Listub Debt Ledger review: IOUs, one-to-one loans and group expenses in three modes

Money between friends gets awkward when nobody keeps track. An IOU app like Listub Debt Ledger replaces the note that says 'Tom 40' with a dated, shared record of who owes whom. The module is part of Listub, the all-in-one organiser from Cologne-based Galveo, and it was the fourth module the team built, announced in April 2022.

This review is based on Listub's published module page, plan information and guides, not on hands-on testing. We look at the three modes, splitting and repayments, transparency, what the module deliberately does not do, and pricing.

What is Listub Debt Ledger?

Debt Ledger is Listub's module for money that moves between people rather than through a bank. When you create a room, you choose one of three modes, each with its own permissions, member rules and notices. The mode is then fixed, so it pays to pick the one that matches the real situation before inviting anyone.

Listub stresses that Debt Ledger is a record, not a bank. It does not connect to accounts, does not process payments and does not give financial advice. You decide what is owed and how it is repaid, and the app keeps the paperwork straight.

Solo, Contract and Group modes explained

The three modes cover the full range from casual to formal. Solo is a private record only you keep, ideal for quietly noting small amounts you have fronted. Contract is a one-to-one agreement that both people accept; the terms, date and acceptance are locked when the room is created, so nobody can rewrite the deal later. Group is for costs shared across several people, such as trips, flatshares and clubs.

That structure is the module's main strength compared with a simple IOU list, because a loan to a sibling and a weekend-away kitty need very different rules.

• Solo: private IOU record for yourself
• Contract: accepted 1:1 loan with locked terms
• Group: shared expenses with per-share settle-up

Splitting costs and tracking repayments

In Group mode you add a cost, choose who was in on it and split it evenly or by exact amounts. Everyone gets a net balance, and a direct repayment between two people closes it out. Flatmates can use it for utilities and the big grocery run, with each person marking their own share as paid.

Repayments work the same way across modes. You log a part payment or the full amount, the running balance updates and the history stays intact. Listub's advice is to log amounts while everyone still remembers the details, add a short note to each entry and settle up regularly to keep balances small.

Transparency: everyone sees the same numbers

In shared rooms, every member reads identical amounts, notes, dates and status. There is no private spreadsheet and no second version of the story, which is what makes money conversations shorter and less awkward.

Galveo AI helps capture entries quickly. Plain sentences such as 'I lent Tom 20 euros', 'Anna owes me for dinner' or 'split the taxi with Sara' become draft entries that you confirm before they are saved.

Pricing and platforms

Debt Ledger is included on the free plan, like every Listub module, and Solo mode works well there because it is private by design. Contract and Group rooms involve other people, so the room owner needs Premium or Family to invite them; members on the free plan can join rooms that a paying member shares and use them fully.

Premium adds cloud sync and sharing, three devices and up to 50 rooms as owner. Family adds three members, up to 400 rooms and up to 20 devices. Both are budget-priced, with launch pricing locked in for early subscribers. Listub runs on iPhone, iPad, Android, Mac, Windows and the web, which helps on group trips with mixed devices.

Debt Ledger vs Travel Hub expenses

Listub has two places for shared costs, and they serve different needs. Travel Hub includes a simple expense log for a trip, noting what was spent and who paid, which is enough for many holidays. Debt Ledger is the dedicated tool when balances need to be exact: Group mode calculates net balances with even or exact splits, and Contract mode formalises a one-to-one loan that both sides accept.

For a group trip with lots of shared bills, many travellers will keep the itinerary in Travel Hub and the money in a Debt Ledger Group room, both inside the same app.

Who should use Debt Ledger?

Debt Ledger suits friends who share trip and dinner costs, flatmates splitting household bills, families lending money to each other and small clubs with shared purchases. Its combination of private, formal and group modes is unusually flexible for a household app.

If you want an app that sends the money itself or connects to your bank, this is not it. If you want a calm, transparent record of who owes whom, it does that job well.

Frequently asked questions

Listub Debt Ledger handles the awkward side of shared money with clear structure: a private Solo record, an accepted and locked Contract for real loans, and a Group mode for trips and flatshares. It never touches your bank and never moves money, which keeps it simple and private. The fixed mode is worth noting, but for friends, families and roommates on iOS, Android, macOS, Windows or the web, it is a thoughtful IOU and split expenses app in 2026.
