# COSMOSIM vs Bluelly

The clearest difference is ads: Bluelly at none against COSMOSIM's shown. Bluelly also leads on monetization model (free vs free with in-app purchases) and update cadence (every 5 days vs fortnightly). COSMOSIM's advantage is ratings volume (28 vs 2) and iOS requirement (13.4 vs 15.1). 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 Bluelly. That said, the two scores are not equally well evidenced: COSMOSIM has 28 ratings behind it against 2, 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 fortnightly, Bluelly every 5 days. The most recent releases landed on September 15, 2026 and August 16, 2026 respectively.
