Set Theory Fundamentals vs Newtonic

Set Theory Fundamentals is an independent study app for building confidence with core set theory ideas through focused practice. It is designed for students, self-learners, and anyone reviewing mathematical foundations for coursework, interviews, or exams. Practice across four topic areas: Fundamentals, Practical Skills, Common Pitfalls, and Advanced Concepts. Work through 160 questions covering notation, operations, relations, functions, proofs, cardinality, and common reasoning traps. Features: - FSRS spaced-repetition intervals to help you review at the right time - Weak-point heatmap to spot topics that need attention - Daily challenge for consistent practice - Mock exams for timed review - Explanation included with every question - Offline practice, no login required Practice offline, no login required. Your study flow is built for private, repeatable review. Independent study app for Set Theory Fundamentals practice.

Newtonic turns 59 physics topics into simulations you can push around. Throw a ball and watch the range change with the angle. Swing a double pendulum into chaos. Bend light around a galaxy. Fire an electron at a barrier and watch part of it tunnel through. Every topic comes in several ways: • Simulate: change real quantities, in real units, and watch the system answer. Every readout is computed from the actual equations. • Learn: the formulas with every symbol explained, a short plain-language explanation, the key ideas and guided experiments to try. • Quiz: a few questions with explanations, so you know what you understood before the exam does. • Practice: exam-style problems with new numbers every time, on 12 topics. Get a hint, reveal the solution step by step, then load the problem into the simulation and watch your answer happen. Lab tools sit right on the stage: measure with a ruler in real units, time a run with a stopwatch on simulation time, and keep a ghost of one run to compare with the next. Tap Solve under a formula to find any quantity from the others, starting from the values on your sliders. Follow a course for your exam, YKS, AP Physics 1 and 2, A-level, or Abitur, Bac and Maturità, unit by unit, with your progress on every step. Share a setup: send a picture of your simulation with its values, and a link that opens it in Newtonic exactly as you left it. Earn XP as you explore, read, take quizzes and solve problems, keep a daily streak and collect 22 badges along the way. Today's practice puts three fresh problems on Home every day. Tell Newtonic your level and favorite fields, and Home suggests what to try next. Your progress syncs across your iPhone and iPad through iCloud, a widget keeps your streak on the Home Screen, and an optional reminder nudges you on days you haven't studied yet. 59 simulations across 11 fields: classical mechanics, gravity and orbits, fluids, oscillations, waves and sound, thermodynamics, electricity and magnetism, optics and light, relativity, quantum mechanics, and atomic and nuclear physics. Made for high school and university students, whether you're studying for an exam or meeting physics for the first time. Works offline. No account, no ads, no tracking. On iPad, the controls sit beside the simulation and a sidebar keeps every section one tap away. Free and Pro 18 simulations are free forever, at least one in every field, with their practice problems. Newtonic Pro unlocks all of them and every practice problem, plus every new simulation as it arrives: • Yearly, with a one-week free trial • Monthly • Lifetime, a single purchase Payment is charged to your Apple Account when you confirm the purchase. Subscriptions renew automatically unless canceled at least 24 hours before the end of the current period, and your account is charged for the renewal within the 24 hours before the period ends.
