# Gun Clone vs Harmonic Drive

The clearest difference is review sentiment: Harmonic Drive at 100% against Gun Clone's 21%. Harmonic Drive also leads on ads (none vs shown) and rating (5.0 vs 4.7). Gun Clone's advantage is ratings volume (9.8K 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. Gun Clone sells 13 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.

Harmonic Drive holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: Gun Clone has 9.8K ratings behind it against 1, so its average is the more settled of the two. Written reviews point the same way: 21% of Gun Clone's written reviews are positive against 100% of Harmonic Drive's.

Both ship on a similar rhythm, roughly weekly. The most recent releases landed on September 29, 2026 and September 9, 2026 respectively.
