About this app

Formula Solver is a simple and easy-to-use application for physical and chemical calculations. It features 100+ of formulas in physics and chemistry, with images of the equations, descriptions of elements in the formulas and selector not only of base units for calculation but also the result unit. The formulas of physics are grouped into 12 categories, including electricity, magnetism, hydromechanics, mechanics, mechanics of vibration, mechanics of waves, mechanics of acoustics, molecular physics, thermodynamics, optics, quantum physics, and special theory of relativity. The application also features step-by-step instructions for some formulas. Whether you need help with solving equations in physics and chemistry, Formula Solver is an useful tool for any science enthusiast or student.

Ratings and reviews

Concept is good but it has a long way before it becomes usable. For instance, while calculating the height of a projectile, why am i expected to write the value of g. It could have filled in the defaults. Also why should i indicate what to find, can't you just find all the missing ones based on what has been filled? And then those nasty errors that keep popping up.

Please add a scientific keyboard with the app. The textboxes just open the default numpad, which is not sufficient. For instance charge of an electron cannot be typed with 19 zeros.

Poorly designed UI. Tested w/ mirror focal length, entered value for r, hit calculate & it said "Determine what you want to calculate" b/c entering a value doesn't auto-select the radio button. Selected the radio button next to radius (since that's the field I filled, & normally with radio buttons the one next to the field you fill is the one you select) & it said "Enter value of element: f." Had to select the radio button next to f to get it to work. Very unintuitive & cumbersome. +Other issues
