# DuoCards vs See.Guru

The clearest difference is review sentiment: DuoCards at 63% against See.Guru's 0%. DuoCards also leads on ratings volume (1.4K vs 1) and iOS requirement (13.0 vs 15.1). See.Guru's advantage is in-app purchases (none vs 11) and ads (none vs shown). On price and device support there is nothing between them.

Both are free to download. DuoCards sells 10 in-app purchases, starting at $19.99 per month. See.Guru asks for nothing beyond the download.

See.Guru holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: DuoCards has 1.4K ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 63% of DuoCards's written reviews are positive against 0% of See.Guru's, so the app with the better star average is not the one people write more warmly about.

DuoCards ships an update monthly, See.Guru weekly. The most recent releases landed on October 25, 2026 and October 20, 2026 respectively.
