SciMath is a keyboard for iOS and iPadOS that gives you the symbols science, mathematics, and technical writing actually need - without copying from character maps, switching apps, or settling for approximations. Every symbol is a proper Unicode character. It copies, searches, and renders correctly in every app that supports Unicode text. ONE-TIME PURCHASE. No subscription. No in-app purchases. No advertising. Ever. FOUR LAYERS ABC - Full QWERTY with extended diacriticals on long-press. French, German, Scandinavian, Spanish, Eastern European, and scholarly Latin variants. 123 - Numbers and punctuation. Long-press any digit for its superscript and subscript form. #+= - Brackets, operators, and currency symbols. sci - Scientific and mathematical symbols: Operators: degree, plus-minus, multiply, divide, approximately, not-equal, less-or-equal, greater-or-equal, square root, infinity Calculus: summation, integral, partial derivative, nabla, delta, h-bar, Angstrom, micro, ohm Logic and sets: pi, therefore, for-all, proportional, element-of, prime, perpendicular, and more Long-press sci keys for additional symbols: element-of opens not-element, subset, superset, union, intersection, empty set, and more. FOOTNOTE SYMBOLS The complete traditional footnote sequence for mathematical and legal writing, where superscript numbers would be confused with exponents or indices. KEY FLASH Toggle key flash in the SciMath app. When on, keys brighten immediately on contact with no delay, visible in direct sunlight. When off, standard iOS balloon previews appear.
