Verdict
The clearest difference is in-app purchases: Epoch Core at none against Planet Gravity's 1. Epoch Core also leads on ads (none vs shown) and review sentiment (75% vs 44%). Planet Gravity's advantage is rating (4.2 vs 3.8) and update cadence (every 6 months vs every 18 months). On price and device support there is nothing between them.

Both are free to download. 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 6 months. The most recent releases landed on November 2, 2026 and November 3, 2026 respectively.
