About Cash Book

Cash Book is an AI-driven expense tracker for iPhone that lets users log spending by voice, receipt photo, or keypad, with AI extracting the amount, merchant, tag, and date. It includes budgets, accounts, and insights, and does not require an account or bank connection; data stays on the device, with optional encrypted iCloud sync. The app supports 26 languages and 128 currencies. Voice and photo logging need an internet connection, while other features work offline. It is available after a 7-day free trial, as either a one-time purchase or an annual subscription.

Best for: iPhone users tracking personal expenses, people who want private, offline expense tracking, users who prefer not to link a bank account
