班主任清单 vs PhysicsBench

A class management tool designed for primary and secondary school homeroom teachers and university counselors. Whether you are a new homeroom teacher just taking over a class, or an experienced educator looking to improve daily management efficiency, Homeroom Checklist helps you centrally manage student information, daily records, and to‑do items, bringing order to the complex work of class management. Key Features: • Class Management Create, switch, and manage multiple classes, with clear recording of grade, academic year, and other details. • Student Profiles Record student names, student IDs, gender, contact information, and notes, with support for batch adding students. • Daily Records Quickly log leave requests, disciplinary issues, commendations, parent‑teacher communication, to‑dos, and other matters. • Follow‑up Reminders Record follow‑up dates and centrally view student matters that require further attention. • Growth Records View historical records by student, helping homeroom teachers continuously track students’ in‑school progress. • Data Statistics Summarize recent class dynamics and various records, putting important information at a glance. • iCloud Sync Data can be synced via personal iCloud across devices signed in to the same Apple account. • Privacy Focused Student and class data are stored locally and in the user’s personal iCloud, and are not used for advertising or tracking. Homeroom Checklist aims to reduce repetitive organizing and paper‑based searching, making every record traceable and class management easier and more efficient. We welcome your feedback and suggestions.

Solve real physics, not fake wiring puzzles. PhysicsBench simulates actual circuits, light paths and torque — then shows you the formula behind your solution. Wire a battery, close a switch, watch current flow and a bulb light up. Bounce a beam off mirrors into the target. Balance a lever with the right weights. Every level ends with a Principle Card: the law, the formula, and your level's real numbers substituted in. MAIN FEATURES • 108 levels across seven subjects: Circuits, Optics, Mechanics, Dynamics, Electromagnetism, Heat & Fluids, Waves & Sound • Three difficulties per subject: Intro, Core, Brainer • True simulation — nodal analysis for DC circuits with diodes and capacitors, ray tracing for light, torque balance, and closed-form models for motion, induction, heat and sound • Principle Card after every solve, with your own values • Daily experiment with streaks • Courses by topic, a review queue for levels you needed hints on, and a mastery radar • Unlimited hints, never a consumable • Import and play levels friends share as a code or .physlab file • AR experiment bench: pendulum, ramp, projectile, collision and buoyancy run in 3D with the engine's real numbers; rotate, zoom, tune them and place them on your desk in AR • Open supported dynamics results in 3D with the level’s settings. Capture a frame and share an experiment card. Pro unlocks spoken derivations and tuning and AR for the four new scenes. • Home-screen widget, Apple Pencil notes and bench recording • Works fully offline. No ads, no accounts, no tracking PRO — ONE-TIME PURCHASE • All 108 levels, including every Brainer level • Full step-by-step derivation on every Principle Card • Frame-by-frame replay with velocity and force arrows, and a draggable RC charging curve • Free Bench lab: sliders for every model, plus building, naming and saving experiments • Level editor that proves your puzzle is solvable before you share it • Full probe panel: per-branch voltage, current and power; every beam path; torque breakdown • Four extra themes and three alternate app icons • Future local Pro levels in this app ANSWER REPORTS — OPTIONAL Pro includes every answer and all Pro features. One-time purchase. No subscription. Three sample answers per category are free to view again. Unlock Pro for all remaining answers. Existing answer-pack purchases can still be restored for their original difficulty. PRIVACY Everything runs on your device. Progress syncs through your own private iCloud. No account, no analytics SDK, no data sent to us. NOTE Levels use teaching-simplified models (ideal wires, batteries with internal resistance, single-colour rays). The in-app "About the model" page lists every assumption. Support · Privacy Policy · Terms of Use are in Settings.
