Memory is not enough. Conversations scatter across phones, arrangements change at the last minute, expenses vanish into receipts, and six months later nobody remembers who said what — or on what day.
ospais brings all of that into one place: conversations, calls, custody, calendar and a diary. And the money too — shared expenses, invoices that arrive by email and read themselves, credits and debts. All dated, all yours.

How this came about
This didn't start out as a product. It started because I needed it.
When a separation goes badly, a problem nobody warns you about turns up: everything that matters is scattered. The messages on your phone, the calls on the operator's bill, the weekend handovers in each person's head, the children's expenses on receipts inside your wallet. When you have to explain anything at all — to a lawyer, to a judge, or just to the other person — there is nothing to get hold of.
I built this for myself, and I came to see that the useful part was not storing things: it was cross-referencing them. Knowing who the children were with at that hour puts a missed call in a different light. An expense tied to the start of the school term explains itself. A conversation exported with the date and the fingerprint of the original file stands as a serious record, not as a screenshot.
The obvious escapes us until we stop and look at it properly. If you are going through this, you probably recognise the problem better than any description I could write here.
Everything that matters is scattered.
The useful part was never storing things: it was cross-referencing them.
What it does
Conversations
Import your WhatsApp exports along with the attachments. Everything becomes searchable, next to the calls, with edited and deleted messages flagged, and the original file sealed.
Calls and SMS
Import the records from your operator (CSV). You see who called whom, when and for how long, next to everything else.
Responsibilities
Week on, week off, with the handover time. Changes and periods are recorded, and each day shows who the children were with.
Schedule and reminders
School and activity timetables, reminders, school holidays and public holidays. It alerts you on your phone in time to leave the house.
Expenses
It reads the QR code on receipts, imports the tax-office CSV and splits invoices that bundle different things together. You always know what is owed to you — and the claim comes out as a PDF, with the documents attached.
Invoices by email
Every family has an address of its own. You forward the invoice and it arrives with the attachment saved and the fields already read from the PDF — amount, tax number, date and invoice code.
Credits
The mortgage instalment is not all cost: part of it is principal, which is equity. From two bank balances, the app separates interest from principal — and charges only what is fair to charge.
Debts to companies
The school, the clinic, the lawyer. A running account line by line, with the invoice attached to the invoice’s line and the receipt to the payment’s. The balance is what is left to pay.
Diary and evidence
The day-to-day record, with photographs, audio, location and links to everything else. This is what you later hand over, organised.
The document that comes out of this
You pick the period and the sections, and out comes a document ordered by date — with the figures, the originals attached and each one’s digital fingerprint. That is what you hand over, not a folder of screenshots.
Screens from the app, with demonstration data.
Forward the invoice. Done.
Every family has an email address of its own. The clinic sends you the invoice, you tap forward — and it arrives here with the PDF saved and the fields already read: amount, tax number, date and invoice code.
You forward itFrom your phone or your computer, like any email.
It reads the documentThe receipt’s QR code, the PDF’s text, and OCR when it is a photo.
You confirmNothing enters the archive on its own: it waits for a tap from you.
The address is kept the way a password is kept — and can be swapped at any time if it gets around.
Half the instalment is not half the expense
A mortgage instalment has two very different parts. interest is a cost: money that goes out and does not come back. principal is debt that ceases to exist — and if the house belongs to both, that equity is the other parent’s too.
After nineteen years, in an instalment of €452.80, €448.20 is principal and €4.61 is interest. Asking for half the instalment would be asking €226 a month for something that is already hers.
Here it asks for €2.30.
The split comes from two of your bank balances, subtracted one from the other. No rates, no amortisation tables, nothing estimated — and until there are two balances it charges nothing rather than charging too much.
Giving access without opening everything
You can invite whoever you need: another family member, a mediator, your lawyer. Each person sees only what you give them: one section, a set of conversations, or limited access — only certain numbers, within a date range, and even with a maximum call length.

★★★★★
Uma aplicação verdadeiramente completa e indispensável!
OsPais é muito mais do que uma aplicação de controlo parental: reúne gestão financeira familiar e pessoal, agenda, alarmes, lembretes e resumos, tornando-se uma ferramenta essencial para o dia a dia. Quando começamos, não conseguimos mais viver sem registar!
Para pais separados ou divorciados, é especialmente útil: permite registar e solicitar despesas à outra parte diretamente pela app ou por email, com os respetivos comprovativos anexados — uma funcionalidade extremamente prática e inovadora.
E não fica por aqui: permite exportar conversas, adicionar fotografias, importar diretamente do e-Fatura, gravar áudios e registar acontecimentos através de PDF, fotografia ou código QR.
O melhor de tudo é que fica tudo organizado e registado, criando um histórico completo e facilmente consultável, que pode ser muito importante como suporte documental e até jurídico quando necessário.
Uma aplicação muito bem pensada, completa, prática e realmente útil, que simplifica a gestão familiar e pessoal e ajuda a ter tudo sob controlo num único lugar. Recomendo vivamente!

★★★★★
Muito útil para quem tem guarda partilhada.
Ajuda bastante a organizar despesas, pagamentos e tudo o que fica combinado entre os pais.
As notificações são uma grande ajuda para não esquecer datas ou obrigações importantes.
É simples de usar e evita muitas mensagens e confusões desnecessárias.
Ter tudo registado num só sítio dá bastante jeito no dia a dia.
Até agora, estou muito satisfeito com a aplicação.

Only people with an account here can leave a rating, one per account, and we ask inside the app. We publish them all — we do not pick the good ones. We only take one down if it contains insults or someone else's personal details, and the reason is recorded.
Before you decide
This app records what you already have: your conversations, your call logs, your expenses. It does not access anyone's phone, it does not track other people and it does not collect anything in secret.
Nor do we tell you that this "holds up in court": what holds up and what doesn't is for the court to decide. What we do is keep things dated, with the original file intact and with a log of everything that was done — which is what makes a record a serious one.
