# Fever Scout vs Thermometer

The clearest difference is rating: Thermometer at 4.6 against Fever Scout's 2.6. Thermometer also leads on update cadence (fortnightly vs every 2 months) and review sentiment (32% vs 17%). Fever Scout's advantage is in-app purchases (none vs 6) and iOS requirement (9.0 vs 15.0). On price, ads and device support there is nothing between them.

Both are free to download. Thermometer sells 6 in-app purchases, starting at $5.99 per 7 days. Fever Scout asks for nothing beyond the download.
