# Solar Weather vs Solar Activity

The clearest difference is rating: Solar Weather at 3.4 against Solar Activity's 1.0. Solar Weather also leads on ads (none vs shown) and monetization model (free vs ad-supported). Solar Activity's advantage is review sentiment (25% vs 13%) and iOS requirement (15.0 vs 17.0). On price, in-app purchases and device support there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

Solar Weather holds the better App Store score, 3.4 against 1.0. That said, the two scores are not equally well evidenced: Solar Weather has 5 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 13% of Solar Weather's written reviews are positive against 25% of Solar Activity's, so the app with the better star average is not the one people write more warmly about.

Solar Weather ships an update every 6 weeks, Solar Activity every 3 months. The most recent releases landed on September 9, 2026 and September 10, 2026 respectively.
