# Epoch Core vs Planet Gravity

The clearest difference is price: Epoch Core at Free against Planet Gravity's $11.00. Epoch Core also leads on in-app purchases (none vs 1) and ads (none vs shown). Planet Gravity's advantage is rating (4.2 vs 3.8) and update cadence (every 4 months vs every 18 months). On device support there is nothing between them.

Epoch Core is free to download; Planet Gravity costs $11.00 up front. Planet Gravity sells 1 one-off in-app purchase. Epoch Core asks for nothing beyond the download.

Planet Gravity holds the better App Store score, 4.2 against 3.8. That said, the two scores are not equally well evidenced: Planet Gravity has 54 ratings behind it against 5, so its average is the more settled of the two. Written reviews complicate that: 75% of Epoch Core's written reviews are positive against 44% of Planet Gravity's, so the app with the better star average is not the one people write more warmly about.

Epoch Core ships an update every 18 months, Planet Gravity every 4 months. The most recent releases landed on September 17, 2026 and October 15, 2026 respectively.
