Have you ever memorized or written down numbers while performing complex calculations? Intuitive Memory Calculator solves this problem with multiple memory slots that make it easy to store and retrieve numbers for multistep calculations! Simply tap a memory slot to store a number and tap it again to retrieve a stored number unlimited times. When you ready to clear a memory slot, swipe up on that slot and tap Delete. Additionally, you can now access 25 of your most recent calculations. Many traditional calculators with memory would have up to five buttons (MS, MR, MC, M+, or M-) just to allow you to keep track of one number! Intuitive Memory Calculator has three memory slots which allow you to keep track of three different numbers and each slot was designed to take up no more space than any other button in this calculator.

Apple Notes, if it could do math. Type rate = 45 on one line and rate × hours on the next, and the answer appears in the margin as you type. Every line that looks like a calculation resolves instantly. Everything else stays prose. No account. No servers of ours. Nothing to sign up for. WRITE MATH LIKE A SENTENCE • 20% of 300, 200 - 10% — percentages, markups and discounts the way you'd say them • 100 usd in eur, $50 + 20% — live currency rates, formatted as money • 10 km + 5 m in miles, 6 m / 2 s → 3 m/s — real unit algebra, not string replacement • today + 21 days, 3 days + 12 hours — dates and durations that count themselves A NOTE THAT ADDS ITSELF UP • Name a value and reuse it: rate = 45, then rate × hours three lines later • sum a block for budgets, receipts, invoices and quick tallies • round, sqrt, pi and the rest, for when a note needs to be a little smarter STILL A REAL NOTES APP Folders, pinned notes, search, a home-screen widget, Recently Deleted, and a quick scratch pad one tap from anywhere. Light and dark themes. Available in English, Russian and Kazakh — and the calculator understands all three, because the parser does, not just the interface. PRIVATE BECAUSE OF HOW IT'S BUILT Every calculation runs on your device. Your notes live in local storage on your iPhone, not in an account with us. All the math, unit conversion and currency work is free, forever — there is no calculation behind the paywall. BUILT FOR Freelance quotes and invoices. Monthly budgets. Travel money. Recipe scaling. Any moment you'd reach for a calculator and then forget what the numbers were for. DÄPTER PLUS Unlimited notebooks, and iCloud sync across your iPhones through your own Apple account. Monthly, yearly, or a one-time lifetime unlock — pay once and you're done. Plus is what keeps däpter independent: no ads, no investors, no data sold.
