Every line that looks like a calculation resolves instantly.\nEverything else stays prose.\n\nNo account. No servers of ours. Nothing to sign up for.\n\nWRITE MATH LIKE A SENTENCE\n• 20% of 300, 200 - 10% — percentages, markups and discounts the way you'd say them\n• 100 usd in eur, $50 + 20% — live currency rates, formatted as money\n• 10 km + 5 m in miles, 6 m / 2 s → 3 m/s — real unit algebra, not string replacement\n• today + 21 days, 3 days + 12 hours — dates and durations that count themselves\n\nA NOTE THAT ADDS ITSELF UP\n• Name a value and reuse it: rate = 45, then rate × hours three lines later\n• sum a block for budgets, receipts, invoices and quick tallies\n• round, sqrt, pi and the rest, for when a note needs to be a little smarter\n\nSTILL A REAL NOTES APP\nFolders, pinned notes, search, a home-screen widget, Recently Deleted, and a quick\nscratch pad one tap from anywhere. Light and dark themes. Available in English,\nRussian and Kazakh — and the calculator understands all three, because the parser\ndoes, not just the interface.\n\nPRIVATE BECAUSE OF HOW IT'S BUILT\nEvery calculation runs on your device. Your notes live in local storage on your\niPhone, not in an account with us. All the math, unit conversion and currency work\nis free, forever — there is no calculation behind the paywall.\n\nBUILT FOR\nFreelance quotes and invoices. Monthly budgets. Travel money. Recipe scaling. Any\nmoment you'd reach for a calculator and then forget what the numbers were for.\n\nDÄPTER PLUS\nUnlimited notebooks, and iCloud sync across your iPhones through your own Apple\naccount. Monthly, yearly, or a one-time lifetime unlock — pay once and you're done.\nPlus is what keeps däpter independent: no ads, no investors, no data sold.\n\nTerms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/","bundleID":"com.shystudio.dapter","appiconURL":"https://is1-ssl.mzstatic.com/image/thumb/PurpleSource211/v4/24/5f/6c/245f6c97-932d-bdb6-282c-c4f262b6a3c6/Placeholder.mill/1024x1024w.webp","formattedPrice":"Free","appUpdated":"2026-10-12T13:15:25.000Z","appReleased":"2026-07-11T07:00:00.000Z","version":"1.8.0","platforms":["iphone"],"minOS":{"iphone":"Requires iOS 16.4 or later.","vision":"Requires visionOS 1.0 or later."},"topIAPs":[{"name":"Dapter Plus Yearly","price":"$4.99"},{"name":"Dapter Plus Monthly","price":"$0.99"},{"name":"Dapter Plus Lifetime","price":"$9.99"}],"languages":["EN","KK","RU"],"size":"64.9 MB","category":"Productivity","developerWebsite":"https://dapter.shystud.io/","screenshots":[{"platform":"iphone","url":"https://is1-ssl.mzstatic.com/image/thumb/PurpleSource211/v4/bd/94/a8/bd94a87f-f959-9177-8c2b-0cd48ae77e8f/Slice_1.png/1260x2736w.webp"},{"platform":"iphone","url":"https://is1-ssl.mzstatic.com/image/thumb/PurpleSource211/v4/e8/b3/23/e8b3235d-26de-d866-8d19-831da85e9bc6/Slice_2.png/1260x2736w.webp"},{"platform":"iphone","url":"https://is1-ssl.mzstatic.com/image/thumb/PurpleSource221/v4/12/63/4f/12634f3b-35d0-720e-58c2-6758a254d856/Slice_3.png/1260x2736w.webp"},{"platform":"iphone","url":"https://is1-ssl.mzstatic.com/image/thumb/PurpleSource211/v4/3d/fa/4e/3dfa4eee-1bb7-5e11-d987-980abb2e2990/Slice_4.png/1260x2736w.webp"},{"platform":"iphone","url":"https://is1-ssl.mzstatic.com/image/thumb/PurpleSource211/v4/ec/01/a5/ec01a518-0c6c-d87e-0b04-54fc1e2e9243/Slice_5__U00281_U0029.png/1260x2736w.webp"},{"platform":"iphone","url":"https://is1-ssl.mzstatic.com/image/thumb/PurpleSource221/v4/c5/09/3a/c5093aa6-6195-1cea-b551-b8e547e0940b/Slice_6.png/1260x2736w.webp"},{"platform":"iphone","url":"https://is1-ssl.mzstatic.com/image/thumb/PurpleSource221/v4/6d/52/bf/6d52bf3b-4774-9b86-2781-47538ce91dde/Slice_7.png/1260x2736w.webp"},{"platform":"iphone","url":"https://is1-ssl.mzstatic.com/image/thumb/PurpleSource221/v4/bc/b7/d3/bcb7d389-0c19-8a93-2584-c685e20efe91/Slice_8.png/1260x2736w.webp"},{"platform":"iphone","url":"https://is1-ssl.mzstatic.com/image/thumb/PurpleSource221/v4/1a/c0/22/1ac022c3-d946-4c32-5bd7-f688b8dc12a0/Slice_9.png/1260x2736w.webp"},{"platform":"iphone","url":"https://is1-ssl.mzstatic.com/image/thumb/PurpleSource211/v4/c8/d7/16/c8d716df-eaaf-b38f-b3c0-cbdfbbba3fcc/Slice_10.png/1260x2736w.webp"}]}
