# Planets AR vs EarthPi

The clearest difference is rating: EarthPi at 4.5 against Planets AR's 3.7. EarthPi also leads on ads (none vs shown). Planets AR's advantage is review sentiment (100% vs 67%) and update cadence (daily vs every 3 months). On price, ratings volume, in-app purchases and monetization model there is nothing between them.

Both are free to download. Planets AR sells 2 one-off in-app purchases and EarthPi sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

EarthPi holds the better App Store score, 4.5 against 3.7. Both are backed by a comparable volume of ratings — 6 and 16 respectively. Written reviews complicate that: 100% of Planets AR's written reviews are positive against 67% of EarthPi's, so the app with the better star average is not the one people write more warmly about.

Planets AR ships an update daily, EarthPi every 3 months. Both last shipped on November 4, 2026.
