Amovens is very similar to BlaBlaCar, a service that lets you carpool so you can travel more cheaply. The way it works is virtually identical to BlaBlaCar: you use the app to advertise any trips you're taking with the number of free seats in the car and the asking price for each. That way, if someone is interested in making the same trip, all they have to do is get in touch with you and pay through the app.
Amovens is a great application for traveling, making your trips much cheaper. Its only problem is that it's quite unstable and tends to have bugs. Its great advantage, however, is that it doesn't charge management fees.
