Finding the symbol you want to use in LaTeX can be hard since you can't memorize all the commands and packages for every symbol. DeTeXt tries to solve this problem by giving you two ways to find the command you want: - Draw the symbol you want and DeTeXt's neural image classification engine will identify what it thinks are the 20 most likely LaTeX commands that will generate a symbol closest to the one you drew. DeTeXt supports Apple Pencil drawings on the iPad. - Search the entire symbol set of 1098 symbols from packages like tipa, amsmath, amssymb, textcomp and more, in addition to the default mathematical symbols. - Copy the symbol, or the character itself, or its Unicode codepoint to the system clipboard, to paste anywhere else. DeTeXt's neural engine processes your drawn symbol and finds the best matches in its symbol database, all on your device without requiring you to be online. All the symbols are stored within the app as well.

Verdict
The clearest difference is price: DeTeXt at Free against ChemiCalc's $0.99. DeTeXt also leads on update cadence (every 2 months vs every 38 months) and ratings volume (43 vs 2). ChemiCalc's advantage is iOS requirement (15.6 vs 26.0). On rating, review sentiment, ads and in-app purchases there is nothing between them.
