About this app

No account. Works offline. Solve any formula for any variable. Physics formulas, a physics calculator, physics equations and a physics formula sheet in one free physics solver.

EVERY FORMULA IS A SOLVER
Open any of 257 physics formulas, tap the quantity you need and enter the ones you know. Each value can use its own unit: km/h, mph, minutes, kilojoules, degrees Fahrenheit and more. The physics calculator converts everything to SI, solves with a pre-derived rearrangement and shows the rearranged equation plus every conversion step, so you can follow the working instead of copying a number.

Inputs are checked before solving. A mass must be positive, a square root needs a non-negative value and a missing input is named. You get a clear message instead of a wrong answer.

12 TOPICS, HIGH SCHOOL TO FIRST-YEAR COLLEGE
• Kinematics and forces
• Energy, work and momentum
• Circular motion, gravity and rotation
• Fluids and thermodynamics
• Waves, sound and optics
• Electricity, circuits and magnetism
• Modern physics

Search physics equations by name, symbol or keyword, and star the ones you use most. Each formula has a short explanation, its variables with SI units, any conditions it needs and a worked example.

A FORMULA SHEET IN YOUR POCKET
The constants table lists the speed of light, the Planck constant, the elementary charge, the Avogadro and Boltzmann constants, the gravitational constant, standard gravity and more, with exact SI values marked. A unit converter covers the same units the solver uses. Choose significant figures and degrees or radians in Settings.

PRACTISE UNTIL IT STICKS
Three quiz modes: recognise the right equation, pick the SI unit of a quantity, or solve a quick numerical problem built from the formulas. Your progress is saved on your device.

FREE AND OPTIONAL PRO
All formulas, the solver, the constants table and the unit converter are free. The first three quiz topics are free. Pro unlocks every quiz topic, PDF topic sheets and removes ads, with monthly, yearly and lifetime choices at Google Play prices. A rewarded ad can unlock one more quiz topic for 24 hours.

Educational tool; check results against your course materials. Formulas, constants and examples are bundled in the app; nothing is generated at runtime. Ads and purchases need a connection.
