Reagent: Chemistry Quiz

Reagent is chemistry revision that explains itself. When you miss a question, you decide how deep the explanation goes, and the deepest setting shows the tutor's own worked steps rather than a paragraph invented afterwards. The answer key is hand-written and hand-checked, and the tutor is never allowed to contradict it. What changes is how much of the reasoning you get to see. - Six concepts to drill: acids and bases, redox, kinetics, stoichiometry, organic chemistry and periodicity - Twenty-four hand-written questions, four per concept, each with its own explanation - Get one wrong and pick your depth: a hint, a fuller explanation, or numbered worked steps - Balance five real equations with steppers and a live atom tally that marks each element as it evens out - Ask why on a wrong balance and the same explanation ladder opens up - Spaced review that brings a concept back the day you are about to forget it - A tutor profile you can read and override, showing what it thinks you know On a device without Apple Intelligence the explanations come from the hand-written bank at a single depth, and every question still works. It all runs offline, with no account.
