About Mi Primer Diario: una vida
My First Diary is your son or daughter's diary, written by their parent.
Each day, the app asks you a question about them. You answer in a minute, with whatever words come to mind. There's no need to think about what to write or wait for the right moment: the question is already there when you open the app. As the months go by, these answers are automatically organized into a book with your photos, which you can download as a PDF and print.
WHY A DIARY AND NOT MORE PHOTOS?
You have thousands of photos of them, and none of them capture what they smelled like, what you were thinking that day, or why you didn't sleep. What their laugh sounded like at eight months old. The strange word they used to say. The last time they asked to be held without you knowing it was the last. You still know it today; in five years, you won't. It's not a bad memory: it's just that no one can keep track of so much. That's why you write it down as it happens.
HOW IT WORKS
1. Choose the stage you're in and create your child's journal.
2. Answer one question each day, and another one each week. Skip any you don't want to answer—it's perfectly fine; they'll still be there tomorrow.
3. Add your photos to each memory.
4. When you're ready, download the book in PDF format, already formatted and ready to print.
FOUR DIARIES, ONE LIFETIME
• Baby Journal — from pregnancy to the first year. The wait, the day they arrived, and their firsts. 50 memories.
• My First Years — from 1 to 4 years old. First sentences, first friend, first day away from home. 38 memories.
• My Childhood — from 4 to 10 years old. School, friendships, imagination, fears, and ordinary days. 33 memories.
• • My Teen Diary — Ages 10 to 18. High school, the people they choose, what they argue about, and what they'll be grateful for one day. 29 entries.
In total, more than 470 questions spread across 150 entries, designed for their current age. You start where you are today: there are no gaps to fill in or anything to recover.
WRITTEN TOGETHER
You can invite the other person who's going through this with you. You both write in the same journals, and everything ends up in a single book. The app uses the plural form, and there are questions for each of you.
And if you're raising a child alone, it's designed for that too: you choose what your family is like, and the journal reflects that, without assuming a "we" that doesn't exist.
A GIFT THAT NEVER WEARS OUT
You can give an entire journal as a gift. It comes with a card containing a code, they write in it for years, and it eventually becomes a book. For a baby shower, a birth, a christening, grandparents, or aunts and uncles who don't know what to buy.
YOURS AND NO ONE ELSE'S
There's no advertising. No wall, no followers, no public profiles: no one outside can see what you write. We don't share your data with third parties. You can download everything you've written and all your photos whenever you want, and delete your account from the app itself.
WHAT IT DOESN'T DO
It doesn't print or ship anything to your home: the book is delivered as a formatted PDF so you can print it wherever you like. It's not a social network. And it's not a pregnancy journal or a record of feedings, diapers, and naps: this is for what you write about, not what you measure.
THE PRICE
A one-time payment per journal and per child. It's not a subscription and it doesn't renew. You can create an account and see what each journal includes before unlocking anything.
You need an account to write, and your entries are saved in the cloud so they won't be lost if you switch phones.
