Every step of the physics answer.

Pick what you need to find, type the values you already have in the units you have, and Newtora shows the formula, how it is rearranged, the switch to SI units, the numbers plugged in and the answer.

Newtora solves the problems you type in. It does not scan photos of homework and it does not use AI — every answer comes from the formula shown on screen.

Newtora is a physics problem solver for Android. You choose a topic, tap the variable you want to find and enter the known values in any unit; the app rearranges the formula, converts every value to SI units, substitutes the numbers and shows the answer in the unit you choose. It covers 48 topics from kinematics and Newton's laws to thermodynamics, optics, circuits and modern physics, with a unit converter, a constants table and a saved history of every solution.

Pick the unknown

Every topic lists its variables. Tap the one you need — time, force, current — and the formula is rearranged for it.

Any unit in, the right unit out

Type km/h, mph, °F, atm, kΩ or eV. Each value is converted to SI units in a visible step, and the answer can be shown in the unit you want.

Every step on screen

Formula, rearranged equation, SI conversion, substitution and answer — the same order a teacher writes on the board.

Signs and powers of ten done right

Negative accelerations and values like 1.6 × 10⁻¹⁹ C are handled and shown clearly.

48 topics

Motion, forces, energy, fluids, heat and gases, waves and optics, electricity and modern physics.

Unit converter and constants

Convert length, speed, pressure, energy, temperature and more. Copy g, G, c, h, e, k or R with one tap.

History and favorites

Every solution is saved. Open it again before a test, or star the topics you use most.

Formula of the day widget

A home screen widget shows one formula a day. Tap it to solve with it.

FAQ

Is everything really unlocked?
Yes. All 48 topics, the converter, constants, history and widget are included. There is no Pro version. The app is supported by ads, which never appear on the screen where you type values.
Can I enter values in km/h or °F?
Yes. Every value has a unit picker. The app converts to SI units and shows that conversion as its own step.
Does it show how the formula is rearranged?
Yes. When the unknown is not the subject of the formula, a step shows the rearranged equation before the numbers are substituted.
Can it solve a problem from a photo?
No. Newtora works from the values you type in. It does not scan images or use AI.
What level of physics does it cover?
High school, AP Physics 1 and 2, and first-year college physics: kinematics, dynamics, energy, fluids, thermodynamics, waves, optics, electricity and an introduction to modern physics.
Does it work without internet?
Yes. All topics and calculations run on your phone. Your solutions stay on your phone too.
