Verdict
The clearest difference is review sentiment: MobilEM at 45% against ACEP's 0%. MobilEM also leads on chart position (#48 vs unranked) and ratings volume (39 vs 8). ACEP's advantage is rating (4.3 vs 3.6) and in-app purchases (none vs 12). On price, update cadence, 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 12 in-app purchases, starting at $1.99 per year. ACEP asks for nothing beyond the download.
ACEP holds the better App Store score, 4.3 against 3.6. Both are backed by a comparable volume of ratings — 39 and 8 respectively. Written reviews complicate that: 45% of MobilEM's written reviews are positive against 0% of ACEP's, so the app with the better star average is not the one people write more warmly about.
MobilEM ships an update every 2 months, ACEP monthly. The most recent releases landed on September 20, 2026 and September 11, 2026 respectively.
