What you get free, and what a subscription adds.
You can track up to ten assets and liabilities combined, with every feature available — all reports, multiple currencies, documents, iCloud sync, and App Lock. Your current usage is shown in Settings next to Subscription, so the limit is never a surprise.
A subscription removes the ten-item limit. It is offered monthly or yearly, billed through your Apple Account, and you can manage or cancel it from Settings › Subscription at any time. Prices are shown in your own currency.
Apple retries for a grace period, during which nothing changes and you keep full access. The app shows a banner asking you to update your payment details, and links straight to where you can fix it.
Your records remain yours. Nothing is deleted and nothing is hidden — everything you have entered stays in the app and in your iCloud, and you can still read it and run reports.
