Physics++ is the perfect companion for physics students and students of other science classes. Physics++ is a collection of physics formulas. The more than 120 formulas cover the topics mechanics, relativity, fluid mechanics, thermodynamics and electrodynamics. In addition there is a small number of primitives and a section with often used units. Physics constants are also included. With the search function formulas can now be found even faster. Most formulas have a calculator attached to them. So you can easily calculate values in exercises. In future update the number of formulas and constants will be increased.

Verdict
The clearest difference is price: Photronium at Free against Physics++'s $0.99. Photronium also leads on rating (5.0 vs 3.9) and review sentiment (100% vs 68%). Physics++'s advantage is in-app purchases (none vs 1) and iOS requirement (14.5 vs 16.4). On ratings volume, update cadence, ads and device support there is nothing between them.
