myRunning Tab

Keep the record yourself — or give everyone their own login

Split and track shared expenses — 50/50, or any way you agreed.

Most of it really is 50/50 — and then it isn’t. One of you has the bigger room. Half the group wasn’t at dinner. Someone is hosting, so they pay nothing toward the food. Right now it is a spreadsheet, a thread of texts, and a camera roll full of receipts.

Running Tab remembers how each category works — a girls’ trip split four ways, your child’s medical 70/30, rent by the room, one category not shared at all. Set the rules once and it applies them to every expense the same way, with the receipt on every line.

And it stays put: every entry is sealed when it’s written, so a correction is a new dated line rather than a quiet overwrite. You don’t have to take our word for that — anyone can check a record for themselves.

What it can do

Real arrangements, not just an even split.

Most splitting apps do halves and one-off custom splits. Running Tab holds the arrangement itself — every kind of cost, at its own rate, for as long as it stands.

A different rate for every kind of cost

One of you has the bigger room, so rent is not 50/50. Medical 70/30. Your own phone bill not shared at all. Set each one once — every expense after that files itself.

It works whether or not they join

Keep the record on your own and send everyone a plain link when you want to — each of them sees their own balance, the receipts and the maths in a browser, with no account and nothing to install.

Categories that are never shared — and say so

Mark eating out as yours alone, and a restaurant bill gets flagged before you save it rather than quietly landing on the balance.

Deductibles and thresholds, handled

The first $250 of medical each year is yours, then it splits. It resets on Jan 1 without you remembering.

More than two people

Up to eight, each with their own share of a category. Balances stay pair by pair, so it is always clear who owes whom — and never re-routed to save a payment.

Change a rule without rewriting the past

Switch medical to 70/30 today and last month's bills keep the split they were entered under. Running Tab says how many entries each choice moves before you pick.

Anyone on the ledger can question a line

Flag it and it stays flagged, with the reason, in the record and the export. Running Tab will not clear it for anyone else and will not decide who is right — that was never its job.

Agree before the money goes out

Ask, get a yes on the record, and the expense carries that answer when the bill turns up. The cheapest argument is the one that never starts.

Hand it what you already worked out

Upload the agreement, the email, the note you wrote on a napkin — Running Tab reads it and proposes the categories and rates for you to confirm.

How it works

Four steps. No spreadsheets, ever.

Start with two names

Everything splits 50/50 until you say otherwise — change any category whenever you like, and add anyone else sharing the costs.

Log what you spend

Snap the receipt and Running Tab reads it, or type it in. Your rules are applied the same way every time.

Send everyone a link

Each of them opens their own balance, the receipts and the math on their phone — no account, no app.

Settle up

Pay in Venmo or Zelle and record it here. Save a PDF any time you need the whole record in one file.

Someone sent you a link?

Open the one they sent you.

Starting a new record here would be a separate one they can’t see. If you’ve lost the link, ask them to resend it — it’s the same link every time. Or check a record you were sent →

Will they know I looked? They can see how many times the link was opened and when — never how long you looked, what you tapped, or where you are.
Can they see anything else of mine? No. Not your email, your address, your phone, or anything outside the costs you share.
Can they cut me off? They started the record, so they can put it away or reset the link. You can save your own copy at any time, and it stays checkable even then.
Can they change an old number? No. Entries are sealed when written — a correction is a new, dated entry, and anyone can check the whole record was never altered.
What if I do nothing? Nothing happens. There’s no deadline here, nobody is charged, and no one can take money through this. It’s a record, not a demand.

Safety by design

Neutral means neutral.

Running Tab takes no side. It leads with what's fair to every side, and it's deliberately missing the features that make a shared record feel like a contest — no messaging, no nudges, no scorekeeping.

Only what you enter — the costs you share, the rules behind them, and receipts you attach. Nothing else about your situation
No messaging, no reminders sent on our own, no nudging — just the record
Account numbers and ID numbers are stripped from anything shared or exported
It applies the rules you confirmed and shows its working — it never takes a side
It never re-routes who owes whom to save a payment — the record shows the exact truth between each pair, always
You don't have to take our word for it: every record is sealed so anyone can check, on their own, that nothing was altered

Stop trying to figure out the math.

A bill, not a scoreboard. Set your rules once and Running Tab applies them every time.
