The clearest difference is rating: Peptide Tracker at 4.8 against PepLog's 4.0. Peptide Tracker also leads on update cadence (weekly vs every 2 months) and ratings volume (102 vs 2). PepLog's advantage is ads (none vs shown) and monetization model (free vs free with in-app purchases). On price, review sentiment and in-app purchases there is nothing between them.

Both are free to download. PepLog sells 1 one-off in-app purchase and Peptide Tracker sells 12 in-app purchases, starting at $7.99 per 7 days. Whichever you choose, the download price is not the number that matters.

Peptide Tracker holds the better App Store score, 4.8 against 4.0. That said, the two scores are not equally well evidenced: Peptide Tracker has 102 ratings behind it against 2, so its average is the more settled of the two. Written reviews split almost evenly too, at 50% and 50% positive.
