# OpenEML vs OnePrime

The clearest difference is in-app purchases: OnePrime at none against OpenEML's 4. OnePrime also leads on rating (5.0 vs 4.8). OpenEML's advantage is ratings volume (32 vs 5). On price, review sentiment, update cadence and ads there is nothing between them.

Both are free to download. OpenEML sells 4 in-app purchases, starting at $1.99 per 7 days. OnePrime asks for nothing beyond the download.

OnePrime holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: OpenEML has 32 ratings behind it against 5, so its average is the more settled of the two. Written reviews split almost evenly too, at 100% and 100% positive.

OpenEML ships an update every 6 days, OnePrime weekly. Both last shipped on October 24, 2026.
