# Ultrahuman vs Sahha

The clearest difference is review sentiment: Sahha at 100% against Ultrahuman's 46%. Sahha also leads on in-app purchases (none vs 10) and ads (none vs shown). Ultrahuman's advantage is ratings volume (8K vs 1) and update cadence (every 3 days vs fortnightly). On price and iOS requirement there is nothing between them.

Both are free to download. Ultrahuman sells 10 in-app purchases, starting at $2.90 per month. Sahha asks for nothing beyond the download.

Sahha holds the better App Store score, 5.0 against 4.5.
