Overview of a Tokyo trip: my spending, balances and who owes whom

A dozen expenses,
four transfers.

The hard part of coming home from a trip isn’t the photos, it’s the money: who paid for the hotel, who covered dinner, how the yen converts.

Split Robot converts every record into one currency, works out what each person is owed or owes, and simplifies it into the fewest transfers.

The hotel split by nights, Don Quijote paid separately, the yakiniku paid from the shared fund — all of it counted.
Record

Faster than sending a text.

Type sums on the calculator keypad, pick a name you used before, and the category is filled in from your past records.

Add a record

Record in the local currency; it converts for you.

Paid ¥1,480 in Japan? Choose JPY and enter the amount. It converts with your last rate or the latest one.

  • Type “Ichiran Ramen” and the category becomes “Food”
  • Scan Taiwan e-invoice QR codes for the amount, shop and items
  • Read the amount and date from a receipt photo, on your phone
Add record: ¥1,480 Ichiran Ramen, converted ≈ $10.06
Add without opening the app

Say it to Siri and it’s recorded.

“Add an expense in Split Robot” — say the amount and name, no app to open. Put it in Control Center, on the Action button, or run it after paying with Apple Pay.

  • Syncs to your group the next time you open the app
  • Choose the group and currency
Split

Not everything is split equally.

Someone arrives a day late, someone doesn’t drink, someone only had half — Split Robot handles it.

Four ways to split

By ratio, by shares, by amount, or with adjustments.

Four hotel nights, and Kai arrived a day late: split by nights — Ann, Leo and Mia 4 shares each, Kai 3.

  • Several people can pay for one record
  • Give a category a default split, e.g. lodging always by nights
  • Record income (like refunds) and transfers between members
Hotel split by shares: three people ¥25,600, Kai ¥19,200
Settle

Who owes whom, at a glance.

Balances

What everyone paid, spent and still owes.

Positive means others owe you; negative means you owe. Every number is broken down into paid, spent and sent, so you can check it yourself.

  • Simplified to the fewest transfers
  • Prefer to pay back exactly who you owe? Turn simplifying off
Balances: Ann +$1,245.83, everyone else owes
Settle up and remind

Tap a debt, confirm the amount, done.

Someone hasn’t paid? Tap Remind and their phone gets a notification. For friends without the app, send the reminder through any messaging app.

Settle up: Mia pays Ann $557.97
Together

Everyone on their own phone, one shared book.

Live sync

Someone adds a record, everyone sees it.

Share an invite code or QR code and friends join in. Each record shows the total and your part: you lent, you owe, or not involved.

  • Members are notified of new, edited and deleted records
  • Add friends without the app as members, link them later
  • Works offline and syncs when you’re back online
Records: totals with what I lent or owe

FAQ

Is it free?

Recording, splitting and settling up are always free; the free version shows ads. Pro adds unlimited groups and photos, search, recurring expenses, app icons and themes, and no ads — monthly or annual, both with a free trial.

Do my friends need the app?

No. Add them as members and record for them; when they install the app later, an invite link connects them to that member.

Different currencies on a trip?

Yes. Record each expense in its own currency; stats and balances are converted to the group currency.

Will my data move to a new phone?

Sign in with Apple under Settings › Account & sync, then sign in with the same Apple ID on the new phone.

Does the app send money?

No. It records and calculates; pay back however you like, then tap “Mark as paid”.

Next trip, let the robot do the math.

No sign-up. Invite your friends and never reconcile receipts again.
