# SController2.0 vs Solar Guardian

The clearest difference is review sentiment: SController2.0 at 100% against Solar Guardian's 17%. SController2.0 also leads on update cadence (daily vs every 2 months). Solar Guardian's advantage is rating (2.3 vs 2.0) and ratings volume (17 vs 3). On price, ads, in-app purchases and monetization model there is nothing between them.

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

Solar Guardian holds the better App Store score, 2.3 against 2.0. That said, the two scores are not equally well evidenced: Solar Guardian has 17 ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 100% of SController2.0's written reviews are positive against 17% of Solar Guardian's, so the app with the better star average is not the one people write more warmly about.

SController2.0 ships an update daily, Solar Guardian every 2 months. Both last shipped on October 24, 2026.
