# Solar System Scope VR vs GPT Solar System Explorer

The clearest difference is monetization model: Solar System Scope VR at free with in-app purchases against GPT Solar System Explorer's subscription. Solar System Scope VR also leads on review sentiment (14% vs 0%) and iOS requirement (13.0 vs 15.0). GPT Solar System Explorer's advantage is update cadence (every 2 weeks vs every 39 months) and rating (4.7 vs 4.4). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Solar System Scope VR sells 1 one-off in-app purchase 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 4.4. Both are backed by a comparable volume of ratings — 28 and 90 respectively. Written reviews complicate that: 14% of Solar System Scope VR'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.

Solar System Scope VR ships an update every 39 months, GPT Solar System Explorer every 2 weeks. The most recent releases landed on September 30, 2026 and October 8, 2026 respectively.
