I recently updated River Level for iPhone to version 1.1. The main feature added to 1.1 is the ability to customise the units of measurement. Specifically:
- River depth: meters or feet;
- Water temperature: celsius or fahrenheit
Units of measurement can be customised by going to system Settings / River Level.
To make the user experience even smoother, the first river you add determines the default units of measurement. So if the first river you add is an American river, the units automatically default to feet/fahrenheit. This should remove the need for most users to access Settings.
River Level is free in the App Store.
