This app is fake/terrible
This app is nothing more than a copied periodic table with pop up incorrect information atomic masses on most transitiin metals are incorrect, the text in it is very sparce and incomplete, looks copied/pasted from some college level cheat sheet. Very very little material 5 pages max. Nothing having to do with chemical formula, precursors or anything. To put thr final nail in the coffin the ui is horrible, it allows you to type in text and edit the periodic table or add and write new topics, looks like someone was trying to scam a few bucks. Do-not purchase this application.
