About

Type an amount, then tap a category. That is a line in the book.

Leave the amount blank and tap a category to repeat the last amount you used there, with the same note, on the date shown.

A Saved line appears for a few seconds. Tap Undo if the last tap was a mistake.

Out is spending. In is income. A note is optional.

The large number is what remains of your monthly cap. If there is no cap, it is what you have spent.

A quiet line under that figure compares this month’s spending to the month before.

Arrows on the month name move backward and forward.

Left is money in. Center is the month. Right is where it went, plus Kept — income minus spending.

Band thickness is the amount. Smaller categories fold into Other. Hover or tap a band for the exact figure.

Each category’s spend, set against its cap if you gave it one. A mark in oxblood means the cap is crossed.

The lines, grouped by day. Tap a line to change it, delete it, or Repeat it into the month you are viewing.

Cash flow, This month, and Activity each fold from their heading. When closed, a short total stays on the row. Ledger remembers which ones you tucked away.

Set an overall monthly cap, and optional caps per category. Tap a category name to rename it. Add your own labels for spending or income.

Export CSV writes the whole book to a file. Clear all data removes entries, budgets, and custom categories from this device.

Ledger opens with a sample month so the pages are not empty. Tap Clear example data on the home page to start with a blank book. Categories stay; the sample lines and sample caps go.

The moon and sun switch paper and night paper. Ledger follows the system until you choose.

Nothing is uploaded. The book stays in this browser on this device. Opening Ledger somewhere else starts a different book.
