# DuoCards vs SkillMirror AI

The clearest difference is ads: SkillMirror AI at none against DuoCards's shown. SkillMirror AI also leads on rating (5.0 vs 4.7). DuoCards's advantage is ratings volume (1.4K vs 1) and device support (3 vs 1). On price, update cadence, in-app purchases and monetization model there is nothing between them.

Both are free to download. DuoCards sells 10 in-app purchases, starting at $19.99 per month and SkillMirror AI sells 2 in-app purchases, starting at $9.99 per month. Whichever you choose, the download price is not the number that matters.

SkillMirror AI 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.

DuoCards ships an update monthly, SkillMirror AI every 3 weeks. The most recent releases landed on October 27, 2026 and October 6, 2026 respectively.
