Plain-text accounting for iPhone

Your money, in plain text, on your iPhone.

Twentry keeps your books in Ledger journals, simple text files you own, and computes balances and reports with Ledger 3.4.1, built into the app. No account, no cloud, nothing locked in.

Coming soon to the App StoreFree · iPhone with iOS 17 or later

Money flow: where the money came from and where it went

Home: net worth, getting started and your accounts, in the sample journal

Plain text in, real books out

Readable files you own. Real accounting on top.

Every transaction is a few lines of text in a file that belongs to you. Twentry runs Ledger 3.4.1 itself on the phone, and Ledger and hledger on your computer read the same journal.

Open the journal you already keep, or start a new one in a minute.
Ledger checks every change before it's saved.
The last 50 versions of each journal are kept, ready to restore.

On-device AI

Write it the way you'd say it.

Type a sentence, dictate a voice note or share a screenshot of a payment. Twentry proposes the entries; you check and confirm them.

Optional. The model runs on your iPhone and nothing from your journal is sent anywhere. It's downloaded once (2.5–4.6 GB), when you choose one.

Everything careful books need

And nothing you didn't ask for.

Bank statements

Import CSV and Excel files, and PDFs and screenshots on iOS 26. You check every line before it's saved.

Share from your bank's app

Share a payment's screenshot to Twentry, and it becomes an entry to check.

Your computer too

Sync with your own private GitHub repository; Ledger and hledger on your computer read the same journal.

Any currency

Accounts in several currencies, with prices, and totals estimated in your home currency.

Face ID lock

The app and its open screens hide behind Face ID or your passcode.

Three languages

English, Azerbaijani and Russian, in the app and for the AI.

Private by design.

Your journal stays on your iPhone, and in your own GitHub repository only if you connect one.

No account

Nothing to sign up for, and nothing to sign in to.

No servers

Twentry has no servers of its own. Nothing is uploaded to us.

No tracking

No analytics, no advertising, no tracking of any kind.

Questions

Do I need to know Ledger?

No. Start a new journal or look around in the sample one; Settings › About › How Twentry works explains the idea in a minute. If you already keep a Ledger journal, open it from Files: the app works on a copy.

Which iPhones run the AI?

The AI runs on the iPhone itself, so how well it works depends on your iPhone's memory: the larger, more accurate models need more. The app suggests the most accurate model that fits your iPhone and marks the ones that may not. On an iPhone with little memory no model may fit; everything else works on any iPhone with iOS 17.

What does it cost?

Twentry 1.0 is free, with every feature included. There are no ads and no subscriptions.
