## Description

Stop bouncing between a calculator and your notes.

Keisan Memo is a text calculator. Write “lunch 1,200 × 3” in a note and “3,600” appears at the end of the line as you type. Edit the numbers and every result updates.

- NATURAL WRITING: labels and math share the same line.
- JAPANESE-NATIVE: supports Japanese numerals, consumption tax phrases, and percentage discounts.
- TOTALS & VARIABLES: write 合計 to sum previous lines or define reusable values.
- UNIT CONVERSION: convert length, weight, and time inline.
- EXACT DECIMAL MATH: 0.1 + 0.2 is exactly 0.3.
- FREE AND UNLIMITED: notes, lines, templates, and text/CSV export have no paywall.
- ON-DEVICE NOTES: calculations and note storage stay on the device. Note contents are not sent to the advertising provider.

The free app displays one adaptive banner at the bottom. A ¥100 / $0.99 non-consumable purchase permanently removes the banner. It is a one-time purchase with no subscription and no automatic renewal. Ad delivery uses Google AdMob and an internet connection; advertising identifier use follows your iOS tracking permission.

Note: results are estimates for personal memos and are not accounting, tax, or legal advice.
