You can read a large list of physics formulae from this app.Also you can write your formula and save this into app.
By this way you can read it later.All kinds of symbol used in physics are given in list.
It has lots of useful features-

# Writing ability of user defined formula.
# Reading own created list later in real format.
# Almost all available cues are given.
# General,Greek,Unit Symbols are enlisted.
# Common used constants are listed with values.
# Very beautiful UI design.

Because the app has saving feature so it will be very useful for students.
You can delete saved things when needed.
I think you will be benefited if you use it.
Thank you.
