About this app

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.
- Full history and search - find any expense, any time.
- Works the same whether it is just the two of you or everyone on the trip.

FREE, AND ACTUALLY FREE
No ads, ever. No caps on the people or expenses you track. No trial that expires, no core feature held hostage. The essentials are free, and stay free.

Made for people who keep separate finances and just want the numbers to add up.
Split expenses on trips or at home. Settle up simply. Free, no ads, no limits.
