Cairn
Your money. Your data.
A private personal finance app for iPhone, iPad, and Mac. No Cairn account, backend, or tracking.
Free app; separate bank connection
Cairn has no subscription or service fee. Automatic bank sync requires your own SimpleFIN Bridge account, a separate paid service billed by SimpleFIN—not Cairn.
Thank you to SimpleFIN for the Bridge service and SimpleFIN protocol that make direct, read-only bank connections possible. SimpleFIN is independent; its pricing, institution coverage, and terms are its own.
Privacy
Cairn processes data on your device. It communicates directly with the SimpleFIN server you choose and, only if you enable it, your private iCloud database. The Cairn developer does not receive your financial data.
