Age Is Just A Number

How old are you on Mercury? How many animal lifetimes have you lived? Age Is Just A Number turns a birth date into playful comparisons that put time in perspective. Explore your age across the solar system, compare animal lifetimes, and discover unusual ways to count the years. Additional sections explore number bases, time units, body estimates, zodiac signs, insects, arachnids, fantasy creatures, historical eras and technology. Save profiles, compare results, copy an age snapshot, or share individual cards. Your saved profiles and settings are stored on your device. The free version includes Planets and Animals, one saved profile, and banner ads. Choose to complete an ad to unlock all comparison screens for 10 minutes for your selected age. Changing the birth date or selected profile ends the temporary unlock, and the timer continues while the app is closed. The optional lifetime Pro upgrade keeps every section unlocked permanently, adds unlimited profiles and removes ads. Designed for adults aged 18 and older. All comparisons are for entertainment. Body and lifespan estimates are approximate and are not medical advice.
