2000 Words vs Physics Zen

2000 Words teaches the vocabulary that actually carries a conversation — the 2000 most frequent words in German, Spanish, Italian, French, Bulgarian and Russian, all in one app. Every language is paired with English. So it is for English speakers learning one of the six — and for speakers of those six learning English, with the direction switched round. The first 100 words of every language are free. No time limit, no account, no advertising. Unlock a language for its full 2000 words when you want it, or take all six at once. Why 2000 words? That range covers the large majority of everyday speech. Learn it and you follow real conversations, messages and films far sooner than by grinding through endless lists. Across six languages that is more than 12,000 words. In every language: • Levels that build on each other: Top 100, Top 500, Top 1000, Top 2000 and rare words • Native pronunciation on every word — tap to hear it • Example sentences that show the word in use • Plurals, verb forms and other details where they matter • German and Spanish add an article drill: der/die/das, el/la/los/las • Flashcards that keep track of what you already know • Autolearn: hands-free playback for commutes and walks • An Apple Watch app for practice away from your phone New in 2000 Words: Read. • Classic books in the language you are learning, with English a tap away — paragraph by paragraph • Add your own EPUB or text files, or photograph the pages of a printed book and read it on screen • Tap a word to see what it means and save it; saved words come back for review, spaced out as you learn them • Read a paragraph aloud and see which words you got right • Chapter checks, and the whole chapter read aloud to you if you like Reading is free for 20 minutes every day. A one-time unlock removes the limit, and it is included if you bought all six languages. Translating your own books and single words happens on your device and needs iOS 18. Switch target language whenever you like — progress in each is kept separately, so picking Spanish back up after a month in German loses nothing. The app itself speaks your language too — English, German, Spanish, French, Italian, Bulgarian or Russian — and that is a separate choice from the language you are learning. Everything runs offline. There is no account to create, and your progress stays on your device and in your own iCloud. If you bought 2000 Words before it became free, all six languages stay unlocked for you. There is nothing to restore and nothing to do.

Physics Zen turns physics into focused, repeatable practice. Work through fresh generated problems, check your answer instantly, and open the theory or worked solution exactly when you need it. A COMPLETE PHYSICS PATH Practice 66 skills across 21 topics: • Mechanics: motion, projectiles, forces and friction, energy, momentum, centre of mass, rotation, circular motion, gravitation, oscillations and fluids • Electricity and Magnetism: electric fields, circuits, capacitors, RC transients, magnetic fields, induction, inductance and AC • Waves and Optics: wave graphs, sound, interference, reflection, refraction, lenses and diffraction • Thermodynamics: heat, gas laws, kinetic theory, entropy, engines and renewable energy • Modern Physics: photons, matter waves, X-rays, nuclear physics, particle physics and special relativity EXAM PREP Twelve exam paths, each built from the topics its exam actually tests: • AP Physics 1, AP Physics 2 and AP Physics C: Mechanics, with free-response items that give follow-through marks • A-Level Physics, with required-practical data analysis: tables, gradients and uncertainties • HKDSE Physics (Hong Kong) • Abitur Physik, with fine-beam tube and Wien filter labs • French Bac physics, including Newton's law of cooling and the telescope; chemistry and the practical assessment are not included • Japan's University Entrance Common Test in Physics and Basic Physics, with digit-cell answers • Korea's CSAT (Suneung) Physics I, and the physics part of CSAT Integrated Science from 2028 • Taiwan's Advanced Subjects Test (分科測驗) Physics, which also covers the physics in the GSAT (學測) science paper • Board-specific gravity conventions Every item is original practice, not an official exam paper. BUILT FOR PRACTICE Generated Problems: Practise fresh parameter combinations across multiple difficulty levels. Mastery Progression: A five-level bucket system moves from foundations to multi-step problems as you demonstrate understanding. Theory Beside the Problem: Open concise explanations, formulas and worked examples without leaving your session. Mistake Journal: Wrong answers are saved automatically. Retry the same concept later with fresh numbers. Visual Physics: Graphs, force diagrams, circuits, waves, rays, energy levels and fluid scenes support the problems that need them. Offline First: The curriculum and generator work without an internet connection. Optional sign-in adds cross-device sync. Focused Interface: No ads, no coins and no lives. Includes light and dark themes. Content is available in twelve languages: English, German, French, Spanish, Brazilian Portuguese, Dutch, Swedish, Japanese, Simplified Chinese, Traditional Chinese, Korean and Russian. HOW IT WORKS 1. Choose a section, topic or exam path. 2. Solve a generated problem at your current level. 3. Check your answer and read the worked solution. 4. Build mastery and return to mistakes that need another pass. Most skills are free, and Kinematics is free end to end. Premium unlocks the last skill of each topic, the exam-prep paths and detailed statistics. Subscription and lifetime options are shown in the app with local pricing before purchase. Subscriptions renew automatically unless cancelled at least 24 hours before the end of the current period. Manage or cancel them in your App Store account settings.
