AllSymbols Keypad

AllSymbols Keypad is a professional iOS keyboard extension for people who type symbols more often than emoji. System keyboards hide math, science, and tech symbols deep in pages; AllSymbols Keypad puts them one tap away in WeChat, Notes, Notion, Pages, Word, Excel, Safari, Mail, Obsidian, or any text field. One keyboard, nine domains. Science covers math, physics, chemistry, and biology. Earth & Space covers geology, astronomy, and meteorology. Engineering & Tech covers computer science, electronics, mechanics, and civil engineering. Medicine & Health covers clinical, pharmacology, anatomy, and more. Humanities & Social Science covers linguistics, philosophy, law, and history. Business & Finance covers currency, accounting, statistics, and economics. Arts & Design covers music, typography, and visual design. Specialized Fields covers chess, religion, sports, cooking, and library symbols. General Symbols covers arrows, brackets, bullets, punctuation, and dingbats. Flat, fast navigation. Instead of nested menus, subjects are laid out as a single swipeable tab bar at the top of the keyboard. Tap a direction tab to instantly see its symbols. From Science, tap Math, then choose Calculus for d, nabla, infinity, lim, sum, integral, contour integral. From Medicine, open Clinical and pick Vitals for degree-C, mmHg, micro-L, female, male, Rx, Delta. No hunting, no Wikipedia. Recent symbols, ready when you are. The star key toggles a recent list, so the symbols you use most float to the top automatically after first use. Long-press any key for a large preview before inserting. Optional key click sounds give satisfying feedback while you type. The keyboard works system-wide exactly like Apple's own extensions. Speaks your language. Subject and direction names are localized in more than 60 languages and automatically match your device language. English, Chinese, Japanese, Korean, French, German, Spanish, Portuguese, Russian, Arabic, and Hindi are supported out of the box. Keep it yours. Enable only the subjects you actually use. A linguist can skip circuits, a quant can skip phonetics, a calligrapher can skip diagnostics. Turning a subject off removes its tabs and keeps the bar clean and uncluttered. Real workflows. Draft physics homework in Notes without LaTeX. Reply in WeChat with correct units. Write H2O and alpha-decay notation in Notion. Prepare finance memos with mu, sigma, delta-NPV, and bitcoin. Annotate patient charts with mmHg, mg/dL, and degree-C. Build design decks with copyright, registered, trademark, and grid marks. Optimized for iPhone and iPad. Larger symbol grids on iPad, thumb-friendly spacing on iPhone, and automatic light and dark mode. Three keyboard heights let you dial in the perfect balance between symbol density and screen space. Privacy-first. AllSymbols Keypad is a standard iOS keyboard extension. It makes no network requests while you type, performs no keystroke logging, and never transmits your input. Symbol insertion is fully offline. Full Access is optional; you can type symbols without granting it. Typing is automatically suspended in password and phone-number fields for security. Setup in 20 seconds. Install the app, then go to Settings, General, Keyboard, Keyboards, Add New Keyboard, and select AllSymbols Keypad. Open any app, tap the Globe key, and switch to it. Pick your domains once, and type everywhere. Stop hunting for the sum symbol. Start typing like the paper is already written.
