📖 User guide

Calculates the split for trips and outings, with no sign-up needed.
Just log what each person paid, and it works out who owes whom, automatically.

🎉 Getting started

This site helps you record the money people paid on trips, dinners and events, and settle up afterwards. There is no login and no account.

When you create a "group", you get an address (a PayID) just for that group. Share the address and everyone can see the same screen and log expenses.
As you log expenses, the app shows each person's balance and the way to settle up with the fewest transfers.
It works on phones and computers. Use "Language" at the top right to switch between 日本語, English, 한국어, 中文, Tagalog and Bahasa Melayu.

The group screen: budget, expense list and settlement

It takes three steps.

Create a group in 🆕 Create a new group.
Whenever someone pays, log it with 🧾 Add expense.
Check 💸 Where things stand and send the amounts shown.

🆕 Creating a group

Fill in 🆕 Create a new group on the home screen and press Create group.

🦆Group name: a clear name such as the trip name (up to 60 characters).
💰Currency: the currency used in the group. Common currencies are at the top and all currencies are below. If you choose Japanese yen (JPY), amounts are shown in yen.
✏️Edit/delete window in minutes (0 = no limit): how many minutes after posting an expense can still be edited or deleted. The default is 5; enter 0 to allow edits at any time.
🦀Members: one name per line (up to 50 people, 30 characters each). You can add or remove members later.

💡 The currency can be changed only while the group has no expenses (✏️Change currency on the group screen). You can rename the group with the ✏️ next to its name.

🧾 Adding an expense

Press 🧾 Add expense on the group screen to open the form.

💳 Paid by: choose the person who actually paid.
👥 Paid for: choose the people who share this cost. Select / clear all selects or clears everyone.
🧾 Description: a short note you will recognise later, such as "Lunch" or "Taxi" (up to 100 characters; required).
🏷 Category: chosen automatically from the description. You can change it, or leave it as "None".
💰 Amount: the amount paid. Up to 2 decimal places are kept; anything beyond is dropped.
Press Add to finish.

Press 🧮 Open calculator under the amount to open a calculator. You can calculate while watching the formula, such as "1200+850×2". Press "=" and the result goes into the amount field.

💡 You can also attach a 📷 Receipt photo (next section).

📷 Receipt photos

You can attach one photo to each expense. Press Add photo and take a picture or choose one from your photos. It is automatically compressed before it is sent.
Expenses with a photo show 📎 in the list. Tap the expense to open it and see the photo. Tap the photo to enlarge it on screen; tap again to see it at full size.
You can add or delete a photo within 24 hours of creating the expense. Delete photo asks for confirmation and then removes it.
A group can hold up to 100 photos. Photos are kept for 1 year and then deleted automatically.

⚠️ Everyone in the group can see the photos. Be careful not to include card numbers or personal information.

✏️ Editing or deleting an expense

Tap an expense in the list to open ✏️ Edit expense. Change what you need and press Update.
While a countdown such as "00:00 left" is shown at the top, you can change the amount, payer, people and description, or delete the expense. The time is the number of minutes set when the group was created (0 means any time).
After that, you can still change the category and the photo (within 24 hours of creation).
To remove an expense, press 🗑️ Delete this expense.

📜 The expense list (NEW and filter)

The expense list with NEW badges and the filter

In 📜 Expenses, the newest expenses come first, grouped by day. Phones show 5 per page; computers show more to fit the screen. Use Next and Previous to move between pages.
Expenses added or changed within the last 24 hours get a NEW badge.
Expenses that were entered while offline and sent later get an Added offline mark on the line below the expense name.
Open 🔎 Filter to narrow the list by keyword, category, payer or dates. Settlement and totals are still calculated from all expenses.

💸 Reading the settlement

💸 Where things stand shows the current result.

The settlement and each person's balance

💰Who pays whom: who should send how much to whom so that everyone is even. It is calculated to need as few transfers as possible.
💰Balance per person (+ receives / − pays): each person's balance. + is money to receive and − is money to pay.
For groups in a foreign currency, an approximate amount in yen ("≈ ¥") is shown next to each amount. It uses a daily reference rate, which differs from real exchange or card rates.
Leftover amounts that can't be split evenly are handed out one cent (0.01) at a time, starting with the first person in the order members were added. The total always matches.
In yen groups, decimals are shown only when a fraction actually appears.
When everyone is settled, 🎉 All settled up! is shown.

📊 Totals by category and by day

📊 By category shows each category's total and share as bars. Open "Totals by day" to see each day's total.
Expenses without a category are grouped under ❔ Uncategorized.

💰 Budget

Use 💰 Set budget below the group name to set a budget for the whole group (anyone can change it).
Once set, a bar shows how much has been spent and what is left. It turns yellow above 80% and red when you go over.
If you also enter the trip's start and end dates, a daily allowance is calculated from what is left.
To remove the budget, press Delete budget.

👥 Adding and removing members

Add a member in 👥 Members: enter a name and press Add.
A member who isn't in any expense yet can be removed with 🗑️. Members who appear in expenses can't be removed.
If someone joins later, add them as a member and include them in 👥 Paid for for new expenses (past expenses are not changed).

💱 Currency and the yen estimate

You choose the group's currency when you create it. It can be changed only while there are no expenses.
In groups that don't use yen, an approximate amount in yen ("≈ ¥") is shown next to each amount. The exchange rate is updated automatically once a day.
If you actually paid in another currency, enter the amount converted into the group's currency.

🌐 Language

Use "Language" at the top right to choose the display language. It is saved in this browser, so the site opens in the same language next time.If you opened the group before leaving while online, you can switch languages even without a connection.

📲 Offline use and push notifications

Add the site to your home screen to open it like an app. Open the group you want first, then add it: the icon will open that group directly and be named after it (you can add one for each trip). On iPhone, use Safari's Share button and choose "Add to Home Screen". On Android, use the browser menu and choose "Add to Home screen" or "Install app".
On iPhone, opening from the home-screen icon uses separate storage from Safari. After adding the icon, open the group once from the icon while you are online.
Even without a connection (for example in airplane mode), a group you opened once while online still opens, and you can add expenses. Please open the groups you need before you leave (this works in the same browser even if you haven't added the site to your home screen).
If you press Add while offline, the expense is saved on this device and shown as Unsent. It is sent automatically when the connection is back.Tap an Unsent item to correct it (you can also discard it from that screen). If nobody is selected under 👥 Paid for, an error appears even without a connection.
Offline, the screen says "When offline, you can only add expenses." The past expense list, settlement, members, budget and the like are hidden, and only adding expenses is available. Please edit, delete and make other changes where you have a connection.
Press ⭐️ Offline & push notifications ⭐️ on the group screen (phones) to see how offline saving and push notifications work. Turn on the 🔔 Push notifications switch there to start receiving notifications on this device (you also need to allow notifications on your device).
You are notified when, in that group, an expense is added, changed or deleted, or a receipt photo is added. Your own actions are not notified, and neither are changes to members or currency.
On iPhone, notifications work only when you open the site from the icon added to the home screen (iOS 16.4 or later); the switch cannot be used in the Safari browser itself. The switch is set per group and per device.

The home-screen icon (named after the group)

💡 On the group screen, press ⭐️ Offline & push notifications ⭐️ (phones only) to see the offline steps and the push notification explanation and switch in a small window with pictures.

❓ Troubleshooting and limits

A PayID doesn't open: check for typos or extra spaces.
I can't edit or delete an expense: the number of minutes set for the group has passed. The category and photo can still be changed afterwards.
I can't remove a member: that member appears in an expense.
Amounts have decimals: the split left a fraction. In yen groups, decimals appear only when there is a fraction.
I can't attach a photo: more than 24 hours have passed since the expense was created, or the group has reached its limit (100 photos).
An expense stays Unsent: it is sent automatically when the connection returns. When you are online, press Send now.

Each group can have up to 50 members, 3000 expenses and 100 photos.
