Verdict
The clearest difference is in-app purchases: Sight Reading Factory at none against Notes Quiz (ノーツクイズ)'s 1. Sight Reading Factory also leads on ads (none vs shown) and rating (2.7 vs 2.3). Notes Quiz (ノーツクイズ)'s advantage is update cadence (every 2 weeks vs every 2 months) and review sentiment (43% vs 33%). On price 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. Notes Quiz (ノーツクイズ) sells 1 one-off in-app purchase. Sight Reading Factory asks for nothing beyond the download.
Sight Reading Factory holds the better App Store score, 2.7 against 2.3. That said, the two scores are not equally well evidenced: Sight Reading Factory has 391 ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 43% of Notes Quiz (ノーツクイズ)'s written reviews are positive against 33% of Sight Reading Factory's, so the app with the better star average is not the one people write more warmly about.
Notes Quiz (ノーツクイズ) ships an update every 2 weeks, Sight Reading Factory every 2 months. The most recent releases landed on October 24, 2026 and October 21, 2026 respectively.
