MathOS User Manual
A quick guide to every feature. Tap a section to expand it.
The Dashboard is your home screen — tap any card to open that section full-screen.
- Use the ‹ Back button (top-left of any page) to return to the Dashboard.
- The ☀️/🌙 button (top-right) switches between Day and Night mode.
- The Install App button adds MathOS to your home screen for faster, full-screen, offline access.
- The ½ / .5 pill switches how answers are displayed — as fractions or decimals.
Planning opens the Curriculum Engine, covering CBC Kenya grades 4–6. It has its own tab bar:
- Browser — explore subjects and topics by grade.
- Search — find any topic across all grades instantly.
- Schemes — prepare schemes of work for a term.
- Lessons — create and organize individual lesson plans.
- Records — keep track of what's actually been covered in each lesson.
- Coverage — see your progress through the curriculum at a glance.
All curriculum data is loaded on first use and then cached for fully offline access afterward.
Build and manage reusable exam questions here.
- Create Question Templates, organized by topic, difficulty, and section.
- Use the Assessment Paper Generator to automatically assemble a full CBC-style exam paper — Section A & B, an answer key, and a marking scheme — from your saved templates.
Once you've marked an exam, this is where results are processed.
- Enter marks and automatically generate Merit Lists and class rankings.
- Apply CBC grading to score entries.
- Export finished reports as PDF or Excel.
Ask the AI Tutor to solve word problems, algebra, money and finance questions, or almost anything else — with a full step-by-step explanation, not just the answer.
Requires an internet connection — unlike the rest of MathOS, this feature can't work offline.
Six focused calculators and reference tools, fully offline:
- Numbers — fractions, indices, ratios, sequences.
- Geometry — shapes, trigonometry, Pythagoras, graphing.
- Data — statistics, probability, speed calculations.
- Finance — tax, VAT, hire purchase, interest.
- Algebra — linear equations and matrices.
- Scientific — a full scientific calculator, also reachable directly from the Math Modules card.
MathOS uses a one-time activation, not a recurring subscription.
- New installs start with a 5-hour free trial so you can try every feature.
- The banner at the top of the Dashboard always shows your real, live status — trial time remaining, or your activation once purchased.
- Already have a license? Use Restore Existing License or Enter Activation Key from the activation screen, or from Settings.
Find your license status, app version, and developer contact details here.
- MathOS is offline-first — everything except the AI Tutor works with no internet connection at all.
- Your templates, papers, records, and marks are stored locally on this device.
- Backup & Restore and full data export/import tools are planned for a future update.
