# Ember vs REMI

The clearest difference is review sentiment: REMI at 76% against Ember's 18%. REMI also leads on update cadence (every 4 weeks vs every 2 months) and device support (3 vs 1). Ember's advantage is rating (3.3 vs 2.0) and in-app purchases (none vs 16). On price and ads there is nothing between them.

Both are free to download. REMI sells 16 one-off in-app purchases. Ember asks for nothing beyond the download.

Ember holds the better App Store score, 3.3 against 2.0. That said, the two scores are not equally well evidenced: Ember has 7.4K ratings behind it against 26, so its average is the more settled of the two. Written reviews complicate that: 18% of Ember's written reviews are positive against 76% of REMI'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, REMI every 4 weeks. The most recent releases landed on September 28, 2026 and September 29, 2026 respectively.
