Verdict
The clearest difference is review sentiment: Konvert at 79% against Sensors's 33%. Konvert also leads on rating (4.8 vs 2.0) and monetization model (free vs paid). Sensors's advantage is device support (3 vs 1) and iOS requirement (12.0 vs 26.0). On price, ads and in-app purchases there is nothing between them.
