Lightning beta
Current Status.
Lightning is in beta on Windows, and ready to use with your own statements. The Android app is in testing. Learn the steps with a sample year if you like, then tell us exactly what should improve next.
Beta, and ready to use: your real statements are welcome. The release log lists what’s still open.
Why Lightning exists
What My Own Numbers Taught Me
When I started investing, I chased percentages. The returns looked exciting, until I looked at the actual amounts, and at the worry and risk that came with them.
I had logged every pound since I graduated and reviewed it each week. That log showed me something quieter: fewer Uber rides and Talabat orders, and a little more care when shopping, kept almost as much each month as my investments made. And it kept doing it, month after month.
None of this is new. Most good money books land in the same place: you can’t control much around you, but you can control your own habits, and habits compound.
Keeping that log by hand took hours every month, and it still never showed everything in one place. Lightning is the tool I wanted then: everything I own and owe, counted properly, so the habits are easy to see. It’s still early, and it gets better with every tester.

Beta downloads
Choose Your Lightning Version.
0.5.0 beta 1 is the newest Windows build; 0.4.0 beta 1 remains available too. Each app version has its own permanent download. We keep at least the three newest versions in the version archive. The Android app is in testing: the phone holds the ledger, a paired PC borrows it and hands it back over your own Wi-Fi, and bank SMS wait in review. It comes to beta testers next, then Google Play.

Can you import?
Can you tell what file to use and match columns without guessing?
Can you trust it?
Do review states and numbers make sense before anything is posted?
Can you act on it?
Do Overview, Budget and Cash planning give you one clear next move?
