Puzzle Calculator

Puzzle Calculator — quotient and remainder together, with a layout you rebuild by hand 【Remainder mode】 Need “how many fit and how many are left” for pharmacy tablet counts, packing boxes, or warehouse picking? Turn on remainder mode and division answers appear as quotient and remainder together—like 10 ÷ 6 = 1 … 4. Switch it off anytime to return to ordinary decimal division. 【Remove ads (one-time purchase)】 On iOS and Android you can buy a one-time remove-ads option (about ¥480; your store shows the local price). Restore purchases if you reinstall. Every calculation feature works before you buy. The remove-ads purchase is for the store apps only; the web app (calc.inccc.jp) stays free with ads. ■ Freely customizable button layout Long-press a button, then drag to move it. Put your most-used keys up front and hide the rest. Layouts save automatically and restore next launch. Choose 1–10 columns. Keys resize to fit the screen so you can tap without scrolling. ■ Split screen — up to 12 calculators Split vertically and horizontally. Each pane keeps its own expression, result and memory. On tablets and foldables: up to 3×4 (12). On phones, only splits that keep keys easy to tap are allowed. ■ 65 buttons — 45 operators and functions Arithmetic, percentage (200 + 5% = 210), trigonometry (sin/cos/tan and more), logs (log/ln), power (^), factorial (!), permutations and combinations (nPr/nCr). Switch DEG and RAD instantly. Show only the keys you need. ■ 49 languages and 53 countries/regions Matches the languages offered on Google Play and the App Store. Country names appear in your language. Five digit-grouping styles (US, Germany, France, Switzerland, India lakh). Choose Eastern Arabic numerals (٠١٢٣٤٥٦٧٨٩) or Thai numerals (๐๑๒๓๔๕๖๗๘๙) where used—no kanji numeral conversion. RTL languages (Arabic, Urdu, Hebrew, Persian) are supported; number keys stay in 7 8 9 order. ■ Voice, sound and accessibility TTS reads each button press and the result (voice follows your selected region when available). Works with TalkBack and VoiceOver. Nineteen key-press sounds that do not stop your music. Menus follow system text size. ■ Six preset themes + custom colors Default follows your device light/dark setting (only Default follows the system). Also Dark, Colorful, Pastel, High Contrast and Minimal. Set button and text colors for number, operator, function and special keys (RGB plus 21 swatches). Hard-to-read combinations cannot be saved. When it shines • Work: quotes, currency and sales side by side • Study: compare approaches on one screen • Everyday: totals vs discounts, or split materials and time with remainder mode • Yours: rearrange keys and themes into a puzzle-style workspace Built by Cc Inc (https://inccc.jp/)
