By allowing you to review your formulas as you type, it helps prevent typos and calculation errors. You can also reuse past formulas and utilize variable memory to recalculate by changing only specific values.\n\nThe on-screen cursor allows you to quickly navigate to where you want to edit by tapping or using the arrow keys. Featuring a powerful, flexible, and intuitive user interface, the app also supports swiping to scroll through formulas and long-pressing to copy and paste.\n\n[Features]\n- Recalculate easily using past formulas\n- Effortless editing with cursor navigation and screen swiping\n- Copy and paste formula text\n- History log for both formulas and calculation results\n- Binary, octal, decimal, and hexadecimal calculation and conversion (Up to 32-bit)\n- M+/M- memory functions and variable memory (A–F)\n- Support for arithmetic operations, inverse trigonometric functions, logarithmic functions, power/root functions, factorials, absolute values, percentage calculations, modulo operations, and polar/cartesian coordinate conversion\n- Multiple angle units (DEG, RAD, GRAD)\n-Multiple display formats: Normal (standard), Fix (fixed decimal), Sci (significant figures), and Eng (engineering notation in multiples of 3)\n-Customizable decimal point characters and grouping separators\n\n[Disclaimer]\nPlease note that Appsys accepts no responsibility for any damages, lost profits, or claims from third parties arising from the use of this software.","facts":{"developer_id":668500806,"developer_url":"https://appsys.jp","first_released":"2013-07-09T23:44:19Z","support_url":"https://appsys.jp/","privacy_url":"https://appsys.jp/cms/en/privacy-policy","website_url":"https://appsys.jp/","app_version":"7.7.3","release_notes":"- Minor bug fixes and improvements.","rating_current_version":4.77969,"rating_count_current_version":1979,"star_counts":[41,17,46,129,1746],"genres":["Utilities","Business"],"languages":["EN","FR","DE","ID","IT","JA","PT","RU","ZH","ES","ZH"],"content_advisories":null,"device_families":["iphone","ipad","ipod"],"chart":null},"freshness":{"apple_read_at":"2026-10-21T18:08:13.146Z","catalog_read_at":"2026-10-20T00:54:11.538Z","reviews_checked_at":null,"summary_written_at":"2026-10-20T20:28:14.296Z","placed_at":"2026-10-20T20:19:13.712Z","scored_at":"2026-10-21T20:52:12.727Z"},"editorial":{"one_liner":"Scientific calculator that displays and edits formulas as you type, with formula reuse, variable memory, and multi-base.","what_is":"Panecal is a scientific calculator app that shows formulas for review and editing while you type.
