Modern research shows that dogs age rapidly in their early years, then slow down as they mature. Our formula uses natural logarithms to accurately model this non-linear aging process.
The calculation: human_age = 16 × ln(dog_age) + 31
This formula accounts for the epigenetic changes in dogs' DNA as they age, providing unprecedented accuracy in age conversion.
