Verdict
The clearest difference is ratings volume: Peptide Tracker at 307 against SLAY STRONG's 3. Peptide Tracker also leads on update cadence (weekly vs monthly). SLAY STRONG's advantage is rating (5.0 vs 4.7) and iOS requirement (15.0 vs 18.6). On price, ads, in-app purchases and monetization model 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. SLAY STRONG sells 1 in-app purchase, starting at $399.99 per month and Peptide Tracker sells 7 in-app purchases, starting at $3.99 per 7 days. Whichever you choose, the download price is not the number that matters.
SLAY STRONG holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: Peptide Tracker has 307 ratings behind it against 3, so its average is the more settled of the two.
SLAY STRONG ships an update monthly, Peptide Tracker weekly. The most recent releases landed on October 21, 2026 and October 30, 2026 respectively.
