# Cosmic vs EarthPi

The clearest difference is rating: Cosmic at 4.8 against EarthPi's 4.5. Cosmic also leads on review sentiment (87% vs 67%) and ratings volume (636 vs 16). EarthPi's advantage is update cadence (every 3 months vs every 6 months) and iOS requirement (12.0 vs 15.0). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Cosmic sells 6 in-app purchases, starting at $0.99 per month and EarthPi sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Cosmic holds the better App Store score, 4.8 against 4.5. That said, the two scores are not equally well evidenced: Cosmic has 636 ratings behind it against 16, so its average is the more settled of the two. Written reviews point the same way: 87% of Cosmic's written reviews are positive against 67% of EarthPi's.

Cosmic ships an update every 6 months, EarthPi every 3 months. The most recent releases landed on November 1, 2026 and October 30, 2026 respectively.
