PhotoMath is a camera application from the firm Microblink, with more than 100 million downloads and a 4.7 / 5 rating on Google Play, which solves mathematical problems of practically any type: the user takes a picture of the problem and the app returns the result in screen, immediately. Optionally you can review the steps that are followed to solve the problem. In some cases, various resolution methods (and even interactive graphics) are offered, the explanation of which is quite clear or understandable..
The app has evolved from just solving basic arithmetic problems like fractions, decimals, linear or first degree equations, functions like logarithms, etc. solve virtually any math problem, including algebra, trigonometry, calculus, and even statistics. Below you can see everything that the app is capable of solving simply by taking a picture of the problem.
Basic math / pre-algebra: arithmetic, whole numbers, fractions, decimal numbers, powers, roots, factors
Algebra: linear equations / inequalities, quadratic equations, systems of equations, logarithms, functions, matrices, graphs, polynomials
Trigonometry / pre-calculus: identities, sections conics, vectors, matrices, complex numbers, sequences and series, logarithmic functions
Calculus: limits, derivatives, integrals, drawing curves
Statistics: factorial combinations
In the beginning, the application could only read or scan textbook or print problems. Currently it also detects handwritten problems, although obviously the more illegible the letter, the more problems the app will have to understand.
Additionally, the application incorporates a scientific calculator, useful for working with equations..
Another cool thing about PhotoMath is that, according to its description on Google Play, it says that "its team of math experts work with teachers around the world to ensure that the most effective and contemporary teaching methodologies are used in our math engines."
Microblink, the company behind PhotoMath, is dedicated to developing mobile vision software, offering its technology to developers so they can integrate it into their own mobile applications. Development kits (SDKs) are available for your BlinkOCR (text scanning), BlinkBARCODE (barcode scanning), photoPAY (payment document scanning) and BlinkID (personal document scanning) technologies.
Alternatives
Although there are many applications on Google Play to solve math exercises with just your photo, such as MathWay , QANDA , « Camera Calculator «, each with millions of downloads as well and good average rating, unfortunately none has managed to surpass the prestige and number of users from PhotoMath, a pioneering app in this field, which was initially only available for iPhone, which is where it achieved fame. One of the reasons is that some of these apps are owned by independent developers, with fewer resources than companies like Microblink (probably some are even using the same SDK or technology from this company). That is the case with AutoMath , an application that came out shortly after PhotoMath, but is currently not being liked by users..
