Why Eider?
An eider is a sea duck that lines its nest with down.
The name gave us a word for the shared space where you keep expenses: a nest.
- Money is a tense subject
- Splitting it should not be. Eider is built to feel soft, not sharp.
- Down, not feathers
- The soft under-layer, not the outer quills. Different material entirely.
- Gathered, not taken
- In Iceland it is collected by hand after the ducklings have gone.
Receipt tools and spending insights are planned for Plus.
The shared record, standing splits, repeating expenses, and settling up will stay free.
Scan a receipt
Use a photo to fill in receipt details, then review them before adding the expense.
Split by item
Assign individual receipt items to the people sharing them, instead of applying one division to the whole bill.
Review your spending
See your spending patterns over time, with insights available to the Plus subscriber.
An annual Plus membership will also cover receipt scanning and split by item for everyone in your nests. The receipt library, spending insights, bank sync, and early access will stay with the subscriber. What's free today stays free.
