iPhone
Your exact age in years, months and days — live — plus countdowns and reminders for every birthday that matters. Leap-year correct, private, on your iPhone.
How old am I — exactly? AgeYears answers to the day: years, months and days, plus a live count of every day you have been alive, for you and everyone you love. And it makes sure you never miss another birthday.
Most age apps get the hard dates wrong. AgeYears is built on exact calendar math: February 29 birthdays are observed on February 28 in non-leap years, month lengths are handled correctly, and a stored birth date can never shift by a day when you fly across time zones. The subtraction is right — every time.
WHAT YOU GET
• Open the app to "34 years, 2 months, 11 days" — with 12,491 days alive ticking live on screen
• "23 days until Mum turns 60" waiting at the top every time you open the app
• A reminder on the day and 3 days before it, so the card gets bought and the call gets made
• The weekday you were born, your zodiac sign and its element, all on one card
• Milestones you would never compute yourself: your 10,000th day alive, your 2,000th week, turning 40
• A date-to-date calculator for any two dates — the exact span in years, months, days and weeks
PERFECT FOR
• Anyone who has to pause at "how old are you?" — the exact answer is one glance away
• Family record-keepers tracking parents, kids and grandkids in one clean list
• Friends who refuse to be the one who forgot the birthday
• Paperwork that asks for chronological age in years, months and days — pediatric visits, therapy intake, school forms
WHY NOT JUST USE THE CALENDAR?
A calendar shows you dates; it will not tell you your mother turns 60 in 23 days, that you have been alive 12,491 days, or that your 10,000th day on Earth lands on a Saturday next spring. AgeYears does the arithmetic — correctly, leap years included — so you never have to.
PRIVATE BY DEFAULT
Everything stays on your iPhone. No account, no sign-up, no cloud, no tracking. Your family's birth dates are yours alone.
