# 正字戰隊 vs EMM EDB

The clearest difference is review sentiment: 正字戰隊 at 100% against EMM EDB's 27%. 正字戰隊 also leads on update cadence (every 2 months vs every 5 months). EMM EDB's advantage is rating (5.0 vs 3.0) and in-app purchases (none vs 1). On price, ratings volume, ads and device support there is nothing between them.

Both are free to download. 正字戰隊 sells 1 one-off in-app purchase. EMM EDB asks for nothing beyond the download.

EMM EDB holds the better App Store score, 5.0 against 3.0. Both are backed by a comparable volume of ratings — 1 and 1 respectively. Written reviews complicate that: 100% of 正字戰隊's written reviews are positive against 27% of EMM EDB's, so the app with the better star average is not the one people write more warmly about.
