Ionika

Ionika is the essential learning app for students of chemistry, pharmacy, and related natural sciences in the analytical chemistry module. Instead of passively clicking on predefined answers, you construct real reaction equations using ion, molecule, and stoichiometry chips—exactly as required in the exam.

The database is streamlined and free of unnecessary clutter: all the core evidence for cation and anion separation pathways is included and explicitly curated for maximum exam relevance. Learn more efficiently, track your progress, and approach the exam with confidence.

Completely ad-free, no subscriptions, no tracking, and 100% usable offline.

KEY FEATURES & HIGHLIGHTS

Interactive drag-and-drop equations: Real understanding through active assembly instead of simple multiple choice.

All relevant separation processes: HCl, H₂S, (NH₄)₂S, (NH₄)₂CO₃, soluble group, and anions (halides, oxyacids of the halogens, sulfur anions, etc.).

6 focused learning modes: Choose between free learning session, study list, review of mastered reactions, targeted error review, or browse the reaction catalog.

Exam simulation: Test your knowledge under realistic conditions with a timer and detailed evaluation (comprehensive or separated by cations/anions).

Scientifically sound: The integrated spaced repetition system clearly displays the "due today" counter for optimal memorization.

Dynamic daily learning goal: Enter your exam date, and the countdown automatically calculates your optimal workload for the day.

DESIGN & DATA PROTECTION

Dark mode for eye-friendly learning.
