Overview

A skill-first IB Chemistry study app

ChemIBex helps students build durable problem-solving habits instead of relying on one-off answer hunting. The app is designed around how chemistry understanding grows: explanation first, focused practice second, and deeper mixed-idea application third.

Features

Three connected learning pillars

Macro-Skills

Build the broad reasoning patterns that repeat across IB Chemistry, including stoichiometric setup, graph interpretation, structural thinking, and rate/equilibrium logic.

Micro-Skills

Study unit by unit with focused chemistry skills, concise concept explanations, exam tips, imported visuals, and practice collected in one place for each skill.

Case Study

Work through advanced crossover problems that connect multiple units and reveal how strong chemistry answers are structured step by step.
