Keep notes, sums and results together. Compare prices, split bills and convert units. Explore free samples; editing requires a monthly plan or a one-time purchase.
A calculator that keeps your notes. Write calculations alongside context, keep the results and return to them later. TAPE1 brings everyday sums, discounts, split bills, unit conversions and shopping comparisons into one notepad.
KEEP THE REASON BEHIND THE RESULT
Save calculations with notes so you can remember what each amount was for. Search saved notes, copy results and export your calculations when you need to share them.
EVERYDAY CALCULATIONS, TOGETHER
• Arithmetic, percentages, discounts and splitting bills
• Japanese consumption tax, including reduced food tax rates
• Length, weight and volume conversions, dates and Japanese calendar calculations
• Compare prices and quantities on the same basis
• Save and search notes, copy calculations and export results
• Calculate from Home Screen widgets and Shortcuts
• A first-use guide to help you get started
Currency conversion uses Frankfurter daily reference rates, not live trading rates. Downloaded rates are cached on your device.
INPUT SUGGESTIONS WITH APPLE INTELLIGENCE
On supported devices, Apple Intelligence helps select relevant input suggestions on device. TAPE1's local engine performs the calculations.
Requires a supported device with Apple Intelligence enabled. Language and region availability varies. Standard suggestions and calculations remain available without Apple Intelligence.
PLANS AND ACCESS
Download and browse preset examples for free. Custom input, editing, shopping comparisons and widget calculations require an active purchase. Viewing, copying and exporting existing notes, settings, purchase restoration and support remain available without a purchase.
Choose a monthly subscription or a one-time lifetime purchase. See the App Store and in-app purchase screen for local prices. Eligible users can try the monthly plan free for seven days. It then renews automatically at the monthly price. To avoid being charged, cancel in Apple settings at least 24 hours before the trial ends. The lifetime purchase has no automatic renewal or free trial.
Everyday calculations run on device. When you send feedback or rate a result, the selected content is sent for support. No advertising or tracking.
