# Card.Note vs 研色

The clearest difference is price: Card.Note at Free against 研色's $1.99. Card.Note also leads on review sentiment (79% vs 38%) and ratings volume (81 vs 1). 研色's advantage is in-app purchases (none vs 2) and ads (none vs shown). On update cadence and device support there is nothing between them.

Card.Note is free to download; 研色 costs $1.99 up front. Card.Note sells 2 in-app purchases, starting at $0.99 per 7 days. 研色 asks for nothing beyond the download.

研色 holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: Card.Note has 81 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 79% of Card.Note's written reviews are positive against 38% of 研色's, so the app with the better star average is not the one people write more warmly about.

Card.Note ships an update every 2 weeks, 研色 fortnightly. The most recent releases landed on October 14, 2026 and October 6, 2026 respectively.
