A calculator that remembers what your numbers were for. "Wait, what was this $385 for?" A normal calculator only keeps the answer. CalcMemo puts every calculation into a note, and lets you add a line of text in between. Quotes, budgets, splitting the bill, trip costs: come back later and you can still see what you calculated and why. ■ Made for • Quotes: unit price × quantity, with item names • Budgets: monthly bills in one folder, with a total • Splitting the bill: head count and rounding, all on record • Loans: compare monthly payments and total interest • Due dates: a monthly reminder on the 25th to pay rent ■ Calculator and notes on one screen Notes on top, calculator below. Every "=" adds the expression and answer to the note. Add headings and memos anywhere to keep it readable. Ans button recalls the last answer. ■ Scientific functions and statistics The f(x) tab adds trig, logs, powers, factorial, parentheses and memory (M+ M− MR MC). Select calculations in a note to see their sum, mean, max, min and standard deviation. ■ Money math built in • Loans (including balloon payments) • Loan prepayment simulator (Pro) • Savings plan (Pro) • Compound interest • Profit margin and discounts • Bill splitting with rounding • Sales tax • Date and day counting • Unit conversion (length, weight, temperature, area, volume, speed, fuel economy, time) Save any result to your note in one tap. ■ Reminders and widgets • Note reminders (Pro): once, daily, weekly or monthly. Tap the notification to open the note • Daily reminder: a nudge at the same time every day • Home Screen widgets (Pro): pinned notes, a folder, or one note's answer ■ Organized like a notes app Folders, pinning, grouping by date, reordering, moving between folders, and search across all notes. ■ iPad three-column layout Folders, notes and calculator on one screen, with a calculator you can float anywhere. ■ CalcMemo Pro (one-time purchase) Buy once, keep it forever.
