# Inch Converter vs Hydrawise

The clearest difference is price: Hydrawise at Free against Inch Converter's $0.99. Hydrawise also leads on rating (4.7 vs 3.6) and update cadence (every 3 weeks vs every 6 months). Inch Converter's advantage is review sentiment (60% vs 39%). On ads, in-app purchases, device support and iOS requirement there is nothing between them.

Written reviews complicate that: 60% of Inch Converter's written reviews are positive against 39% of Hydrawise's, so the app with the better star average is not the one people write more warmly about.
