Verdict
The clearest difference is rating: Preface at 5.0 against MobilEM's 3.6. Preface also leads on in-app purchases (none vs 10) and update cadence (every 3 weeks vs every 2 months). MobilEM's advantage is ratings volume (39 vs 2) and chart position (#37 vs unranked). On price, ads and device support there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. MobilEM sells 10 in-app purchases, starting at $1.99 per year. Preface asks for nothing beyond the download.
Preface holds the better App Store score, 5.0 against 3.6. That said, the two scores are not equally well evidenced: MobilEM has 39 ratings behind it against 2, so its average is the more settled of the two.
MobilEM ships an update every 2 months, Preface every 3 weeks. The most recent releases landed on November 8, 2026 and October 30, 2026 respectively.
