Highlights

  • Pages open almost instantly. Budget now opens in under half a second instead of 7 seconds, and the Overview in a quarter of a second.
  • Your certificates, tracked properly. One portfolio per bank, each certificate with its own terms. Interest and maturity cash appear in your forecast, marked as estimates.
  • Match your bank in one step. Type the balance your bank shows. A small gap is settled with one adjustment, instead of ticking off every line.
  • Other people’s money stays out of yours. Mark cash you hold for family or friends, and expenses someone else paid for you. Your net worth and spending stay accurate.

New

  • Ask AI about your money. Export for AI turns any period into one workbook and a ready-made prompt for the AI you use. Nothing leaves your computer unless you send it.
  • A guided start. The Get set up card takes you through five steps, then gets out of the way.
  • Categorise many rows at once. Search “Talabat”, select the rows, and set one category for all of them.
  • Start fresh without losing anything. Open a new profile; the old one stays exactly as it was.
  • Export just the rows you need. Tick them and save them as a CSV.

Looks and feel

  • Lightning looks like Lightning. Our own fonts and logo, cards coloured by what each number means, and a Back button on every detail page.
  • Your month at a glance. A calendar shows spending and net cash flow by day and by month.
  • One date picker everywhere. Weeks run Monday to Sunday, and it works from the keyboard.

Fixed

  • Imports take minutes, not an evening. You answer once per name, not once per row: 17 questions instead of 43 in the sample year.
  • Overview and Budget agree. Both show the same amount left in your plan, and a small “!” marks any figure that’s an estimate.
  • Old prices are flagged. Anything last priced more than about two months ago is marked.
  • Dropdowns inside pop-ups work again.

0.4.0 beta 1

2026-10-01 · Still available

Highlights

  • Lightning on your Windows PC. Your data stays on your computer, in a profile locked with your password and a recovery key.

New

  • Import your bank statements. CSV files up to 5 MB, and you review every row before anything is saved.
  • Safe upgrades. Lightning makes a verified backup before every upgrade.
  • See which build you’re on. The version shows in the title bar and in Settings.

Looks and feel

  • The answer comes first. Key figures lead with the number, then one line of context.
  • Faster edits. Right-click a transaction for Save, History, Cancel and Delete.

Still Open

What we’re fixing next

  • A flat, or anything else under “Other”, can be counted twice in your holdings.
  • Adding something you already owned shows as a gain in your net worth.
  • Safe to spend doesn’t count bills due right after payday yet.
  • If you sell everything in a period, the Investments tab hides that period’s gain.
  • Bringing in your old data, and restoring a backup, aren’t in the app yet.
