# Peptide AI vs ShotSync

The clearest difference is monetization model: ShotSync at freemium against Peptide AI's subscription. ShotSync also leads on rating (5.0 vs 4.8). Peptide AI's advantage is update cadence (weekly vs every 3 weeks) and ratings volume (26 vs 2). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Peptide AI sells 2 in-app purchases, starting at $14.99 per month and ShotSync sells 3 in-app purchases, starting at $7.99 per month. Whichever you choose, the download price is not the number that matters.

ShotSync holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: Peptide AI has 26 ratings behind it against 2, so its average is the more settled of the two.

Peptide AI ships an update weekly, ShotSync every 3 weeks. The most recent releases landed on October 6, 2026 and October 10, 2026 respectively.
