KEY FEATURES

• Personal AI Tutor — Greets you by name, knows the 0620 syllabus, and writes every reply in mark-scheme phrasing. Snap a photo of an apparatus diagram for a step-by-step worked answer.

• Mark-Scheme AI Marking — Got a question wrong? Tap "Explain with tutor" — the tutor opens with the question, your answer, and the correct answer pre-loaded, and walks you through what mark schemes reward. Zero typing.

• Command Words Trainer — Cambridge IGCSE mark schemes treat words like "describe", "explain", "suggest", "compare" as load-bearing. The trainer covers all eight high-frequency Cambridge command words with examiner notes, and lets you practise each one against a real AI-generated question, marked examiner-style.

• Real Past-Paper MCQs — 1,133 actual Cambridge IGCSE Chemistry MCQs from 2018-2024. Mark-scheme answer revealed after every guess, with a Bjork-style confidence probe between answer and reveal that calibrates your metacognition.

• Mistake Journal — Every wrong answer collects in a searchable journal with the right reasoning beside it. Filter to "Recalibrate" (felt sure but got it wrong — your highest-leverage study time) or "This week" for daily triage. One-tap "Explain with tutor" on every entry.

• Concept Flashcards — 50+ mark-scheme-style cards across the full 0620 syllabus. Chemistry terms (covalent bond, mole, amphoteric oxide), named processes (electrolysis, blast furnace), and key equations (n = m/Mr, percentage yield, Rf).

• Mock Exam Mode — Run a timed paper that mirrors the real exam format. Detailed breakdown of what you missed and where to focus next.

• Multilingual Glossary — 40+ key science terms with translations into Urdu, Hindi, Tamil, Arabic, Bahasa Malay, and Mandarin alongside the English. Built for non-native English IGCSE candidates across South Asia, the Middle East, and Malaysia. Always shows English first — you still need to write English in the exam.

• Progress Dashboard — Daily ring, weekly accuracy, topic mastery, streaks, exam countdown. Calibration callouts surface what you felt sure about but got wrong.

• Coach Mode — Flip the tutor into Socratic mode. Instead of handing you the answer, it nudges with hints so you reason it out yourself.

• Sleep-Positive Reminders — Late-evening reminders are silenced past 10pm so they don't compete with sleep. Streak unaffected.

• Topics — Browse the full 0620 syllabus across 14 areas (atoms and bonding, stoichiometry, electrochemistry, acids and salts, organic chemistry, ions and gases, and more), plus an "Exam Skills" section with Command Words and Glossary.

• Native iOS + iPad — Dark mode, Dynamic Type, haptics, VoiceOver. iPad sidebar with conversations and a full-width chat in the detail pane.

BUILT FOR CAMBRIDGE IGCSE

Every question, flashcard, topic, and worked answer is tuned to the Cambridge 0620 syllabus. The tutor knows the command words ("describe", "explain", "compare", "predict") your examiner expects and writes answers in that style.
