Physics Quest
Ages 8–12 · iPhone & iPad

Physics you can play.

Eight hands-on labs where kids stack towers, fire cannons on the Moon, sort magnets and wire circuits. Every level ends by explaining why it worked.

Real experiments, real numbers

The labs run on true physics. A shot that lands short says by how many meters. A floating block sits exactly as deep as its density says it should.

Planet Hop: a cannon shot lands 6 meters short of the basket, with a dotted trail and air-time readout.

Planet Hop · “Landed at 24.0 m, 6.0 m short”

Circuit Builder: wires glow yellow and the bulb lights up once the loop is closed.

Eight labs, four levels each

Each lab opens with a “Big Idea” card, builds up across four missions and ends with a short Brain Check quiz.

LAB 01

Tower Tumble

Center of mass & balance

Stack swinging shapes on a table and keep the yellow balance dot over the base.

LAB 02

Wind Blaster

Mass, momentum & forces

Slingshot light, medium and heavy balls through tailwinds and storms.

p = m × v
LAB 03

Planet Hop

Gravity & projectiles

Land the same cannon shot on Earth, the Moon, Mars and Jupiter.

g = 9.8 · 1.6 · 3.7 · 24.8 m/s²
LAB 04

Slide Stopper

Friction & energy

Choose the floor and ramp height that parks the sled in the zone.

d = v² ÷ 2μg
LAB 05

Magnet Mania

Magnets & poles

Grab only the magnetic junk, then flip train cars so every N meets an S.

N + S attract
LAB 06

Swing Lab

Pendulums & energy

Tune a pendulum to a drum beat, ring a glass bell gently, build a Moon clock.

T = 2π√(L ÷ g)
LAB 07

Float or Sink

Density & buoyancy

Predict, then watch how deep things float. Load a cargo boat to its limit.

LAB 08

Circuit Builder

Electricity & circuits

Turn wire tiles to close the loop. Only metals let the current through.

no gap = light

Built for kids, safe for families

  • No ads, no in-app purchases and no accounts.
  • Collects no personal data and never connects to the internet.
  • Progress is saved only on the device.
  • Settings sit in a Grown-ups area behind a parental gate.
  • Sound effects and vibration can each be switched off.

Made to teach, not just entertain

  • Levels are calculated from real formulas and real planetary gravity, so every level can be solved.
  • Wrong tries give a hint about the physics, not just “try again”.
  • A “Why it worked” card after every win names the idea in plain words.
  • Stars, XP ranks and badges reward accuracy, not time spent.
  • Fits classroom topics on forces, energy, magnetism, density and electricity.

Support

Questions, bug reports or ideas for new labs: email support@gript.io. We usually reply within a few days.

Which devices does Physics Quest run on?

iPhone and iPad with iOS or iPadOS 17 or later. The game plays in landscape.

Does it need an internet connection?

No. Everything runs on the device, so it works on planes, in cars and in classrooms without Wi-Fi.

How do I reset my child's progress?

On the home screen, tap Grown-ups (bottom left), answer the question, then choose Reset all progress. Deleting the app also removes all progress.

How do I turn off sounds or vibration?

Open Grown-ups and switch off Sound effects or Vibration. Sounds also follow the device's silent switch.

Is progress shared between devices?

No. Progress stays on the device it was earned on. Physics Quest does not use iCloud or any other online service.
