Verdict
The clearest difference is rating: 音圓N2 at 4.7 against IDExpert's 4.0. 音圓N2 also leads on ratings volume (84 vs 1). IDExpert's advantage is update cadence (every 5 weeks vs every 4 months) and review sentiment (11% vs 0%). On price, ads, in-app purchases and monetization model 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. Neither carries in-app purchases, so what you see is what you pay.
音圓N2 holds the better App Store score, 4.7 against 4.0. That said, the two scores are not equally well evidenced: 音圓N2 has 84 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 11% of IDExpert's written reviews are positive against 0% of 音圓N2's, so the app with the better star average is not the one people write more warmly about.
IDExpert ships an update every 5 weeks, 音圓N2 every 4 months. The most recent releases landed on September 29, 2026 and September 28, 2026 respectively.
