# Ember vs SlimNation

The clearest difference is rating: SlimNation at 5.0 against Ember's 3.3. Ember's advantage is ratings volume (7.4K vs 1) and review sentiment (18% vs 0%). 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.

SlimNation holds the better App Store score, 5.0 against 3.3. That said, the two scores are not equally well evidenced: Ember has 7.4K ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 18% of Ember's written reviews are positive against 0% of SlimNation's, so the app with the better star average is not the one people write more warmly about.

Ember ships an update every 2 months, SlimNation every 4 months. The most recent releases landed on September 25, 2026 and June 1, 2026 respectively.
