Add an expense, Eider splits it, everyone settles up.
Add the expense
Amount, what it was for, done. Eider remembers your usual split, so most expenses take one tap.
The balance keeps itself
Everything nets down to one number: who owes whom, right now. No spreadsheet, no math at dinner.
Settle up for real
One payment clears the period. Eider opens the app you already use and records that you're square.
From bought to settled.
- Add
Two taps and an amount.
The numpad opens on the amount, the category is guessed, and your usual split is already applied.
- Split
Eider divides it up.
Even, by percent, or exact amounts, with a row per person and the totals reconciled as you type.
- Balance
One number, not a pile of IOUs.
Every expense nets into a single line: who owes whom, right now.
- Settle
Then the period closes.
One payment clears the period, in whichever app you already use. Eider records it and the nest goes quiet.

Eider is for people who keep their money separate.
Share one account and there is nothing to split. Keep them separate and Eider is the shared record of every expense you split.
Trips and friend groups
Someone fronts the house, someone else buys dinner. Everyone's square by the flight home.
Works the same at two people or eightRoommates
Four people and one internet bill. Everyone sees the same numbers, so nobody has to chase anyone.
Add as many members as you likeCouples with separate accounts
Rent, groceries, the vet. Set the split once and stop re-deciding it every month.
One standing split, applied for you
Eider keeps your balance up to date as you go.
- Evenly, by percent, or exact amounts
Set it per expense, or once as the nest's standing rule.
- A split you set once
The usual rule is applied for you. Update it when the arrangement changes.
- Repeating expenses
Rent, utilities, subscriptions. Fixed or variable, added on schedule.
- Full history and filters
Every expense stays, and stays findable. No archive tier.
- Netted to the fewest payments
Eight people settle in seven payments at most, not 28 IOUs.
- Fine on your own
Start a nest on your own. Invite the others whenever you're ready.
Settle up in the payment app you already use.
Pick where the payment happens. Eider hands off, then records that the balance is clear.

Eider never holds or transfers money. It keeps the record of your expenses, then your bank and your payment app do the rest.
- Is it actually free?
- Yes. Everything on this list is free, with no caps and no ads. Plus adds extras on top. It does not unlock any of this.
- Does Eider move money?
- No. Eider records the settlement and opens the payment app you chose.
- Does it work for more than two people?
- Yes. A nest works the same whether you share expenses with one person or eight.
- What if the other person never joins?
- A nest works solo. Your balance and history are yours either way.
So, what's an eider?
A sea duck whose nest down is the lightest, warmest insulation there is. It fills the world's most expensive comforters. People have gathered it by hand for centuries, and the ducks keep the nest either way.
That is where the name comes from, and it is why a shared set of expenses in Eider is a nest. You and whoever you share money with are lining it together, one expense at a time.
- 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.
Plus takes on the parts you'd rather not do.
Everything above stays free - none of it moves behind this. Plus is the tedious half: the typing in, the working out, the remembering.
Snap the receipt
Take a picture of it and watch it become an expense. All the information is captured automatically and all you need to do is review it and add the expense.
Split it line by line
Split the bottle of wine between the people who actually drank it. Make sure your roommate pays for the decorative item from Target you didn't want.
A bird's eye view of your money
Beautifully designed charts and spending patterns. Take a deeper look into how your nest spends each period.
Every member of every nest you create gets Plus benefits with an annual subscription. No date or price to announce yet. The free plan will never be capped. Plus simply adds useful features on top.
For a trip, a house, or two people who keep their money separate.
