Verdict
The clearest difference is ads: Petrolin at none against COSMOSIM's shown. Petrolin also leads on monetization model (free vs free with in-app purchases) and update cadence (every 5 days vs every 2 weeks). COSMOSIM's advantage is ratings volume (35 vs 3). On price, rating, review sentiment and in-app purchases there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
On the App Store both sit at effectively the same score — 4.9 for COSMOSIM against 5.0 for Petrolin. That said, the two scores are not equally well evidenced: COSMOSIM has 35 ratings behind it against 3, so its average is the more settled of the two. Written reviews split almost evenly too, at 100% and 100% positive.
COSMOSIM ships an update every 2 weeks, Petrolin every 5 days. The most recent releases landed on October 27, 2026 and October 8, 2026 respectively.
