Verdict
The clearest difference is price: Sign ASL at Free against ASL Dictionary's $4.99. Sign ASL also leads on iOS requirement (13.0 vs 17.6). ASL Dictionary's advantage is rating (4.7 vs 4.1) and ads (none vs shown). On in-app purchases and device support there is nothing between them.

Sign ASL is free to download; ASL Dictionary costs $4.99 up front. Neither carries in-app purchases, so what you see is what you pay.
ASL Dictionary holds the better App Store score, 4.7 against 4.1. That said, the two scores are not equally well evidenced: ASL Dictionary has 1.3K ratings behind it against 90, so its average is the more settled of the two.

ASL Dictionary ships an update every 6 months, Sign ASL every 37 months. The most recent releases landed on October 27, 2026 and October 24, 2026 respectively.
