Verdict
The clearest difference is review sentiment: Planetary Weather at 100% against GPT Solar System Explorer's 0%. Planetary Weather also leads on monetization model (free with in-app purchases vs subscription) and iOS requirement (6.0 vs 15.0). GPT Solar System Explorer's advantage is rating (4.7 vs 4.0) and update cadence (every 2 weeks vs every 7 months). On price, ads, in-app purchases and device support there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Planetary Weather 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 4.0. That said, the two scores are not equally well evidenced: GPT Solar System Explorer has 90 ratings behind it against 11, so its average is the more settled of the two. Written reviews complicate that: 100% of Planetary Weather'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.
Planetary Weather ships an update every 7 months, GPT Solar System Explorer every 2 weeks. The most recent releases landed on October 12, 2026 and October 8, 2026 respectively.
