We help solve your homework problems, draw the answers and show you step by step how to get the answers. For Trig based Physics classes. Do you need help doing your homework problems? Are you having trouble just getting started? Are you tired of trying to follow along with the 'how to' videos online? Why can't you just put the problem into the app and get the answer? We can. Included in this version: - Quick Start Guide - Vector Calculator - Vector Resultant Calculator - 1-D Kinematics Calculator - 2-D Kinematics Calculator - Newton’s Laws Calculator - Momentum Calculator - Impulse Calculator - In-Elastic Collision Calculator - Elastic Collision Calculator - Torque Calculator - Net Torque Calculator With Applications on - Free Body Diagrams - Object on a Flat Plane - Object on an Incline Plane - Object against Vertical Wall - Tension on Object from 1 Cable - Tension on Object from 2 Cables - Momentum - Impulse - In Elastic Collisions - Conservation of Momentum - Elastic Collisions - Conservation of Kinetic Energy and Momentum - Object in Free Fall - Projectile Shot straight up - Projectile in Motion at an angle - Torque - Net Torque (Beam) - Net Torque (Compound Wheel) And we show you how we did it. Additionally, if your teacher throws you a curve ball, we also provide you the ability to model a fixed scenario of your choosing in the iPad version. While iterating the scenario you can change specific variables-including incline angle, force applied, force applied angle, mass, and coefficient of static friction. Modeling functions generate step by step reports for each answer so you can check your work. Free Trial is not by time but rather by usage. Specifically, each time you model a scenario, or run a simulation, or solve a Kinematic equation you will use one of 2 free attempts. After you have completed the free trial you can can access the app with one of the subscription options below. Some modules use more than one use to solve the final problem including Impulse and Collisions. Options: Users can at his/her option choose the following passes. 1) Semester Pass - 5 months of full access.

Verdict
The clearest difference is rating: Photronium at 5.0 against Physics Homework's 3.9. Photronium also leads on review sentiment (100% vs 67%). Physics Homework's advantage is update cadence (every 3 days vs monthly). On price, ratings volume, ads and in-app purchases there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Physics Homework sells 9 one-off in-app purchases and Photronium sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
Photronium holds the better App Store score, 5.0 against 3.9. Both are backed by a comparable volume of ratings — 18 and 10 respectively. Written reviews point the same way: 67% of Physics Homework's written reviews are positive against 100% of Photronium's.
Physics Homework ships an update every 3 days, Photronium monthly. The most recent releases landed on October 21, 2026 and October 23, 2026 respectively.
