Eider - Split Expenses

Eider is the free, easy way to split shared expenses whether on a trip or at home, then settle up simply.

No ads. No paywalls on the essentials. No limit on the people or expenses you track. Just a well-made ledger that does the math so nobody has to keep a mental tally.

HOW IT WORKS

• Start a nest for your trip, your household, or whatever you share.
• Add an expense in seconds. Eider remembers your usual split.
• See a running balance of who owes whom, simplified down to the fewest payments.
• Settle up through the app you already use: Venmo, Cash App, PayPal, Zelle, or Apple Cash. Eider records it, and it never touches your money.

BUILT FOR REAL LIFE

• Made for trips: throw every flight, cab, cabin, and dinner into one place and walk away square.
• Just as good at home: rent, groceries, utilities, and the everyday back-and-forth.
• Split any way: evenly, by percentage, or exact amounts.
• Set a standing split once and forget it.
• Recurring expenses for rent, utilities, subscriptions, and anything else.

FREE, AND NOT A TRIAL Everything above is free. No ads, and no cap on the people or the expenses you track.

EIDER PLUS - $8.99 a month, or $89.99 a year

• Scan a receipt and let Eider read the merchant, date, and total off it.
• Split one receipt line by line instead of evenly.
• A searchable library of every receipt your nest has captured.
• Spending patterns, period reports, and a monthly digest of where the money went.
• Connect a bank account and bring transactions in automatically.

Plus is a personal membership rather than a per-nest upgrade. An annual membership also shares receipt scanning and line-item splitting with everyone in the nests you create.
