# Solar Lighting vs EarUnion

The clearest difference is review sentiment: EarUnion at 100% against Solar Lighting's 9%. EarUnion also leads on update cadence (every 5 weeks vs every 10 months). Solar Lighting's advantage is rating (2.4 vs 1.0) and ratings volume (14 vs 1). 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 Lighting holds the better App Store score, 2.4 against 1.0. That said, the two scores are not equally well evidenced: Solar Lighting has 14 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 9% of Solar Lighting's written reviews are positive against 100% of EarUnion's, so the app with the better star average is not the one people write more warmly about.

Solar Lighting ships an update every 10 months, EarUnion every 5 weeks. The most recent releases landed on September 9, 2026 and June 4, 2026 respectively.
