# Rock Pusher vs Harmonic Drive

The clearest difference is review sentiment: Harmonic Drive at 100% against Rock Pusher's 25%. Harmonic Drive also leads on rating (5.0 vs 4.5) and ads (none vs shown). Rock Pusher's advantage is ratings volume (10K vs 1) and iOS requirement (15.0 vs 18.6). On price, update cadence, in-app purchases and monetization model there is nothing between them.

Both are free to download. Rock Pusher sells 16 one-off in-app purchases and Harmonic Drive sells 10 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
