RecordCalc: Calculator History

The ultimate tape calculator! Experience seamless adding machine logic, instant theme switching, and keep perfect track of all your calculations.

RecordCalc turns your calculator into a receipt printer. Every calculation is saved on a scrollable tape — never lose a number, never retype a total.

KEY FEATURES

• INLINE EDITING — Made a typo on line three? Tap it, fix it, and the total and every line after it recalculates automatically.

• PDF EXPORT — Hand a clean, dated PDF to your accountant or client. Includes the full tape, subtotals, and a scannable reference code.

• THEMES — Six carefully crafted themes including "Ledger" (navy + gold, inspired by accounting books) and five others. Each has a light and dark variant.

• ICLOUD BACKUP — Calculations stay on your device by default. Turn on iCloud Backup and your tapes sync through your own iCloud account. We never see them.

• HOME SCREEN WIDGET — Your last tape, one tap away. Small, medium, or large. Pick exactly where you left off.

• SHORTCUTS — Trigger RecordCalc from Siri, pipe a number in, or hand off the open tape to your Mac with Handoff.

• DARK MODE — Follows your system theme. Or set it manually if you prefer.

• PRIVATE BY DEFAULT — No accounts, no analytics, no ads, no tracking, no third-party SDKs. Your calculations are yours.
