Two panes on iPhone Duo.
Unfold iPhone Duo and Contamos splits right at the fold, each pane on its own half. Fold it and the same screens fit the cover. On any other iPhone, it all works on one screen.
Better together.
Money is easier when you look at it together. Invite your partner or family and everyone works from the same numbers.
Invite your partner
Share your household's invite code and your partner joins with their own login.
Mine, yours, together
Home, Activity, Budget, Goals and more can show just you, just your partner, or the whole household.
Side by side
See who spent what at a glance, without turning money into a scoreboard.
Accounts and net worth
Checking, savings, cards, loans and retirement accounts, with your household's net worth over time.
Alerts
A heads-up when a card nears its limit, a budget runs low, or a bill is about to renew.
Cards
Balances, limits and due dates for every card, plus payment reminders.
We never see your bank password
You sign in to your bank through Plaid. Contamos gets read-only data, never your login.
Locked to your household
Database rules check every read and write, so only members of your household can reach its data.
Encrypted in transit and at rest
TLS on every connection, and encryption at rest for our database and file storage.
No ads, no trackers
No advertising or analytics SDKs in the app, no tracking cookies here, and we never sell your data.
Questions, answered.
Is Contamos a financial advisor?
No. Contamos is a budgeting and tracking tool. It isn't a bank, an investment adviser, a broker or a tax professional, and nothing in the app is financial, investment, tax or legal advice. For decisions like those, talk to a licensed professional.
How does bank linking work?
We use Plaid, which connects to thousands of U.S. banks. You sign in to your bank inside Plaid's secure screen; Contamos only receives account names, balances and transactions. You can disconnect a bank from Settings at any time.
What can my partner see?
Everyone in a household sees the household's accounts, transactions, budgets, bills and goals. That's how sharing works, so only invite people you trust and only link accounts you're happy to share.
What does it cost?
Contamos will be free during its public beta on TestFlight, which opens soon. If we introduce paid plans, you'll see the price in the app before you pay, billing goes through your Apple ID, and you can cancel any time in your iPhone's settings.
Do I need an iPhone Duo?
No. Contamos runs on iPhone. On iPhone Duo it uses both halves of the inner screen, and the cover screen when folded.
How do I delete my data?
You can disconnect banks and delete accounts or transactions in the app at any time. To delete your Contamos account entirely, see Delete your account.
