Peptide AI is a peptide tracker built for GLP-1s and broader peptide use. Track injections, doses, weight, side effects, notes, and progress in one place. Supports popular GLP-1 medications like Zepbound, Wegovy, Ozempic, and Mounjaro. A paid Peptide AI Pro subscription is required to access the app. Inside the app, members use the Home tab to log injections, nutrition, hydration, side effects, and daily notes; the Results tab to review weight and progress trends; and the Profile tab to manage reminders, Apple Health settings, and account preferences. Peptide AI can read Apple Health data such as weight, sleep, heart rate, steps, water, and nutrition, and can write manual weight entries and logged injections back to Apple Health when enabled. Peptide AI is an organizational and tracking tool, not medical advice.

Verdict
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.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
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.
