Verdict
The clearest difference is monetization model: The Peptide App at free against PepStack Pro's freemium. The Peptide App also leads on ratings volume (86 vs 11). PepStack Pro's advantage is rating (5.0 vs 4.7) and device support (3 vs 1). On price, review sentiment, update cadence and ads there is nothing between them.

Both are free to download. The Peptide App sells 4 in-app purchases, starting at $4.99 per month and PepStack Pro sells 2 in-app purchases, starting at $8.99 per month. Whichever you choose, the download price is not the number that matters.
PepStack Pro holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: The Peptide App has 86 ratings behind it against 11, so its average is the more settled of the two. Written reviews split almost evenly too, at 100% and 100% positive.
