longbook for Mac

the complete cockpit — reports, cashflow, insights and spending, all on your desktop.

download for Mac
free · no account · macOS 12+

to use it on your Mac

1
your whole longbook is
it's just text.
2
move it to iCloud
and the Mac finds it on its own.

the real thing runs on your own devices, keeps your vault as plain files you own, and never connects to anything.
