# Eternum Inc vs Supernova

The clearest difference is rating: Eternum Inc at 4.8 against Supernova's 4.5. Eternum Inc also leads on iOS requirement (13.0 vs 17.0). Supernova's advantage is review sentiment (78% vs 67%) and device support (5 vs 3). On price, ratings volume, update cadence and ads there is nothing between them.

Both are free to download. Eternum Inc sells 2 one-off in-app purchases and Supernova sells 10 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Eternum Inc holds the better App Store score, 4.8 against 4.5. Both are backed by a comparable volume of ratings — 190 and 75 respectively. Written reviews complicate that: 67% of Eternum Inc's written reviews are positive against 78% of Supernova's, so the app with the better star average is not the one people write more warmly about.

Both ship on a similar rhythm, roughly every 2 days. The most recent releases landed on October 28, 2026 and October 25, 2026 respectively.
