# Intersign ASL vs Deduci

The clearest difference is update cadence: Deduci at every 3 days against Intersign ASL's monthly. Deduci also leads on rating (5.0 vs 4.7). Intersign ASL's advantage is ratings volume (4.8K vs 1) and iOS requirement (13.0 vs 17.0). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Intersign ASL sells 2 in-app purchases, starting at $6.99 per month and Deduci sells 1 in-app purchase, starting at $5.99 per month. Whichever you choose, the download price is not the number that matters.

Deduci holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: Intersign ASL has 4.8K ratings behind it against 1, so its average is the more settled of the two.

Intersign ASL ships an update monthly, Deduci every 3 days. The most recent releases landed on November 3, 2026 and October 31, 2026 respectively.
