Verdict
The clearest difference is update cadence: Quantrack at every 2 days against Abacus Simulator's every 3 weeks. Quantrack also leads on rating (5.0 vs 4.7). Abacus Simulator's advantage is ratings volume (41 vs 1) and device support (3 vs 1). On price, ads, in-app purchases and monetization model there is nothing between them.
