Units and language

Preferred units

Set each one to how you actually think:

• Air pressure — bar or psi.
• Distance — metres or feet.
• Temperature — °C or °F.
• Weight — kg or lb.

Display logs in preferred units converts dives that were logged in other units so your whole logbook reads the same way. Below that you choose the date format.

Language

Blue Trails is available in English, German, Spanish, French, Italian, Portuguese, Dutch, Chinese and Russian. Pick one and the app switches immediately.

The app follows your phone's language the first time you open it, so most people never need this screen — it's for when you'd rather use a different one.
