# Peptide Tracker vs PeptideFox

The clearest difference is monetization model: PeptideFox at free against Peptide Tracker's subscription. PeptideFox also leads on rating (5.0 vs 4.7) and review sentiment (100% vs 77%). Peptide Tracker's advantage is ratings volume (305 vs 4). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Peptide Tracker sells 7 in-app purchases, starting at $3.99 per 7 days and PeptideFox sells 2 in-app purchases, starting at $2.99 per month. Whichever you choose, the download price is not the number that matters.

PeptideFox holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: Peptide Tracker has 305 ratings behind it against 4, so its average is the more settled of the two. Written reviews point the same way: 77% of Peptide Tracker's written reviews are positive against 100% of PeptideFox's.

Both ship on a similar rhythm, roughly weekly. Both last shipped on October 24, 2026.
