# Soy vs Harmony

The clearest difference is in-app purchases: Soy at none against Harmony's 18. Soy also leads on ads (none vs shown). Harmony's advantage is update cadence (every 6 days vs fortnightly). On price, device support and iOS requirement there is nothing between them.

Both are free to download. Harmony sells 13 in-app purchases, starting at $4.99 per 7 days. Soy asks for nothing beyond the download.

Soy ships an update fortnightly, Harmony every 6 days. The most recent releases landed on October 30, 2026 and November 2, 2026 respectively.
