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 clearest difference is in-app purchases: Prime Checker at none against 瞬間素因数分解 Prime Factorization's 1. Prime Checker also leads on ads (none vs shown) and device support (4 vs 2). 瞬間素因数分解 Prime Factorization's advantage is update cadence (weekly vs every 17 months). On price there is nothing between them.
