# Mask App vs Ai Math

The clearest difference is in-app purchases: Ai Math at none against Mask App's 1. Ai Math also leads on update cadence (every 8 days vs every 2 months). Mask App's advantage is ads (none vs shown). On price, device support and iOS requirement there is nothing between them.

Both are free to download. Mask App sells 1 one-off in-app purchase. Ai Math asks for nothing beyond the download.

Mask App ships an update every 2 months, Ai Math every 8 days. The most recent releases landed on May 17, 2026 and June 10, 2026 respectively.
