About this app
Master STEM, one lesson at a time. Faraday is a focused, offline, game-style learning app — not another wall of PDFs — whether you're prepping for an exam or learning a subject for its own sake.
Pick from 64 courses across maths, science, engineering and computing, and work through bite-size lessons, each with a short teaching segment and practice questions with full worked solutions. Build a daily habit with streaks, XP, hearts, achievements, and a gem store.
Courses span Calculus and Algebra, Physics and Chemistry, Biology and Psychology, Machine Learning and Cybersecurity, Economics and Personal Finance, Astronomy and Rocketry — alongside AP, SAT and GRE preparation and full PE Power and FE Electrical & Computer licensure prep with timed, per-area mock exams. Switch between courses anytime.
Everything runs completely offline — no account required, no internet needed after install, and your progress stays on your device.
WHAT YOU GET
• 13,000+ practice questions across 64 courses and 522 knowledge areas
• Short, focused lessons with step-by-step solutions (formulas rendered properly)
• Full-length, timed mock exams with per-area score breakdowns (engineering courses)
• Smart review: missed questions come back on a spaced schedule
• Stay motivated: streaks, streak freezes, daily goals, XP, achievements, and gems
• Track progress per knowledge area
• 100% offline and private — no account, no ads, no tracking
• One-time purchase — start free, then unlock everything. No subscription.
