First password
Your everyday ledger
Dinners with friends, gifts for family, coffee for coworkers. Face ID or your fingerprint opens it too.
Who You Spend On
How much have Ispent on them?
A private ledger that adds up what you spend on each person. Dates and dinners, friends, family, gifts — only you can see it.
Coming soon to the App Store and Google Play
No servers, no sign-in, no ads. Your entries stay on your phone.
One app, two passwords
Each password opens its own ledger
Your first password opens an everyday ledger. An optional second password opens a separate one. You decide who goes where.
Second password (optional)
The one only you know about
Skip it and the app works exactly the same. Create it and it opens only when you type it in — and it leaves no trace in the first ledger.
- Totals and reports stay separate. Moving people is only available inside the second ledger.
- The second ledger is encrypted and locks the moment you leave the app.
- Forget the second password and you open it with the recovery code you got when you made it. We can’t recover it for you.
Quick to log, easy to read
Three-second entries
Tap the amount, pick a person and a category, done. The date defaults to today. Shared costs split evenly, or you can adjust each person’s share.
Totals by person
Switch between this year, this month and all time to see who you spent on, one line each.
Reports
Top people, share by relationship, month by month. Just the numbers — no scores, no judgments.
Date reminders
Anniversaries and birthdays, on the day or 1, 3 or 7 days before at 10 a.m. Lock-screen alerts never show names or amounts.
What you got back
Gifts go both ways. Turn it on in Settings to log what you received, too.
Moves with your phone
iCloud and Google device backups bring everything to your new phone. Use a backup file between iPhone and Android.
Your year, in one letter
Your summary card never shows names; choose a year, all time or a date range. Just the period, the total, what you spent most on and the split by relationship — shared as an image.
