The app looks very stylish and easy to use, but I can't understand why does the American measurement system mps and yards cannot be changed to the European km/h and meters? These are the basics for European customers. Noone understands when the app shows 200 yards until the warning! OOONO - is this a bug or what? Please update.

Thank you for your feedback. The measurement system in the app follows your phone’s language and region settings. To switch between km and miles:
Open phone Settings
Scroll down; select System
Tap on Languages & Region.
Choose English, followed by a region that uses the metric system. If you choose English, the app will display miles instead of km.

I don't get the reviews here. It works fine. Yes, having kph would be nice but that doesn't warrant a one star rating. The battery usage is only high in first use, afterwards 1%\h. The device connects automatically when I enter the car and does NOT disconnect while driving. I would like to get the manual distance setting for warnings back as an option though. In general we need more options. Light and dark mode (preferably automatically depending on time of day and tunnels), customization, etc.

I just got this thing, downloaded the app and went for a short drive. After 5 minutes my phone was noticable warm inside my pocket. Is this app trying to farm crypto on my phone or what's going on? Also why can't I change to kmh? I thought this is like the marked leader of this kind of devices? This feels more like a cheap nock off..

Thank you for your feedback. Your phone getting warm isn’t how it should behave, so if it continues, please reach out to us at support@ooono.com.
The measurement system in the app follows your phone’s language and region settings. To switch between kilometres and miles, you’ll need to update these settings on your device.
