# PEPID® vs MobilEM

The clearest difference is rating: PEPID® at 4.7 against MobilEM's 3.6. PEPID® also leads on in-app purchases (none vs 12) and ratings volume (2.9K vs 39). MobilEM's advantage is chart position (#64 vs unranked). On price, review sentiment, update cadence and ads there is nothing between them.

Both are free to download. MobilEM sells 12 in-app purchases, starting at $1.99 per year. PEPID® asks for nothing beyond the download.

PEPID® holds the better App Store score, 4.7 against 3.6. That said, the two scores are not equally well evidenced: PEPID® has 2.9K ratings behind it against 39, so its average is the more settled of the two. Written reviews split almost evenly too, at 45% and 45% positive.

PEPID® ships an update every 5 weeks, MobilEM every 2 months. The most recent releases landed on October 10, 2026 and October 11, 2026 respectively.
