Verdict
The clearest difference is in-app purchases: Paul's Strength Book at none against Peptide Stack's 2. Paul's Strength Book also leads on ads (none vs shown) and iOS requirement (15.1 vs 18.0). Peptide Stack's advantage is update cadence (daily vs fortnightly). On price and device support there is nothing between them.
