DogDays Premium

Behind the calculation logic in DogDays lies the experience of all the old ways of calculate as well as consideration of the estimated lifespan of each dog breed, compared to the average lifespan of humans! As well as the fact that all dogs, regardless of breed, reach human puberty in their first year of life. You will find that the estimates feel very reasonable. App languages are English (US and UK), Swedish, French, Spanish, Italian, Deutsch and Ukrainisch.
This is the ad-free paid version that also can save multiple dogs.
