Two homes, one childhood
The app that organizes your children's time in shared custody: a calendar that mom, dad and every caregiver see the same way, day swaps that only count when both approve, and a history that cannot be edited or deleted.
Free for both parents · no credit card · also in the browser, iPhone included · app in English and Portuguese
The idea
The child goes back and forth. What cannot go back and forth is the agreement: whose day each day is, when it changes, and who approved the change. That is what Entrelares keeps — identical for both homes.
What happens today
Because an agreement buried in a conversation turns into an argument: the message gets lost, each of you remembers it differently, and the child is caught in the middle. The app exists to take the schedule out of "nobody told me".
Example conversation
How it works
Each step with a real screen of the app — no staged demo.
Each of you signs in with your own account. You can also include grandparents and other caregivers who take part in the routine.
Set whose day each day is, following your own agreement — alternating weeks, fortnights or a cycle of your own. Holidays and special dates you adjust on the day itself, or on several days at once.
The other parent approves or declines, and until they answer the day stays as it was. Everything is recorded, with date and time.
A sentence cannot prove that a record is unchangeable. These are two real screens of the app following the same request — the swap for 31 Aug — from the approval card to the line nobody can take back.
Features
Every detail exists to answer one question quickly and prevent one argument. Real screens from the app.
Open it and see straight away whose day it is — today, tomorrow and across the whole month. A different color for each caregiver, and the next handoff always in sight.
Set who is responsible, the time the child changes homes and a note for each day — the day note is free.
A swap becomes a request the other parent approves or declines. No surprises, no "nobody told me".
Every swap, approval and change is recorded with date and time, in a history that cannot be edited or deleted. If what you agreed ever turns into an argument, it's there — in black and white.
Grandparents, stepparents and other caregivers can join the family and take days, under the same approval rules — each with their own color.
School, health, medicines and activities for each child show up on the calendar day, with the time and who wrote them — and reminders for whoever you choose.
Each expense split the way you agreed, with each person’s balance and the fewest payments to settle up. A payment counts only once the person receiving it confirms.
Family-only, permanent, with read receipts on every message. What was said stays available, and can go into the PDF report.
School, health, medicines and activities for each child, with routines that repeat and reminders for whoever you choose.
Each expense split equally, by amount, by percentage or by shares, with each person's balance. A payment counts only once the person receiving it confirms — the app never moves money.
One conversation for the whole family that nobody can edit or delete, showing who has read each message.
For people who follow without deciding — a grandparent, a nanny: they see the calendar, the agenda and the reports and get the informative notifications. They change nothing.
The period's report carries a QR code: whoever receives it checks that the file was not altered, and the document is never kept on our servers.
For every family
Each person joins with the role they play in the child's life — 21 built-in ones, or your own on Premium — and whoever only follows along joins as a viewer.
"We both needed to know clearly whose day each day was. I tried a spreadsheet, I tried an ordinary calendar. So I built something of my own, something simple, and it grew until it became a true partner in the time I share with my son."Irineu — founder of Entrelares, and a father in shared custody
I was married for 20 years, and that marriage gave me the most precious thing in my life: my son. When his mother and I realized we would not stay together, we chose to separate with everyone's good in mind — his above all.
Suddenly everything was new: the house, the routine, the habits. But one thing didn't change — wanting to be present in my son's life. Amid the natural friction of a recent separation, what we needed most was exactly what seemed hardest: giving a small child stability and predictability, while fitting everything around his mother's demanding work schedule.
We both needed to know clearly whose day each day was. I tried a spreadsheet — it helped at first, but it soon got complicated and was never at hand when it mattered. I tried an ordinary calendar — too much work to keep up. So I built something of my own, something simple, and it grew until it became a true partner in the time I share with my son.
Talking with other mothers and fathers who had been through a separation, I found the same gap. That's why I decided to open the tool to other families — to take that friction out of the way at such a delicate moment, one you get through with care, love and, above all, respect between everyone involved.
