Features
Read full description

This application calculate values of given number which are described below: * Integer factorization * Euler's totient function * Primitive root (if exist) * x, y where x^2 + y^2 = p if p is 4n+1 * x, y where x^2 + 3y^2 = p if p is 3n+1 * x, y where x^2 + 2y^2 = p if p is 8n+1 or 8n+3 * x, y where x^2 - 2y^2 = p if p is 8n+1 or 8n+7 This application uses Fermat algorithm, Pollard's rho algorithm and Lenstra's ECM for factorization, Miller–Rabin algorithm for primality test

Verdict

The call

The clearest difference is ads: Prime Checker at none against Animal math training's shown. Prime Checker also leads on iOS requirement (12.4 vs 15.0). Animal math training's advantage is update cadence (fortnightly vs every 17 months). On price, in-app purchases and device support there is nothing between them.
