# ASL Study vs TWA Dictionary

The clearest difference is rating: TWA Dictionary at 4.3 against ASL Study's 3.6. TWA Dictionary also leads on ads (none vs shown) and review sentiment (77% vs 43%). ASL Study's advantage is ratings volume (198 vs 31). On price, update cadence, in-app purchases and monetization model there is nothing between them.

Both are free to download. ASL Study sells 11 one-off in-app purchases and TWA Dictionary sells 5 in-app purchases, starting at $4.99 per month. Whichever you choose, the download price is not the number that matters.

TWA Dictionary holds the better App Store score, 4.3 against 3.6. That said, the two scores are not equally well evidenced: ASL Study has 198 ratings behind it against 31, so its average is the more settled of the two. Written reviews point the same way: 43% of ASL Study's written reviews are positive against 77% of TWA Dictionary's.

ASL Study ships an update fortnightly, TWA Dictionary every 3 weeks. The most recent releases landed on September 20, 2026 and September 21, 2026 respectively.
