# SlimNation vs Sunnova

The clearest difference is rating: SlimNation at 5.0 against Sunnova's 3.9. Sunnova's advantage is update cadence (every 3 weeks vs every 4 months) and ratings volume (844 vs 1). On price, review sentiment, ads and in-app purchases there is nothing between them.

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

SlimNation holds the better App Store score, 5.0 against 3.9. That said, the two scores are not equally well evidenced: Sunnova has 844 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 0% of SlimNation's written reviews are positive against 6% of Sunnova's, so the app with the better star average is not the one people write more warmly about.

SlimNation ships an update every 4 months, Sunnova every 3 weeks. The most recent releases landed on June 1, 2026 and September 23, 2026 respectively.
