# Sign ASL vs Modal Math

The clearest difference is rating: Modal Math at 5.0 against Sign ASL's 4.1. Modal Math also leads on ads (none vs shown) and update cadence (every 5 weeks vs every 37 months). Sign ASL's advantage is in-app purchases (none vs 2) and ratings volume (90 vs 2). On price and device support there is nothing between them.

Both are free to download. Modal Math sells 2 in-app purchases, starting at $24.99 per month. Sign ASL asks for nothing beyond the download.

Modal Math holds the better App Store score, 5.0 against 4.1. That said, the two scores are not equally well evidenced: Sign ASL has 90 ratings behind it against 2, so its average is the more settled of the two.

Sign ASL ships an update every 37 months, Modal Math every 5 weeks. The most recent releases landed on November 2, 2026 and October 30, 2026 respectively.
