Verdict
The clearest difference is rating: Ember at 3.3 against Kepwam's 2.6. Ember also leads on ratings volume (7.5K vs 8). Kepwam's advantage is update cadence (every 4 days vs every 2 months) and iOS requirement (12.0 vs 16.6). 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.
Ember holds the better App Store score, 3.3 against 2.6. That said, the two scores are not equally well evidenced: Ember has 7.5K ratings behind it against 8, so its average is the more settled of the two. Written reviews complicate that: 18% of Ember's written reviews are positive against 22% of Kepwam'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, Kepwam every 4 days. The most recent releases landed on October 18, 2026 and October 5, 2026 respectively.
