Nona
Enjoy the trip. Let Nona do the math.
Nona records trip expenses and works out the settlement. Expenses stay on the device; only trips you create an invite link for are synced, encrypted.
How it works
- 1
Create a trip
Set a name, dates and base currency, then add the names of the people travelling. No account needed.
- 2
Log expenses
Pick the amount and currency, who paid and who shares. Split equally, by shares, by percentage or by exact amounts; each person's part is previewed as you type, and any leftover unit shows who took it.
- 3
Check balances
The Balances screen shows what each person is owed or owes, with a drill-down to the expenses behind it. The total is always zero.
- 4
Settle up
The Settlement screen proposes the plan with the fewest transfers. Tick each transfer as it's made; undo if you slip.
- 5
Record together
Create an invite link from the trip's Share screen. Any phone that opens it records into the same trip. Revoke the link to stop further joins.
What's inside
Rate provenance
Every converted amount shows the rate, source and time it used. A fixed per-trip rate applies retroactively.
Export
A paste-ready text summary and a CSV with a column per member.
Duplicate warning
The same payer, currency and amount within 60 minutes shows a banner — nothing is deleted for you.
Works with Packly
Pass city, dates and companions to or from Packly. Amounts never leave the app.
Frequently asked
The exchange rate isn't today's.
Rates are fetched once a day; offline, the app uses a built-in snapshot and says so on screen. You can also pin a fixed rate in trip settings.
I lost the invite link.
Open the trip's Share screen to see it again. The link contains the key, so don't post it publicly; if in doubt, revoke it and create a new one.
Where are trips I never shared?
Only on this device. If you lose the phone they are gone, so create an invite link once or export a CSV for trips you want to keep.
I can't delete a member.
Members tied to expenses can't be removed. Edit the expenses they paid or share first.
A calculation looks wrong.
Email us which trip it was. The rules follow a published spec and both platforms replay the same test vectors.
