Double-entry postings
Debits and credits post together against your chart of accounts. Amounts are held as exact integer cents — no floating-point money.
PRIVATE BOOKKEEPING · IPHONE · IPAD · DESKTOP WEB
Your books, in your own file.
Bookkeeping on your phone, with a companion website for Mac and PC — using the same .ledgerlyne file you keep in your own storage.
Ledgerlyne keeps company books with real double-entry postings and exact integer cents. Company and financial records are not stored in a Ledgerlyne cloud database — they stay in a file you choose, in your own iCloud Drive, Dropbox, or any other Files location.
Already using Ledgerlyne? Open ledgerlyne.com/app on your computer and sign in with the same Apple account. Your subscription includes the desktop companion.

Saved in your iCloud Drive, Dropbox, or any location you can reach through Files or Windows. The file moves when your storage provider moves it.
Before saving, each device checks the file's revision number. If the file changed somewhere else, Ledgerlyne tells you instead of writing over it — review the newer version before continuing. Keep regular backups of important records.
WHAT LEDGERLYNE DOES
Real bookkeeping, not a spending tracker.
Every entry posts to both sides of the books. Money is stored as exact integer cents, never as floating-point numbers, so amounts do not drift from floating-point rounding.
Multiple companies
Keep several separate company profiles, each with its own books, accounts and registers.
Registers and transactions
Record checks, debits, deposits, transfers and opening balances in the registers you set up.
Reconciliation
Reconcile each register against the statement so the books and the statement agree.
CSV and Excel import
Bring history in from a CSV or Excel file. Rows with invalid dates or amounts are rejected before anything posts, and a repeated import is detected and skipped.
CSV export
Export data as CSV through Apple's share sheet to send it where you need it.
HOW YOUR DATA IS STORED
Ledgerlyne does not keep your books on our servers.
Ledgerlyne does not store company or financial records in a Ledgerlyne cloud database. Your books live in a .ledgerlyne file in a location you choose, and every device opens that same file.
The file is yours
Pick a folder in iCloud Drive, Dropbox, or any other location available through Apple's Files picker or Windows. That is where the book lives.
- iPhone, iPad and the Windows app open the same file
- Your storage provider is the one moving the file between devices
- You can copy, back up or move the file like any other file you own
Safe saves, not silent overwrites
Because the file is shared rather than streamed, Ledgerlyne checks a revision number before every save.
- If the file changed elsewhere, you are told before anything is written
- One device never silently overwrites another device's work
- Nothing is lost when two devices worked on the same book
Ledgerlyne is file-based. Changes appear on another device once your storage provider has finished putting the newer file there — it is not a live connection between devices.
REPORTS
The statements you actually get asked for.
Ledgerlyne builds its reports from the same double-entry records you posted, so the numbers trace back to individual transactions.
Profit & Loss
Income and expense activity for the period you choose.
Balance Sheet
Assets, liabilities and equity as of a date.
Trial Balance
Account balances with debits and credits side by side.
General Ledger
Every posting, account by account.
Tax summary
A summary view to hand to whoever prepares your return.
Integrity report
A check on the internal consistency of the book's records.

QUESTIONS
Ledgerlyne FAQ
Where are my books stored?
In a .ledgerlyne file in a folder you choose — iCloud Drive, Dropbox, or any other location you can reach through Apple's Files picker or Windows. Ledgerlyne does not store company or financial records in a Ledgerlyne cloud database.
How do my devices stay in agreement?
They open the same file. Your storage provider is what moves that file between devices, so a change shows up on another device once the provider has put the newer file there. Before saving, each device checks the file's revision number; if the file changed somewhere else, Ledgerlyne tells you rather than writing over it, so nothing is lost.
Is there a Mac app or a browser version?
No. Today Ledgerlyne runs on iPhone, iPad and Windows. A Mac version is not available yet, and there is no browser version of Ledgerlyne.
What do I need to use the Windows app?
Windows 10 or 11, 64-bit, a Ledgerlyne subscription, and Sign in with Apple. Both the setup installer and the portable build are on the downloads page.
Can I bring in history from a spreadsheet?
Yes. Ledgerlyne imports CSV and Excel files. Rows with invalid dates or amounts are rejected before anything posts, and if you import the same rows again they are detected and skipped.
Does Ledgerlyne connect to my bank or file my taxes?
No. Ledgerlyne is a recordkeeping tool. It has no bank connections, no payroll, no invoicing and no tax filing. You enter or import transactions, and Ledgerlyne keeps the double-entry books and produces reports.
