“I did not build OCA as a business. I am a neurodivergent mum, and I built it for myself first, because I needed it to get through my own days.”

OCA
The story behind the name

OCA is the word my ancestors
used for home.

In the Tupi-Guarani language of the indigenous peoples of Brazil, oca is the name for the collective home. A large structure built together, over one week, held by the whole community. Several families. No walls between them. No one carrying it alone.

I am Brazilian. I have indigenous roots. And I built this app because the oca is the thing modern motherhood has lost. Not just a house. A held place. A community that builds alongside you. A home that organises itself around the people inside it, not the other way around.

That is what OCA does. That is what it is named for. Welcome home.

Etienny Trindade, founder

You are not
disorganised.
Your brain is full.

There is a browser open in your head with 47 tabs. You are the calendar, the cook, the cleaner, the appointment booker, the permission slip signer, and the one who knows where everything is. You do all of this while managing a brain that processes the world more intensely than most people around you understand.

Every app ever built for you was designed for a neurotypical brain by someone who has never sat in a Facebook group at 11pm reading what you actually need.

OCA was built from exactly that listening.

🧠
The invisible operating systemYou hold the entire household in your head. Appointments, groceries, who needs what, what is running out, what is due. Nobody else sees it. Your body feels all of it.
😔
The isolationYou are doing this without a village. The neighbours who took the kids. The aunty who brought dinner. That village disappeared and nothing replaced it.
🔋
The depletionBy the time everyone is in bed you have nothing left. Not for yourself. Not for the things that matter to you. Not for the person you are building.
📱
The wrong toolsEvery app you have tried was built for a neurotypical brain. They ask too much. They overwhelm. They do not stick. Because they were not built for you.

Designed for her.
Built for everyone.

OCA was built with neurodivergent mums in mind, because they feel the load most sharply. But it is for every exhausted mother, and every family that wants to carry the home together: the partner who wants to help, the grandparents who want to stay close.

👩
For her
The mum
Whether you have a diagnosis or you just recognise yourself in the exhaustion. Your brain never stops. This app holds what it has been trying to hold.

His own simplified view, 3 sections only
One suggested task each day
Monthly question: what can I take off her list?

I am on my way, one tap, mum notified
Pharmacy items shared directly
Optional: meet other grandparents nearby

Built for the most sensitive nervous system.
Which is exactly why it works for every home.

The ramp cut into a kerb was built for wheelchairs. It turned out to help everyone, the pram, the suitcase, the tired legs at the end of the day. OCA is the same. It was designed for the neurodivergent mind, the one that feels every open loop and unfinished task most sharply. And when a home is calm enough for that mind, it is calm for everyone who lives in it. Whatever your household looks like, OCA was built to lift it.

💛
Two lives, one calendar
Couples, no children yet
Two careers, two sets of plans, and the quiet friction of who remembered what. OCA holds both your lives in one shared view, so the load is never silently one person's.
One shared calendar, both your colours
Whose turn for the shop, the dinner, the bills
Plan trips and big goals together
Hand anything over in one tap
👨‍👩‍👧‍👦
Many lives, one clear view
Big families
Several kids, several schedules, activities stacked on activities, and a brain that cannot hold it all at once. OCA lays every child on their own colour, together, or one at a time.
A calendar for each child
Shared lists that never double up
A week of meals planned in minutes
Everyone helps, nothing slips through
🌱
The extra, invisible load
Raising a neurodivergent child
Therapies, plans, appointments, and the routines that keep your child regulated, a weight only you seem to carry. OCA holds the routine and finally lets you share the load.
Appointment checklists that repeat themselves
Every therapist and OT in one place
Visual routines and regulation tools
Carry it together, not alone
🧒
The everyday juggle
Families with children
School notes, pickups, swimming, the party on Saturday, the thing still in the dryer. The ordinary load that never ends. OCA remembers it so your head does not have to.
School and activity calendars
Snap a school letter, it reads the date
Quick lists you both update live
A gentle win journal at day's end
🤍
Carrying it, or sharing across two homes
Solo & co-parenting
Doing it all alone, or coordinating across two houses without the friction. OCA can share only the children's calendar with the other parent, and nothing else of your life.
Share just the kids' calendar, privately
Everything in one place when it is all you
The Village, for the days you need people
Your home, your boundaries
🧠
Built around your brain
Neurodivergent adults & couples
Just the two of you, or a full house. OCA was built around the mind that feels everything. Speak it and it is saved. Low-demand days for when the tank is empty. No shame, ever.
Voice capture, no typing needed
Low demand day mode
Gentle prompts that never shame you
One calm place, not 47 open tabs

Everything your brain
has been trying to hold.

Now held for you.

🎙
Voice capture
You remember something at 2am. Tap, speak, saved. The gap between I need to remember this and I will put it somewhere later is where everything disappears. This closes that gap.
🛒
Universal shop list
Not just groceries. Pharmacy, kids clothing, home items, Pinterest pins, links. Everything you need to buy in one place with photos and notes so you never forget what you saw or what size it needs to be.
📷
Scan it. Bin it.
She photographs a paper bill. The app reads the amount and due date. She throws the paper in the bin. The bench is clear. That pile is not just mess. Every unresolved item costs your nervous system something.
🌿
Recharge protected
Your bath. Your walk. Your quiet cup of tea. Scheduled as protected time. Not optional extras. Not something you earn. Medicine. Because that is what they are.
🤝
Find your village
Match with women nearby by energy, not algorithm. The woman three streets away who is also carrying this. You walk past each other at the library and never connect. Until now.
Home guides
Seven step-by-step systems written by Etienny Trindade. Backed by 20 years of environmental wellbeing research. The calm corner. Toy rotation. The laundry system. All with the science behind them.
⚖️
Mental load, shared
A gentle gauge of how much is on you versus shared with your partner, and one tap to hand something over. The invisible work, finally visible, so you are not carrying it all alone.
📅
Layered family calendars
A calendar for you, your partner, each child, the nanny, your own to add. See the whole family at once or one person at a time, in a clean week view like a planner.
💼
A business space
Run your business from the same brain without the worlds colliding. Business to-dos and a content schedule, by voice or typing, kept separate from home so your nervous system can switch cleanly.
🍲
Meal planner
Save a meal once, reuse it any week, and send the ingredients straight to your shopping list. Decisions removed, not added.
🌙
Rituals and regulation
Build your morning and evening rituals, one step at a time. The Reset, box breathing, an outside-on-the-earth reset, grounding. Tools for the moments your body needs them.
📖
Win Journal
Three soft prompts each night. Your brain remembers the hard things. OCA remembers the good ones, with a gentle streak that never shames you.
🔧
Professionals and files
The plumber, the OT, the cleaner, saved with why you loved them and shared with your partner. Plus one place for your documents, plans and notes.
👫
Built for the whole household
Your partner gets the full app to truly share the load, minus your private tools. Add shift patterns to the calendar. Invite up to four people by link or QR.

Not a wellness app.
An evidence-based
nervous system tool.

Every colour, every feature, every word in OCA was chosen based on research. Twenty years of Etienny Trindade designing environments that regulate the nervous systems of the people inside them.

Every guide has three levels of depth. A warm sentence for the mum who is exhausted. A paragraph for the curious. A peer reviewed study for the woman who needs to understand the mechanism before she can trust the solution.

Colour and sensory science
Soft blues, muted greens, warm neutrals, and muted purples are proven to reduce cortisol and promote calm in brains with heightened sensory sensitivity. Every category colour in OCA was chosen from this research.
Sensory Processing and Environmental Colour, Journal of Environmental Psychology
Cognitive load and mental load
Research shows 72% of household cognitive labour falls to mothers. In 29 of 30 tasks, mothers carry more of the thinking. The invisible load is not a feeling. It is a documented measurable reality.
Cognitive Labour in Dual-Income Households, American Sociological Review
Interoception and burnout
The ability to notice your own body signals is one of the first things lost in burnout. The daily tank check-in is based on interoception research. Rebuilding that awareness changes everything.
Interoceptive Awareness in Burnout Recovery, Frontiers in Neuroscience
Visual clutter and stress
Unresolved visual items in the environment activate the brain's task management system continuously, creating background stress even when not consciously noticed. Clearing the bench is not housekeeping. It is nervous system care.

Neurodivergent mum who built this for herself first
When your home begins supporting your nervous system instead of stimulating it, calm stops being something you try to create. It becomes something your body naturally experiences.

Be one of the first
to walk home.

A small founding circle gets in first, while OCA is still being shaped around them. They help decide what gets built next, and their founding price is held for them for the first two years as the app grows. When the founding spots are full, they are full.

You were never meant
to do this alone.

Every generation before us had a village. The aunty who brought dinner. The neighbour who took the kids. That village quietly disappeared and nothing replaced it. OCA helps you find yours again, women nearby who understand what you are carrying, matched by how your days actually feel. Privately, gently, on your terms.

What is OCA, the app for a mum's mental load?+

OCA is the first home management app designed around the neurodivergent nervous system. Built by Etienny Trindade, an Environmental Wellbeing Designer with 20 years of experience, it combines task management, grocery lists, family coordination, bill scanning, a community village, and nervous system support in one calm app. Built for ADHD and autistic mums, and every overwhelmed mother carrying the invisible load.

Is OCA only for neurodivergent mums, or any overwhelmed mum?+

No. OCA was designed with neurodivergent brains at its centre, but it is for every overwhelmed mother. Research shows 72% of household cognitive load falls to mothers regardless of neurotype. If you are carrying everything in your head and have nothing left, OCA was built for you. You do not need a diagnosis to feel seen here.

How much does OCA cost, and is there a free way to start?+

Right now you can join the waiting list for free, and testing OCA is free while it is being built. Founding members get a special founding price that is held for their first two years as the app grows. There is nothing to pay to join the list today.

Does OCA work for the whole family, partner, grandparents and nanny?+

Yes. The partner gets his own simplified view with three clear sections. Grandparents get Grandparent Mode, a large-text experience they access from one link with no login needed. The whole family is thought of, not as an afterthought, but as a core part of how this app was designed.

How is OCA different from other family calendar and to-do apps?+

Every other home management app was built for a neurotypical brain. OCA was built by a neurodivergent mum with 20 years of environmental wellbeing expertise after months of listening to what overwhelmed mothers actually need. The science-backed colour palette, the nervous system recharge tracker, the pause button, the energy-based village matching, and the 7 home guides are features no other app offers. The expertise behind this cannot be replicated.

Is OCA available in Australia and other countries?+

Yes. OCA is built and priced in AUD. Created by Etienny Trindade, based in Adelaide, South Australia. Launching in Australia first and expanding internationally, including Brazil and Portuguese-speaking communities globally.
