Free Offline double-entry ledger for Android Offline ledger for Android

Your money, your phone, nobody else.

A double-entry ledger for everyday money. No account to open, nothing reported to anybody, and books that cannot quietly stop balancing.

Why this one

Private by design, correct by design

Where your data goes, whether the totals hold, and whether it needs a network at all.

It has nowhere to send your money data

The app has no server, so your entries have nowhere to go. It uses the internet for one thing only: checking for a new version and downloading it. Android’s own backup is separate — the privacy page says what it carries.

Every amount is written twice

Real double-entry, the way an accountant keeps books: money leaving one place always arrives somewhere. The Trial Balance page shows the two sides agreeing, so a wrong total is caught instead of carried.

It works with the phone in flight mode

Nothing waits on a network. The ledger is encrypted on the phone, backups are files you keep yourself — with a password if you choose one — and the app locks behind a PIN or your fingerprint.

Features

Everything it does, at a glance

How to install

Why it is not on the Play Store

It is published here instead, as a file you download and install yourself. Your phone will warn you about that, because a phone cannot tell one unknown file from another. What it can tell you is whether the file is exactly the one published — every release carries a SHA-256 fingerprint, and the install guide shows how to check it.

Three permissions. Each one has a single job.

Questions

Before you install

My phone warned me. Is it safe?

Android shows that warning for every app that does not come from the Play Store, because it cannot tell one unknown file from another. Play Protect then scans this one and says it looks safe. To be sure the file is exactly the one published, the install guide shows how to check its SHA-256 fingerprint.

Does it cost anything?

No. It is free, with no ads and no account to open.

What if I change or lose my phone?

Your ledger is encrypted on this phone, so it does not move to a new one on its own. Before you change phones, save a backup file from the app’s Backup page — with a password, if you like. On the new phone, install the app, set a PIN, then restore the file from the Backup page. Keep a copy of that file off the phone too, in case the phone is lost.

Does it need the internet?

No. Everything works offline. It goes online only to check for a newer version, and to download it when you say yes.

Is there an iPhone version?

No. It is for Android only, version 7.0 and up.

How do I get updates?

The app tells you when a new version is out, downloads it when you say yes, and installs it. You do not need to come back to this page.
