# DOP 5 vs Orbit Slinger

The clearest difference is review sentiment: Orbit Slinger at 100% against DOP 5's 64%. Orbit Slinger also leads on ads (none vs shown) and monetization model (free vs free with in-app purchases). DOP 5's advantage is ratings volume (290K vs 8) and chart position (#145 vs unranked). On price, in-app purchases and device support there is nothing between them.
