# Thermometer vs Temperature Converter

The clearest difference is review sentiment: Temperature Converter at 91% against Thermometer's 30%. Temperature Converter also leads on ads (none vs shown) and rating (4.8 vs 4.4). Thermometer's advantage is update cadence (every 2 months vs every 6 months) and iOS requirement (13.0 vs 15.0).
