Calculator with Memo & Tax
MemoCalc Pro
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Swipe any result up to save it as a memo. Add them up, color-code them, and keep your numbers where you can see them. Tax and discount rates are fully customizable.
MemoCalc Pro combines a calculator and a memo pad in one app.
Save any result as a memo, line several of them up to compare, and add them together. Great for closing the register, expense reports, household budgets, and shopping — anywhere you want to keep your numbers while you calculate.
■ Key features
• Swipe a result up to save it as a memo
• Place memos freely and drag them around
• Show the total of several memos with one tap (Σ total bar)
• Sales tax (10% / 8% / 0%) in one tap — add your own custom tax rates
• Discount calculation (5% to 50% OFF and more) — add your own custom discount rates
• Color labels to sort and group your memos
• Calculation history
• Light / Dark themes, Japanese / English
■ Free and Pro (one-time purchase)
The free version saves up to 4 memos and shows ads. Upgrade to Pro (one-time purchase) to save up to 50 memos, use color-group management, and remove ads. Pay once and keep it forever — no subscription. When you change devices or reinstall, restore it for free with "Restore Purchase".
■ Privacy
Your memos and calculation history stay on your device and are not collected by the developer. The free version shows ads (Google AdMob); to deliver them, an advertising identifier and similar data are sent to Google (the app asks once for tracking permission, and every feature works even if you decline). The Pro version shows no ads and sends no data for ads.
Calculate and keep track, more smartly.
