How can we help?

Tomodomo helps you split bills and track shared expenses with friends — whether that's one dinner or a whole multi-venue trip. You create a tab, add the people involved, add what was bought, and Tomodomo works out who owes what.

A tab is a shared bill or trip. When you create one you choose:

• Single tab — one venue, one bill. Good for a single dinner, a coffee run, one bar.
• Multiple tabs — several venues, same group of people, one tab per place you spend money. Good for a bar crawl, a weekend trip, or a shared house.

You create a local profile (a name, and optionally an email + PIN) the first time you open the app — there's no sign-up, no email verification, and no server-side account. Everything lives on your device.

No, for the core app — adding tabs, bills, items, and settling up all work fully offline. A connection is only used for a few optional extras: looking up a venue's logo, fetching currency exchange rates for multi-currency trips, and processing a Tomodomo Pro purchase. None of these block you from using the app offline.

Yes. Tomodomo doesn't have a backend or an account system, so there's nothing for your bills, friends' names, or photos to be sent to. Everything is stored locally on your device. A few narrow exceptions (venue logo lookups, exchange rates, and Apple's own purchase processing) send a small, specific piece of data to a third party to make that one feature work — see the Privacy Policy for the full breakdown of exactly what leaves your device and when.

When creating a tab you pick from your existing friends, or add a new one on the spot. You can add more people to a tab later too — from the tab's cogwheel (settings) menu, choose “Add friends.” If everyone you know is already in the tab, that screen lets you create a brand new friend right there instead of leaving you stuck.

Yes — swipe an item in the list to edit its name, price, or category. If you correct a price on an item that's split “by amount” or “by percent,” Tomodomo automatically rescales everyone's portion so it still adds up to the new total; you don't have to manually redo the split.

Yes, both are editable after the fact from the tab's settings.

These are one-tap ways to add a tip, a service charge, or a cover charge to a bill without typing it in as a regular menu item. Each can be a fixed amount or a percentage of the subtotal, and split either equally or proportionally to what each person ordered. A cover charge (a flat per‑person entry fee) is split equally by design.

Every item can be tagged with a category (Food, Drinks & Alcohol, Transport, etc. — a fixed list, so “Beer” and “beer” always count as the same thing). This powers the spend-by-category breakdown on the Overview tab — see what you spent on what, and who's actually driving the spend in a given category.

There are two separate things to settle:

• Paying the venue. Whoever actually paid the bill gets reimbursed by everyone else. You can settle the whole table's outstanding amount in one tap, or (if some people already left, or want to pay just their own share) select only certain people to pay.
• Settling up between people. Once the venue's been paid, Tomodomo works out the smallest number of payments needed between the group so everyone ends up even, and lets you record each payment as it happens.

Once a group has three or more people, “who pays whom” for a minimal set of transfers isn't always a single well-defined answer the way it is for two people — the same total balance can be settled by different pairs of payments. Rather than guess, Tomodomo shows a read-only summary (in the Reports tab) of your overall spend and net position across every tab, and lets you export or save it — but the actual settling still happens tab by tab, where “who owes whom” is unambiguous.

Shaking your device is a shortcut back to whichever bill you were most recently working on that still has money owed to the venue — useful for jumping straight back into an active tab without navigating through the tab list.

Everything needed to split bills and settle up: unlimited tabs, unlimited people, item editing, tips/charges, categories, venue logos, multi-currency, and a simple one-number budget per tab.

• Envelope budgeting — split a tab's budget across its individual bills, or across the people in the group, instead of one lump total.
• Category & per‑person spending caps — set a limit on a specific category (like drinks), or give each person their own budget for the trip.
• Export reports — turn a tab's full history into a PDF or CSV, including every bill, item, and receipt photo.
• Save & revisit reports — freeze today's numbers into a saved report, so later changes to your tabs don't change what was recorded.

Through your Apple ID account settings, same as any other subscription — Tomodomo's own Settings screen links directly there. Tomodomo doesn't process payments itself, so refunds and cancellations go through Apple.

A dashboard summarizing your spending and net position across every tab you're part of, converted into one home currency for easy comparison. You can filter it, export it as a PDF/CSV, or save a snapshot of it to revisit later without it changing as your tabs do.

Closing a tab (from its cogwheel menu) archives it — it moves to the bottom of your “My Tabs” list instead of cluttering the top, but nothing is deleted and you can still open it.

No — removing someone only takes them off the tab's current roster going forward. Any bills, splits, or payments they were already part of stay exactly as they were; Tomodomo never rewrites history.

Yes — this can be turned on in Settings, using your device's own biometric check. Tomodomo never sees your fingerprint or face data itself, only a yes/no result from iOS.

Since there's no account system or server, Tomodomo's developer has no way to reset a PIN remotely. If you're fully locked out, reinstalling the app will let you create a new local profile, though this starts fresh rather than recovering your old data.
