Verdict

The call

The clearest difference is price: Polyx 2D at Free against Einstein™ Brain Training's $2.99. Polyx 2D also leads on rating (5.0 vs 4.3) and update cadence (every 3 days vs every 2 months). Einstein™ Brain Training's advantage is ratings volume (26 vs 2) and chart position (#65 vs unranked). On ads, in-app purchases and device support there is nothing between them.
