✓See what is coming. Rent, energy, phone, streaming, the gym: one list, a calendar of what is due, a warning before a free trial becomes a charge, and another before a contract ends and the price goes up.
✓Split it your way. Equally, by percentage, by shares, by income or by exact amount. A running tally of who owes whom, the fewest payments that clear it, and every amount you can take apart to see where it came from.
✓It never touches your money. Costs are added by hand, read from a receipt you photograph, or found in a statement you downloaded. A household you share is kept on a server in London, for its members and no one else.

Your data
Nothing about you is sold, shared or handed to an advertiser.
True of every app here. Beyond that they differ, and each app's own page says so in its own words: what it keeps, where, and its privacy policy in full.
With you
Your figures and your working
Your records and documents
Your plans and your notes
Your settings and your history

An advertising identifier
A bank login
Everything on the left stays on your phone unless you choose to sign in. Where that is offered, the app's own page says where the copy is held.
Used on its own, no app here has an account. Where one is offered it is optional and does one thing: it lets your records follow you to another device. Choose it and the app says where that copy lives. Decline it and, for most, the app makes no request in your name at all.
None of them connects to your bank. None moves money, places a trade or files with HMRC. They keep the record, do the arithmetic and show the working.
The shop and deal pages are the one part of this site that earns from advertising. Their links are affiliate links: to Amazon (as an Amazon Associate I earn from qualifying purchases) and to shops such as Machine Mart, GSF Car Parts, Tyres UK and Tower Housewares through the Awin network. If you buy through one, the shop pays us a commission at no cost to you. The shop learns only that you came from our link: we pass it nothing about you, and these pages set no tracking cookies of their own. How these pages earn.
Paid features are bought through the store you installed from. The apps never see your card.
Why we build them
Each one is built for something a person does regularly and would otherwise do in a spreadsheet or not at all. They are made to be opened on a phone in the middle of that job, so they are quick to reach, they show their workings rather than asking to be trusted, and they ask for nothing they do not need.
One App Company is an independent studio in the UK. The apps are the business, so there is no reason to keep anything about you.

Free to start. Pro where it exists. Nothing to sign up for.
A button that goes nowhere is worse than an honest gap. An app not yet on a store says so, and its button is not a link until the listing is public.
