Verdict

The call

The clearest difference is update cadence: AX at every 2 months against Dual Smart EQ's every 11 months. AX also leads on rating (2.2 vs 2.0). Dual Smart EQ's advantage is ratings volume (21 vs 5) and iOS requirement (8.0 vs 12.1). On price, review sentiment, ads and in-app purchases there is nothing between them.
