# Planets AR vs GPT Solar System Explorer

The clearest difference is review sentiment: Planets AR at 100% against GPT Solar System Explorer's 0%. Planets AR also leads on monetization model (free with in-app purchases vs subscription) and update cadence (daily vs every 2 weeks). GPT Solar System Explorer's advantage is rating (4.7 vs 3.7) and ads (none vs shown). On price, in-app purchases and device support there is nothing between them.

Both are free to download. Planets AR sells 2 one-off in-app purchases and GPT Solar System Explorer sells 5 in-app purchases, starting at $5.99 per month. Whichever you choose, the download price is not the number that matters.

GPT Solar System Explorer holds the better App Store score, 4.7 against 3.7. That said, the two scores are not equally well evidenced: GPT Solar System Explorer has 96 ratings behind it against 6, so its average is the more settled of the two. Written reviews complicate that: 100% of Planets AR's written reviews are positive against 0% of GPT Solar System Explorer's, so the app with the better star average is not the one people write more warmly about.

Planets AR ships an update daily, GPT Solar System Explorer every 2 weeks. Both last shipped on November 4, 2026.
