What’s new
Notes for Lightning 2.1.2
Plain words, from the release notes. The full list is in the release log.
More Ways To Import A Statement.
Review Excel worksheets and more CSV formats, keep rows with the right account, and review up to 500 rows per page.
A Clearer Phone.
Move between Home, Budget, Add, Activity and Money from the tab bar. See what needs you and keep daily spending figures consistent with the PC.
Clearer Arabic.
Import reviews, date ranges, counts and delete confirmations read correctly in Arabic.
Install
Three Steps, and You’re In.
No account, and no bank password.
On your PC
Unzip the file into a new folder and open Lightning.exe inside it. Nothing to install, but Windows needs Microsoft Edge WebView2.
On your phone
Open the downloaded file. Android asks once to let your browser install apps: allow it, then tap Install. Download it only from this page.
Pair the two
Open both apps on the same Wi-Fi. The phone keeps the ledger and the PC borrows it, encrypted and with no server.
Release downloads

Sample data
Want to Look Around First?
Start with the downloadable CSV year, or load one of four ready-made profiles inside Lightning. Both use fictional data in an empty profile; your own statements work the same way.
- Sample year: download and unzip the sample pack.
- Create or open an empty profile in Lightning.
- For the sample year, create the accounts and import
cib-payroll.csvfirst, then the remaining files. - For Amr, Abdelrahman, Menna or Fatma, choose a profile on Lightning’s welcome screen and select Load sample.

App appearance
Try Dendera.
Open Settings → Appearance and choose Dendera or Dendera, night. It applies immediately. Choose Lightning default to switch back.
Free and unlocked themes save with the profile. To keep a paid theme: buy it on the Marketplace, press Get app code on its card, then paste the code in Settings → Appearance → Unlock a theme you bought. Do this once per profile: the profile’s other devices unlock by themselves. Your other profiles unlock with their own codes at no extra cost, up to 10. The store must enable the app release before it can issue a code.
One Dendera website purchase includes its day and night looks across this website and For Geeks. See the live price and the steps in Use it in the app.
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 gets better with every release.
