Cenno is an offline expense tracker for iPhone and iPad. No account, no ads and no bank connection required. Record everyday spending while keeping control of your ledger. Start with an amount or an expression such as 24+3.5. Reuse templates, record several entries in a row, attach receipt photos, and search merchants, notes, tags or amounts locally. Keep monthly and category budgets, carry unused amounts forward, and review accounts, credit cards, assets and liabilities. Ordinary bookkeeping includes transfers and refunds linked to an expense. Your ledger is processed on device and is not uploaded to the developer. Free, optional iCloud sync uses your own iCloud container and is off by default. Feedback is sent only when you choose to submit it. Free everyday tracking includes unlimited basic records, budgets, accounts, refunds, iCloud sync, CSV export and restorable backups with receipt attachments. The optional piggy-bank activity records savings from skipping a takeaway; no real purchase or transfer takes place. Optional Cenno Pro adds statement import, multiple ledgers, advanced reports, recurring entries, the reimbursement center and personalization. Choose a yearly subscription or one-time lifetime purchase; current local prices are shown by the App Store. Purchases work on iPhone and iPad. Users who bought version 1.0 receive Pro lifetime in 2.0. Interface: English, Simplified Chinese and French. Light and dark appearance. Requires iOS 17 / iPadOS 17 or later.
