Verdict

The call

The clearest difference is price: Duolingo at Free against ASL Translator's $4.99. Duolingo also leads on rating (4.7 vs 4.1) and update cadence (weekly vs every 4 months). ASL Translator's advantage is in-app purchases (none vs 28) and ads (none vs shown). On review sentiment and device support there is nothing between them.

CostPrice · In-app purchases · Ads · Monetization

Duolingo is free to download; ASL Translator costs $4.99 up front. Duolingo sells 16 in-app purchases, starting at $9.99 per month. ASL Translator asks for nothing beyond the download.

ReceptionRating · Positive reviews · Number of ratings

Duolingo holds the better App Store score, 4.7 against 4.1. That said, the two scores are not equally well evidenced: Duolingo has 5.5M ratings behind it against 87, so its average is the more settled of the two. Written reviews complicate that: 69% of ASL Translator's written reviews are positive against 65% of Duolingo's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

ASL Translator ships an update every 4 months, Duolingo weekly. The most recent releases landed on September 22, 2026 and September 25, 2026 respectively.
