PhysicsBench: Circuit Puzzle
Optics, levers & science lab
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
108 physics levels in seven subjects. Three complete sample answers per subject. Pro includes all answers and advanced tools. One-time purchase, no subscription.
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
• 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.
