I use it for navigation so I don't get lost. I can't say it's bad in that respect, but I can't say it's too good either, okay? (Mom sighs)

It works great in Uzbekistan and India. However, in Delhi, I sometimes had to change carriers manually.

Very useful for all seafarers. Didn't know the app for too long. Such a waste of $ for all those years using different apps for a fraction of gb/$ this app can offer.
