# Vivaldi vs Cognify

The clearest difference is in-app purchases: Vivaldi at none against Cognify's 3. Vivaldi also leads on device support (3 vs 1) and iOS requirement (12.1 vs 17.0). Cognify's advantage is update cadence (every 2 weeks vs every 4 months). On price and ads there is nothing between them.

Both are free to download. Cognify sells 3 in-app purchases, starting at $12.99 per month. Vivaldi asks for nothing beyond the download.

Vivaldi ships an update every 4 months, Cognify every 2 weeks. The most recent releases landed on October 5, 2026 and October 11, 2026 respectively.
