A free program for Android, by NSC Co..
In this app, there are seven categories, which are mechanics, electricity, thermal physics, periodic motion, optics, atomic physics, and constants. The app also provides tools to help the user calculate some popular physics problems. There are also a lot of formulas that are not in the seven categories, but they are also useful, so they have been included as well.
The most important thing in this app is that it is user-friendly, so it is very easy to use, even for people who are not very familiar with mathematics. It is also very easy to add your own formulas and notes to the favorites section, so you can easily access them.
