Verdict

The call

The clearest difference is price: Peptide1 at Free against SkySafari's $6.99. Peptide1 also leads on in-app purchases (none vs 3) and update cadence (every 6 days vs monthly). SkySafari's advantage is ratings volume (18K vs 1) and chart position (#12 vs unranked). On ads, monetization model, device support and iOS requirement there is nothing between them.
