This is the app I've been waiting for, for a LONG time!
Equate Formula Solver is fully loaded with every mathematical, chemistry, geometrical, physics, you-name-it equation out there! They are easily found and accessed. The app displays the formula with empty boxes that are simply filled in and BAM! It calculates the right answer based on the information given.
The app also hosts videos that teach students why those formulas ARE the formulas for calculation, and how and when to use them. This is in addition to a LEARN IT! section that also further tutors on the use and specifics of each formula.
A perfect app that no student today should live without.
