Math Dash vs PhysicsBench

Math Dash is a running game for times tables, math facts and spelling, made for ages 6 to 8. Pick Pip the pencil-tail fox, Tally the counting bot, Smudge the eraser bunny or Rumble the race-bib dino, then run, jump and grab the number bubble that answers the sum. Every right answer powers your hero up, and a wrong one is just a quick wobble. Pick Pip the pencil-tail fox, Tally the counting bot, Smudge the eraser bunny or Rumble the race-bib dino. Dress your hero up in costumes, then run, jump and grab the number bubble that answers the sum. Every right answer powers your hero up, and a wrong one is just a quick wobble. Run, jump, learn Math Dash is a fast, friendly running game that makes math practice feel like play. Pick the exact number to practice (like only +3 or x4) in Add, Subtract, Multiply and Divide, or try Fractions, Counting, Spelling and Patterns (logic). There is a Collect mode too. Tricky Facts Mixed up 7 x 8? Math Dash saves the facts your child gets wrong and turns them into a gentle practice run where the answer is hidden, so they really work it out. Get a fact right twice and it is mastered. Keep the fun going - A fresh daily challenge with bonus XP - Streaks, levels, stars and badges - Easy, Medium and Hard, and eight worlds to run through: Sketchbook, Meadow, Beach, Space, Forest, Arctic, Volcano and Underwater - Big, easy-to-read numbers made for small hands - A hand-drawn notebook look, and a chalkboard in dark mode - Siri shortcuts: "Practice tricky facts in Math Dash" or "Play today's challenge" - Available in 9+ languages For grown-ups Made for ages 6 to 8. The Grown-ups corner sits behind a parent check and holds sound settings, a haptics toggle and a progress report, so you can see how your child is doing. There are no ads, no tracking, no accounts and no chat. Progress stays on the device. Download Math Dash and let your hero dash for the answer!

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 Stuck? Unlock the worked answer for a difficulty with a separate one-time purchase: the solved bench, every move with its reason and the principle worked through. Not included in Pro; hints stay free. 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.
