A minimal and beautiful app to quickly find and copy universal symbols and their HTML codes. --Symbol Library------- • ISO-8859-1 • Reserved Characters: &, ', "", etc. • ISO 8859-1 Symbols: ¡, §, ¼, etc. • ISO 8859-1 Characters: Æ, Ã, etc. • HTML Symbols • Math Symbols: ∑, ∫, ⊕, etc. • Greek Symbols: Ψ, θ, etc. • Other Entities: ‰, ™, œ, etc. • Special Symbols • ⌘, ↩, ⌥, etc. --Equation Editor------- An equation editor can be found on the top of the table view. You can copy multiple symbols and they are added to the editor in order. You can also edit the equation using a keyboard, which also lets you easily copy it! Thus, you can compose entire equations in 'Simbol' and then copy them for use in another app. This doesn't take away your ability to copy individual symbols. When you tap the 'Copy' buttons in detail views, you get that symbol on your clipboard, in addition to it being added to the equation editor. :)
