# DuoCards vs Watch Your Language

The clearest difference is ads: Watch Your Language at none against DuoCards's shown. Watch Your Language also leads on update cadence (every 4 days vs monthly) and rating (5.0 vs 4.7). DuoCards's advantage is ratings volume (1.5K vs 2) and iOS requirement (13.0 vs 18.0). On price, in-app purchases, monetization model 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 and Watch Your Language sells 7 in-app purchases, starting at $4.99 per month. Whichever you choose, the download price is not the number that matters.

Watch Your Language holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: DuoCards has 1.5K ratings behind it against 2, so its average is the more settled of the two.

DuoCards ships an update monthly, Watch Your Language every 4 days. The most recent releases landed on November 3, 2026 and October 31, 2026 respectively.
