One Ledger, Not Two Copies
Your phone holds the ledger. Your PC borrows it when you sit down, so you never merge two versions.
Phone and PC
One Ledger. No Cloud.
Your phone holds the ledger and your PC borrows it over your own Wi-Fi, then hands it back. No account, no server in between.
Free to use. Windows and Android. No bank login.
How it works
Pair Once, Then Just Open It.
Three steps, and only the first needs any setting up.
Pair Once
OnceYour phone shows a code; type it on your PC. Both screens then show the same six digits, such as 370 548, so you know it’s your phone.
Borrow It
Any timeOpen it on your PC with the same password as on your phone. It arrives with every edit you made on the go, and your phone reads while you work.
Hand It Back
On closeClose Lightning near your phone and the ledger goes home. Away from it, your edits are sealed and wait for the next meeting.
What you get
Same Figures on Both Screens.
Encrypted, Over Your Wi-Fi
Both devices use the same password. They meet over your own Wi-Fi, so your money data never touches a server.
One Edits, the Other Reads
While your PC borrows the ledger, your phone reads. Edits made away from your phone wait, sealed, for the next meeting.
Good questions
Questions, Answered
Do I need an account to sync?
No. You pair once by typing a code from your phone on your PC. There is no sign-up and no email.
Does it sync over the internet?
No. Your phone and PC need to be on the same Wi-Fi. Nothing goes through our servers, because we don’t have any for your money data.
Can I edit on both at the same time?
No. One device writes at a time: while your PC borrows the ledger, your phone reads, and the ledger goes back to your phone when you close Lightning near it.
Which phone and PC do I need?
An Android phone and a Windows PC. The Android beta is an APK for now; Google Play comes later.
What if my phone is away when I close the PC?
Your edits are sealed on the PC and wait. The next time the two meet, the ledger goes home.
