# Voice Dream vs Thorium

The clearest difference is in-app purchases: Thorium at none against Voice Dream's 10. Thorium also leads on ads (none vs shown) and review sentiment (67% vs 43%). Voice Dream's advantage is ratings volume (14K vs 2) and update cadence (every 3 weeks vs every 2 months). On price, rating and device support there is nothing between them.

Both are free to download. Voice Dream sells 10 in-app purchases, starting at $4.99 per month. Thorium asks for nothing beyond the download.
