Verdict

The call

The clearest difference is rating: EM at 4.8 against Pacemaker's 3.5. EM also leads on ratings volume (4.4K vs 62). Pacemaker's advantage is monetization model (free vs subscription) and update cadence (every 4 days vs every 6 weeks). On price, review sentiment, ads and in-app purchases there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

EM holds the better App Store score, 4.8 against 3.5. That said, the two scores are not equally well evidenced: EM has 4.4K ratings behind it against 62, so its average is the more settled of the two. Written reviews complicate that: 35% of EM's written reviews are positive against 38% of Pacemaker's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

EM ships an update every 6 weeks, Pacemaker every 4 days. The most recent releases landed on October 29, 2026 and October 30, 2026 respectively.
