Income and expenses,
each on its own side
Your money. Your rules. Personal and shared in one place, with clear books and no spreadsheets.
Income and expenses
Log each movement with a category and date. Your month balance, always at hand.
Recurring items and reminders
Rent, subscriptions, salary: they're only logged once you confirm, with a bell and email reminder before the date.
One-to-one links
Link your account with one other person. What you share is visible between you; personal stuff is not.
Actually private
The other person only sees the movements you marked as shared. Nothing else.
Multi-currency
Log in dollars or another currency at that moment's rate. Everything adds up in your primary currency.
5 languages
Spanish, English, Portuguese, French and Italian. Everyone picks their own.
Books that close
Settle what you owe with a history log. Export everything to Excel whenever you want.
How it works
Someone already on BlackLab sends you a link by email or WhatsApp. No invite, no entry.
Pick your name, a @username and your primary currency. Verify your email and you're in.
Income and expenses, in any currency. Mark which ones you share and with whom.
BlackLab works out who owes whom. When you settle, it's on the record.
BlackLab is still a closed project: you can only join with an invitation from someone already inside.
