Coamy+ grows: statistics, budgets, projects, currencies, receipts and export. Yearly plan at half price for the first year.
Coamy is the app for daily life as a couple: your shared expenses, your shared calendar and your lists, on both your phones, synced in real time. It’s built for exactly two people: every screen knows who the other person is, and calls them by name.
WHO OWES WHAT, AT A GLANCE
“Tom owes you $42.50”: Coamy does the math, you just read it.
• Add an expense in seconds, standing at the checkout: the amount, a label, a category, done.
• Paid by, and “For whom?”: shared, for one of you, or another split (60 / 40…).
• Recurring expenses, like rent or subscriptions, come back on their own every month.
• The monthly report: the amount to settle, “Copy the amount”, “Transfer done”, and the month is settled. Or carry it over to next month.
• Paid someone back mid-month? Note it, and the balance follows.
• No signal? The expense waits and goes out as soon as you’re back online.
ONE CALENDAR FOR THE TWO OF YOU
• The month with titles written right in the days, the week, the day.
• Each event is for you, for the other one, or for both of you, in its own color.
• A reminder at the right time, and straight from the notification: “Done”, “In an hour”, “Tomorrow”.
• Mark an appointment done, or postpone it.
• Repeats (every week, the 1st Monday of the month…), a place with address suggestions, notes.
LISTS YOU CHECK OFF TOGETHER
• “To do”, groceries, and as many lists as you need.
• One of you checks things off at the store while the other adds from home: everything updates live.
• Each item can be for one of you, or for both.
THE LITTLE THINGS, THOUGHT THROUGH
• “Keep to myself”: an event or a list item only you can see.
• A notification when the other adds an expense, or when a task lands on you.
• One currency per household; dates, times and the first day of the week follow your region.
• In English, French, German, Spanish, Italian, Dutch and Portuguese (Brazil and Portugal).
COAMY+, A LITTLE EXTRA COMFORT
One subscription covers your household: both of you, whatever your phones.
• Widgets: the balance, your list and your calendar on the Home Screen
• The Overview widget: the balance, upcoming events and a list in one place
• Twelve-month statistics and budgets by category
• Shared projects and savings funds
• Expenses in another currency, and receipt photos
• CSV export, monthly PDF statement and your year in review
• Up to eight pinned shortcuts, logged with Siri or Control Center
• A color for each of you, app icons and tint
• Several reminders for one event
• Past years and search in your history
• Your household’s places, suggested as you type

Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
Duo is now Coamy: a new name and a new logo, so the app is easier to find. Nothing else changes: your household, expenses, calendar and lists are all here, and Duo+ is now called Coamy+.
